FINAL UPDATE FROM ANKER AFTER I RECORDED THIS 👇🏻 So after I recorded this video, I e-mailed Anker to ask for a refund. They sent me this back and I found the second paragraph very interesting... see underneath their response for my thoughts. "Dear Mark Wood, Thank you for your reply. Sorry to hear the issue persists. In this case, could you please provide the serial number printed on the USB-C charging cap (looks something like "SN: AC3ETM0826502043") so that we can double check if the one you got is our upgraded version? *Meanwhile, the issue should be improved a lot according to our full test and other customers' feedback, but the issue could not be solved completely due to the limitation of the current Qualcomm platform. We also have tried hard to balance the volume as well as the sound quality on this version.* If you're willing to return it for a refund instead, I will be happy to provide the return instructions after we verify the serial number. Looking forward to your reply." So if this isn't an acknowledgement that audio hiss exists in units still being sold and that Anker is fully aware of it, then I don't know what is. They highlight that the audio hiss should be 'improved' based on customer feedback in replacement units (notice improved, not fixed) and FINALLY, I get the confirmation that I've been waiting for: 'the issue could not be solved completely due to the limitation of the current Qualcomm platform'. So in a nut shell, Anker basically confirm that there is hiss, they tried to improve it, but could not solve it. So whilst I'm happy that Anker finally acknowledge that audio hiss is still a possibility if you buy the L2Ps - this still doesn't really explain why some people experience hiss and some people don't. So maybe we'll just have to let that one go. But at the very least, I hope I've helped to shed enough light on the audio hiss problem of the L2Ps so you can weigh it up in your purchase decision. Thanks for sticking with me on this one, I thought this would be a very simple review when I bought these. Apparently not! I will be continuing to pursue a return for my L2Ps and my regular L2s. PS: Can anyone confirm the 'due to the limitation of the current Qualcomm platform' part being a cause of audio hiss? Seems pretty vague to me.
So I've just received my l2p few days ago. After using it for that period of time I did not experience any audio hiss from my unit. Perhaps you might be sensitive to audio hiss? That might explain why some people experienced the hiss and some do not
I've got two replacements with not much difference. The hiss is muted during pause but it starts once again playback is resumed. Since the level of the hiss is constant and not volume controlled, you can hear it best when source volume is fully turned down during playback. And it is in the background all the time, when the music of a new track starts with low level its audible. One of the features I've bought them for is HearID. But even here the hiss makes it hard (almost impossible) to use this feature. The Liberty Air 2 are not much different in regard of this problem.
mrkwd - tech guy To whom it may concern: I have cut and pasted this anonymous amazon review that should help clarify the “white noise” (hiss) issue for prospective buyers: anonymous AMAZON REVIEW of Anker SOUNDCORE PRO’s : *ORIGINAL REVIEW* Just ordered these on January 4, 2020 and received iteration 1 of the product (knowing that iteration 2 currently ships to customers). Iteration 1 always has background white noise and hissing. If you advertise this product as high-end audiophile grade, expect your customers to know a thing or two about audio quality. Most customers will pick up on the white noise issue! It feels like Anker is trying to off-load their old iteration hardware, betting that a % of customers will tolerate the hissing and background noises that plague iteration 1 and that are supposedly fixed in iteration 2 (based on customer feedback). Anker should simply recall all the iteration 1 of this product and send exclusively iteration 2 hardware to their customers. Returning on the same day for a refund. Very disappointed. January 4, 2020 order = Iteration 1 *NEW REVIEW* Anker's customer service sent me a replacement pair of earbuds. They touched the hardware a bit and it helps. First off: the white noise is still here but toned down. They have admitted in details that due to the current Qualcomm platform, the white noise issue cannot be solved at the moment. Here is my updated review (going from a 1-star review to a 4-star review): the "electronic" noise is especially noticeable at the end of a song, when the song goes quiet. It is like I can hear the amplifier amplify nothing. And then if I stop playing music or hit the pause button, it feels like the buds go into sleep mode within a few seconds and the white noise stops completely. I haven't tried podcasts or spoken tracks (with no music) - I feel like this could bother me a lot more. When playing straight up music, all is good. The sound that comes out of the buds when music is playing is otherwise great. You cannot beat two drivers vs. 1 as seen on the Apple Airpods Pro or the WF-1000MX3. This is basic physics. There are no known true wireless buds that have dual drivers apart from the Liberty 2 Pro. 2 drivers mean that the 11mm driver can go all the way to 20hz, while the Knowles driver can go all the way up to 20khz, separately and concurrently. With only 1 driver like on the Airpods' or the Sony's, they have to compensate for the lack of reach in either end of the spectrum through the equalizer, but that comes with a loss in fidelity. So the sound when playing music on the Liberty 2 Pro's is better than many competitors, the hype is justified, and the product is well built. The battery life seems really good too. If these buds did not have that white noise issue and had active noise cancelling, Anker would own the market. Not 5-star because of the white noise issue. I would buy the buds again but when they are discounted.
Since the first moment I received the earbuds through Amazon, I realized that it was a faulty designed product, the hiss is a flaw that will always exist and persist, so i returned the product. IMO, the product should be definitively discontinued by Anker. We should be a very large 1% population unhappy with the product, they are cheating.
I appreciate you sharing your experience. I bought mine during the pre-order period and received them from the 1st public batch. I never experienced this problem with my set of L2P. This is why I don't talk about it in my review. However, I received a lot of comments and questions about this issue from my viewers and audience. I definitely agree there is a problem. Unfortunately I can't confirm it based on my own experience with this product. Kudos to you for staying honest and sharing your experience as it happened. I truly hope Anker can get this figured out and avoids this problem in the next version.
Thanks for sharing your experience with the L2Ps El Jefe - I'm a huge fan of your channel and you're actually a huge inspiration for my mine, so it means a lot that you watched my video. I still laugh when I remember how that brand sent you an offensive e-mail for putting out a less than positive review of their product 😂 It's frustrating that we're all having different experiences with the L2P. If I had a unit with zero hiss, they'd be one of the best budget earbuds I've ever tested. But all this 'hiss or no hiss' confusion makes it very hard for people to know where they stand. Keep doing what you're doing by the way sir.
Hey big jefe hope all is well with you. I have the liberty air 2 and I also have the hiss/soft white noise when music not playing, are you having any issues with the liberty air 2?? Much appreciated gracias..
Wish, I saw this review before I bought mine. Was so excited. There were sooo many good reviews. They hiss so bad. I even put my cheap earbuds in for comparison and those don't do it. Definitely returning these. I'm starting to think some people don't hear the hiss, because different individuals hear different frequencies. I'll definitely be looking through your reviews to find some new earbuds. So disappointed. 😩
Jim's Review Room mentioned the hiss too. There definitely is a slight hiss. I've sent mine back and the hiss is better but still there, but for me it's not a major issue because when I'm listening to music I really don't hear it. To me personally these are the best earbuds I've ever heard but I definitely want to check out the new 1more's.
I think you give an honest review and it’s nice that you did a follow up. I owned the Liberty 2 Pros for about a month before I saw your first video talking about the “hiss”. I realized that it was present the whole time but I only really noticed it prior to playing audio and after it stopped. Kind of like it’s activating and deactivating. During playback I didn’t notice a “hiss” and the sound, to me, was really nice and enjoyable. I’ve tried the Jabra 75t’s but was not impressed with the sound for the cost of those ear buds. Either way, I think you have a valid concern but for me it doesn’t affect my listening experience. Keep giving your honest opinions and doing what you do.
Anyone who has read reviews on Amazon knows that audio hiss is a major problem of the both the anker liberty pro 2 and anker liberty 2. Thank you for being an honest and thorough reviewer. Watching your review has saved me the hassle of purchasing these defective earbuds and subsequently deal with the returning process. Kinda makes you wonder why most other major review channels decided to completely ignore this problem . Subscribed.
I confirm - there was also a hiss in my Liberty 2 Pro (I sent it back). I compared these headphones with my friend's Edifier headphones - you can clearly see the problem after turning on the Prefect Piano application (Android) - the hissing in Souncors starts after starting the application (without touching the piano keys), while in Edifire there was absolute silence. Hissing is also heard at minimum volume. Sorry for the poor english.
My guess (and it's only a guess) is that the hiss is at a frequency some people can hear, and some people can't. That's what would make the most sense to me. If they had earbuds that didn't have the hiss, they would've sent those. So I'm guessing that all the earbuds have the hiss, but only some people can hear it.
Yeah, I have the hissing issue as well, which sucks because I really wanted these earbuds to be good (I mean they are, but this problem is really annoying), I did get a replacement supposedly improved, but I still had the same amount of annoying hiss. One thing's for sure, their customer service is amazing!
I bought the Anker soundcore life P2 and they have this exact problem! The left earbud has a prominent hiss, and when I remove the left earbud the right earbud has a lower hiss. The right earbud volume is also much lower than the left one. I know I have the life P2 and not the liberty 2 pro, but I thought I was going crazy until I found this video, now it makes sense! The left earbud is probably an older one that has the hiss and is louder, and the right one is probably a newer version that has an overall lower volume and therefore less hiss.
Well, perhaps they've been updated because I just purchased a pair of these and there is no hiss at all. They have the best audio quality I've heard yet in any earbud under $300...bar none.
Very glad that you pointed out this issue. Only you did! This is what I've been looking for before making the decision of purchasing. Thank you so much.
Great review man. Finally someone that thinks like I do. I don't accept the audio hiss and the bandaid fix that is trickery and not really fixing but only adding a new problem which is limiting volume. So many people that dont know any better get fooled. There are bluetooth /signal issues with most products I've tried and from many companies, not only Anker be it noise, compression or limited sound quality for whatever reason. This is why I have to stick with the Fiio BTR5 using LDAC wireless with my LG phone and just plug in the earphone or headphone I like. Using a high quality DAC, headphone amplifier and wireless connection is imperative to great audio. After that comes picking a headphone that suits your taste in sound signature. To try and get that all in one is nearly impossible for me. After my recent audio experiences with Anker I told them I'm not getting any more of their headphones until they reach minimum hifi levels. Recently and before I bought the BTR5 I tried the Soundcore Life Q10 which sounded like it was using a trickery processing type that reminded me of simulated surround sound. its got a wow factor when you put in on your head but quickly I notice songs I'm familiar with sound unnatural and simulated with surround type reverb! Its subtle but that's the trickery. I just cant believe people use these things daily and are listening to such weird manipulated audio without realizing. I could be wrong and maybe its something else with that audio chip their using that is causing the weird sound but its how it sounds to me,
Hi :-) I believe this is just electrical white noise, every amplifier that ever existed has it whether your ears can hear it or not. The balanced armature driver directed into your ear exaggerates that a little and that's what people hear as hiss. Some people are more sensitive to it I guess. Most ear buds have only a single driver unit that handle the full range frequencies so you would not notice it as much as the high frequencies are muffled a little but every BT earphone has this to some degree, I own dozens and can hear a little white noise in every set with the volume cranked. Most BT ear buds don't have dedicated balanced armature teeters for high frequencies like the Liberty Pros 2 do and that exaggerates the white noise a little. My opinion is that they are still the better sounding BT earbuds for listening to music and reproduce the full range and sound great I don't notice the issue at all and I have 0 issue with them. I love mine and purchased an extra set recently.
i have 2 bluetooth tws, one has hiss one does not which means its not a universal thing. the weird thing is, the one that hisses actually cost a bit more than the one that does not which is kind of weird. both cost around $30, much cheaper than anker one.
to get rid of this hiss . The whole patch have to be send back to factory ,to have a certain chip to be replaced . Anker is not the factory. So by doing so anker have to pay extra and recall all hissing product .but I think there is a deeper reason for this . There must be a deeper problem in the manufacturing proceed .So final story ... reduce volume .They win , some people don't mind .
I had the white ones for 2 weeks now. I did know about the issue and have tested them thoroughly. No hiss at all. Paired with Galaxy Note 10+. Sounds amazing.
I just bought these at a massive discount but honestly it's really nice to have someone being honest about it. You got a sub out of me. Although the first part of the video I was ready to click off, I'd suggest hitting with the harder facts first because I came from the other video and I don't think many people stuck around to see that you are genuine. Hopefully, the pair that I ordered doesn't have it but for 33 dollars it's my better bet for the time being because my dogs ate 2) 200 dollar pairs in the last month. Kind of over expensive earbuds for now at least until I can figure out how to train them to eat their dog treats and not my earbuds. Thanks for the honest review.
You are absolutely correct. I have the Soundcore Spirit X2 and experience the hiss you are talking about. The sound quality is very good, similar to the 1MORE true wireless but with a deeper lows. I don’t like the hiss but the sound is good. I take them off as soon as I stop listening to music because of the hiss, wish it was not present.
to clarify its only noticable when im on a tab that can play audio, or watching a movie, and i dont play any audio. So if i play them normally the hiss isnt loud enough to be a bother and I will probably learn to ignore it.
Great video. It is sad to hear that Anker did not fix the issue. I was planning to buy a pair of Liberty 2's but decided to not buy after your first video. Instead, I ordered 1 more stylish. I hope they will be good. Thanks for your honesty.
Yes, I'm disappointed as I had originally heard so many good things about the L2Ps and I really wanted to love them. The 1MORE's look sick, hoping to try them myself soon. Thanks for watching!
The figure of defective units is definitely much more higher than 1%. I, from VN, have returned my liberty air 2 to the maintenance store 2 times for battery and sound issues
Listening to this from Liberty air 2 with the same issue. :)))) 1% seems to be strong with these ones. I think I'll hope for a replacement and if it doesn't work I'll get 1more buds. Hopefully you've got a review of them too. Great vid!
Anker reached out to me explaining that their “updated” version had fixed the hiss and microphone issue. Was almost convinced until I saw your video. Thanks a lot for your review. You just saved me 130 bucks! 😊🇱🇰
No hiss on mine and the knew firmware update holy shit it blows away my $250 Powerbeats pro and my Sony and my bose .i sold all 3 and stayed with my liberty pro
Yep, mine hiss. It isn't massively heavy but it is there. I watched this review the day after I received my Nuraloop and I have also tested against my Sony WH-1000X M3, neither of these hiss. Silent until content begins and silent immediately after. The Soundcore Liberty 2 Pro have the hiss which seemingly coincides with the drivers kicking in and powering down pre and post playback.
Your not alone man. I bought the liberty 2 pros, they had hiss and the right earbud didn't work. Returned them and treated myself to the liberty 3 pros. They hissed as well.
Edit: L3P no longer hiss and are some of the best sounding earbuds I've ever had. ANC isn't amazing tho, on par with some 50$ earbuds with ANC. Not why I bought them though, just wanted the best sound out there.
hey i have just bought mine 3 days ago. can you try playing pure sinewave generated frequency at around 8khz. mine gets horrible at this range from 7khz to 9khz.
Anyone saying there is 0 hiss is either not hearing it, lying, or in denial. I'm 2 pairs in as well and both hiss. My second unit indeed had quieter hiss, but it's still very much there. That combined with the abysmal mic quality certainly damages the overall experience. They are still good headphones. But combining that with the fact that they WILL NOT replace a single defective part, I wouldn't purchase again. You loose or break the case or one earbud, you have to buy a new pair. That's a serious problem.
I got an updated pair and I think I'll keep this one. The background white noise/hiss has been reduced to a level that I can live with. It's there if I listen for it, but it's nowhere near the loudness of the first pair I got. As for whether there's a volume reduction in my new pair, I think there is, but it's only slightly.
I Believe you bro!!! You are right!!! cause I've seen other reviews and comments about this same hissing problem!!!! SHAME ON SOUND CORE ANKER!!!!! Thank you for Your Honesty!!!! Frank Coleman 😊
I only hear it when I get a notification but never during music, calls or nothing playing at all. It's maybe a second if that. Not w big deal or something that makes me want to return them
If u dont hear it doesn't mean it isn't there and color the og sound , maybe people that doesn't have high end headphones cannot perceive the difference
Okay so found something really interesting, if you try listening to your music with "Hear ID" on you will not experience the "Hiss" sound. As soon as I switch to different audio profiles I can hear the hissing sound. Do let me know if you experience the same. Btw thanks for the FINAL UPDATE FROM ANKER AFTER after this video.
I am releasing my review of these tomorrow and hadn't noticed a hiss. Now that you've mentioned it I'm testing them again, and if we're talking about the same thing then I wouldn't describe it as hiss, and I certainly wouldn't describe it as "hissing like an anaconda". Hiss is far too strong a word, and I imagine that's why other people are struggling to agree with you. It's more like a very quiet analogue tape sound, and it's a sound that I think is audible in most earbuds, I can hear the same sound in my Google Pixel buds for example, but only a split second before the music kicks in, which makes me wonder if the sound is actually present in ALL earbuds, just that others are better at muting it until sound is playing. I'm not saying there's no noise, but either you're exaggerating when you say "hissing like an anaconda", or we're hearing two different things.
Hey Paul, you're correct - it's 100% over-exaggerating for effect when I say 'hissing like an anaconda' because of course, they are not literally hissing like snake 🐍! But I simply use that tongue-in-cheek phrase to highlight that the L2Ps are one of the worst hissing/audio static true wireless earbuds I've ever heard. For example, if I had to rate all the buds I've tested out on a scale from 0-10 (or silence to anaconda-level, if you will) in severity of hiss, the L2Ps would be a 10. Hiss is not a word I decided upon myself, if you Google 'Liberty 2 Pro audio hiss', that's what people initially referred to it as, so I continued to refer to it as that. Even analogue tape sound is referred to as tape hiss! That exact sound you're referring to is all I meant - some people prefer to call it audio static, but it's all the same thing. Yes, there are buds out there with hiss, but there are also tons of buds with zero hiss. Even in buds which are much cheaper - hence why I personally feel that any level of hiss, especially during playback, isn't something consumers necessarily need to tolerate. You have to bear in mind that in the original units of the L2Ps (I pre-ordered mine and got them on day 1), the audio hiss was noticeably worse than those released recently (the overall volume reduction reduced the hiss). So my original opinion may seem over-exaggerated if you're listening to a pair of L2Ps purchased recently. Either way, thanks for coming over to ask me! Look forward to watching your review - I just subbed as your channel looks awesome 🔥
@@mrkwd Thanks dude, and I fully appreciate exaggerating for effect. I am about as over the top as it gets 😂 I guess I can't think of a better word for it either, it's just that "hiss" is a cold word, whereas I think this is a warm sound and actually quite pleasant, it might sound odd, but I kind of like it! I didn't notice it at all until you mentioned it, but I wonder if subconsciously it was one of the reasons I really like their overall sound. Many engineers mix a little analogue tape sound into their music intentionally to give it warmth, there are plugins devoted to recreating this sound for digital recordings, because without it a digital recording sounds soul-less and flat. I've personally used a plugin called J37 Tape Saturation by Waves on my bands recordings as without it the record just sounded sharp and ugly, I kept finding myself increasing the bass, and dropping the treble, and adding de-essers to instruments, but nothing I did sounded right until I just added a VERY subtle amount of tape saturation to the master channel. Another odd effect that distortion has is that instead of hiding sound, it can actually improve clarity, it makes me wonder if the noise we're hearing is a byproduct of something they're doing, or if it's an intentional effect. The other thought I had, was that the internal components of these buds are lined up very differently from other buds, the daft name they've given it is Astria Coaxial Acoustic audio, but what they're actually saying is they've made the sound clearer by having the tweeter and the woofer both pointing straight at your ear, I wonder if the noise is always there in bluetooth earbuds, but is more evident because of the way they've lined up the little speakers. Each to their own either way. I love these earbuds, but everyone is different. Your channel also looks awesome, I admire your honesty and I'm amazed at how well you've handled the criticism in your comments section. I have a sock puppet specifically for calling those people names 🤣
I had the hisssssssss. Drove me nuts I had to return them. I even wrote a review on amazon.ca because of it. It's too bad because they did sound good but without the hiss would have sounded amazing! I also didn't find them the most comfortable.
I've got the liberty 2 non pro's and there is a slight hiss as mentioned but only when there's nothing playing. When listening to music or podcasts I don't hear it at all, even at low volume. I could care less if there's a little hiss when there's nothing playing. Different story if the hiss was audible during playback. That said, want to sell the original pair? I'll buy them from you, lol. I wanted the pros, but I couldn't find them anywhere and impulse bought the regular ones.
I will subscribe based on this single video itself. Got mine liberty air 2 last week and notice the hissing sound the first time I used it. Send it back right away and this is their responds: "According to our testing, there was no hissing sound heard by the technician. We suspect that the hissing sound can only be heard by the young generation like you where people with some ages like our technician didn't suffer from such issues. As such, replacing a brand new earbud for you won't solve the problem. You can either choose to refund or get back the original buds you sent us. " REFUNDED
Just received a second liberty pro 2 it sounded amazing, no white noise hissing when it comes to pausing the audio with no volume, calling didn't have that issue. When I reused it, the issue came back.. this time instead of the white noise on my 1st liberty pro 2 was 2 seconds. My replacement is now 4 seconds which added 2 second and I am annoyed that I thought I did not get a defect but within a few hours now it does not work well. I thought these 2nd pair would be the improved 2 iteration of the Soundcore liberty pro 2. I have bought Anker products like the usb type c, power banks and now the earbuds. Its very discouraging getting a 2nd product that i thought was not a defect without any hissing for a couple of hours when i first received it. This is my second pair and i went on the sound core forum on liberty pro 2 and many consumers who bought your product has white hissing noise. I do enjoy this, but if i return this. There is still a chance that i will get the white hiss unit. I don't really want to waste more time and have hope that i will get a good liberty pro 2
Man, i have 2 pairs of the liberty 2 pro's (black) and neither one of them have even a slight hiss....NOTHING. I did hear about the hiss tho from other reviewers. I DID however have problems updating firmware on my first pair i bought that i sent back for a replacement. Then the replacements updated to the 1.22 firmware like the first pair should've . Is your firmware updated? I wonder if the voice assistant feature is part of the reason for the hiss because the way I have both of mine set up is that the double press on either side moves tracks forward and back and then the long press for one or two seconds is volume up and down. I have no button control for voice assistant because I'm not going to ever use it. Maybe that voice assistant feature is messing with the hiss? I don't know.
I think thats actually a good theory! Would totally make sense to me as voice assistant has already messed with some of my former haedphones.. I've ordered them a few days ago, they should arrive today. I'm gonna test that and wirte another reply then :D
I know this is an old video but found if you set the buttons on the buds to long press works the volume, if you then lower the volume it reduces the hiss, and I'm not taking the piss lol. It reduces the volume of the buds themselves independent of phone volume you can then increase the phone volume. Hiss is still there but a little lower. I'm in the process of returning mine. So just a tip for anyone else.
Thank you so much for the honest and informative review and for being unwavering by commenters' and Anker's responses. Your review is excellent and very helpful in my decision about Anker Liberty 2 Pro. Keep up the great work!👍
Well done, there's a design flaw with these guys and Anker are giving us the runaround, complete time wasters, I'm sending mine back. Here's the worrying part, what do the 10 "top producers" sponsoring the L2P think...assuming they've even bothered giving them a listen !
Three units later for me and all of them had this hiss. I think I'm done with Anker altogether, maybe if they release a Liberty 3 that doesn't have this issue I'll give them another go.
You are definitely on to something as many "real" reviewers have reported hissing and sound issues with this these earbuds, and so many "other" (i'm polite here) reviewers have been saying they are the best under $200 are dishonest as we know now from inside sources , soundcore themselves, that they offer $8,000 per 200 units sold through affiliate links to reviewers, that is is $40 per unit , considering that some real audiophile reviewers have said that these earbuds sound completely off , says a lot about why soundcore is so shifty about it . good on you fella 👍
Mine have had hiss since I got them. I mainly use them for RUclips videos, so it's never bothered me too much until today when I compared them back and forth to my new Galaxy Buds Pros and it's all I can hear now. I'm gonna contact Anker to see if they can replace them.
Got mine today and didn‘t have audio hissing or white noise. I heard and read a lot of reviews on youtube and amazon and was really hesitating to buy them. After I was still disapointed from the airpods and earpods pro, I decided to give it a try. I‘m glad that I didn‘t have the problem in the situation you described. So far I don‘t have much experience with the earbuds but I really like that they stay in position and have a solid and controlled bass which I really missed withe my airpods pro
I watched your review a while ago. I also contemplated buying these for a long time. I ended up buying them. I hear the audio hiss before, during, and after playback. I listen to a few different genres and some songs drown out the hiss.
I believed you! I had the same issue with the hiss! Anker was nice enough to send me a new pair..the new pair still had a hiss but it wasn't half as loud.
Kudos to a very honest review. It shows you know what you are talking about and are confident enough to stand your ground even while facing such a huge amount of flak in the comments. Personally I am still very interested in these headphones due to the separate drivers covering the full audio spectrum. Its like having 2 way speakers instead of a full range. We know that there is hardly any comparison even with quality full-range drivers. I have experienced this type of hiss you describe quite often and I have a feeling it also has something to do with the audio codecs as much as the hardware itself. Even original music is sometimes recorded at source with hiss. I personally listen to such earphones at high volume during a workout so the hiss becomes a non issue. There is a way Anker could reduce it by rolling off the high end of the spectrum at the amplifier output, but that would mean that you would not be hearing the full music spectrum. If I had a choice between suppressing the highs or enduring a little hiss, then I would go for the hiss every time. However I'm posting this comment only based on my audio experience in general and without having heard these headphones. So I will update this post right after I order my headphones and having run them in a bit. Thanks again for your refreshingly honest reviews. I am now a subscriber. :)
Download the app and set the sound to your own ears, your review has not touched the surface of what these buds are capable off, They are absolutely awesome.
I got mine yesterday I noticed a very very slight hiss which is not noticeble but when I hear the same song on Amazon prime music I hear no hiss but I hear them on Spotify don't know it it's related to codec but I can definitely say one thing that it's sound quality is some next level because I own a wide range of headphones like beats solo wireless 3, liberty 2 pro is like much better than everything and also if you set up hear id you could hear very less hiss But I am very great full for your honest review really honesty is very rare among RUclipsrs now a days so keep up the good work brother 😍
I believe in you, because I had same issue on my b&w px headphone. Such a well known brand but unfortunately I received the defective set. When asked for exchanges, they rejected me because they thought I was being fussy. It was so frustrated, and helpless because no one willing to believe me. Until today, I have never worn it again.
I believe you and I'm also disappointed with some of the other reviewers that ignored the problem. Although Flossy Carter did mention this issue but he's the only one who did. Thank you for your reviews I'm going to avoid these earbuds.👍
Some people's ears may not be able to hear the hiss. I know that from years of shooting, I cannot hear certain frequencies at all. Could be one theory as to why some reviewers are not hearing the hiss and some are? I have old Anker Liberty Zolo wireless earbuds and still love them to this day after owning them for over a year. I only paid $50 USD for them. Good review, I never had a doubt in your honesty. 👍
Just got mine today and ran them through all the test with music on low and high volume. Changed stations and no hiss sound at all. So far so good. Out of this world. Great sound and bass. Mine came from Amazon.
Fishing with Gabriel no, I did not get the white ones. Had to return them because phone to phone communication was really bad on both ends. A lot of cutting in and out.
Now when you say it i can notice that hiss 1 second before and one second after I press play and I can hear it slightly when the music is playing unless I have full volume
It's the qualcomm cvc noise cancellation issue. I bought a jbl tune120tws and my friend bought a soundcore liberty air 2 a few days ago during online discount sales. The soundcore feature list made me regret buying the jbl. But then, I played a few songs on both back to back connected to same device, tested on 2 devices. The JBL sound quality is just way better, no hiss, clear crisp sound, better bass response. My regrets are gone. Don't mind missing a few features in exchange for sound quality.
It's March 2022 I just bought a pair and they do have a hiss right when I press play it's a very audible hiss but it stops after a few seconds and then starts again when I pause the video I can't hear it during playback no matter how low or loud volume is
My pair also hisses, but I didn't notice it until I watched your videos today. :P On my pair it's so quiet that it hasn't bothered me at all up to this point.
I wonder if this hiss issue discrepancy between listeners is due to some folks having tinnitus. Sound engineers and musicians have spent their lives around music (some/most of it loud) and suffer from varying degrees of hearing loss. I'm curious, if mrkwd has unadulterated ears (no basement punk shows) and can pick up the 'background noise' better.. I wonder what the frequency is. If it is quite high, chances are folks with any hearing loss whatsoever may not pick it up.
I have a set of the liberty air 2 and I'm having the same issue...its white/pink noise in 5he backroom before music starts then it's not super noticeable but when music stops then the white.noise is there again...I'm getting ready to contact soundcore myself..I own a pair of 20 dollars TWS Enacfire g20 and I have no white noise what so ever..
I got mine for my Birthday yesterday, on the barcode it titled "refurbished" and the Hissing/White Noise is very noticable as explained of many Users at the Beginning of a Song or Video, and when paused it stops after like 3-4 seconds because the Earbuds go in Stand-by-Mode. Pretty sad...😅 My Brothers owns a Pair of Liberty 2 (not Pro) that don't hiss at all. Gonna return them and see what i get in return
I'm glad i didn't get unlucky like you i hear no hiss what so ever and love my pair still at the same time I respect your opinion and honesty with your personal experience
I have had mine now for about a month. NO HISS.... I've tried connecting to various sources (phones, TV's) ... still No Hiss... and just in case I am personally deaf to the hiss frequency, I had both of my sons try them and they didn't hear any hiss either. As a result I am happy to say the sound is fantastic. I decided to roll the dice and buy these a month ago as they were on sale for only $149 CDN, and if they had hiss, back they would go... seems I may have gotten lucky.
I have purchased a unit of the anker soundcore life dot 2 and for a couple of days I tought I was developing tinittus. The "hiss" is horrible and lasts for up to two days from a short session.
I watched many earbud review videos and had just ordered the Anker Pro 2s for $129 Amazon. But as RUclips knew I was watching Anker videos so right after my order I see your video. I wanted a trouble free quality sound and my main source Flossy glowed about them. Bottom line your thoroughness moved me to cancel and change my order to the Jabra 75ts. I have more earbuds and headphones than any one person needs but my last purchase was Soundpeats dual driver which I kind of liked for the $. I hardly use them as I use my Bose headphones on lockdown. But I tried them a few days ago and 1 driver is shot. Bought them direct from China so I’m screwed. Thanks for your persistence. I would have bought the Sony’s but their size concerned me for the price. Many reviewers like the Jabras, hope I like. Sound quality first for me. I like Anker’s products overall, hope next time their great!
I wasn't playing and I just got the Sennheiser Momentum True wireless. Good God . I love them .. I get and understand budget but hands down they're the best . Excellent review .. keep em coming . May be looking for a backup for work
@James Torres, Those sound pretty great and fit my ears absolutely perfect too, but I don’t know what “hands down” means. Some others sound as good, including these Lbrty2Pro if you get the personalized hearing right and avoid the so called “hiss”.(I have yet to notice that) But the problem with Momentum is that the charge case drains constantly and doesn’t last long enough to serve it’s purpose effectively. At first, it doesn’t seem to matter much. They do sound so good and have that great ambient mode that you’re not worried about the battery. Later on though, it gets annoying when you realize how often you have no battery and need to recharge the whole thing. Jussayin... That’s my experience anyway.
I'm sure I'll encounter this problem .. I follow what you're saying and for me the sound is the payoff. Thank you and I appreciate your input .. outstanding reviews
I really liked your honset review + the update video. I bought these yesterday on sale on Ali express for about 100$ after watching a lot of reviews praising them and one even saying they are on par with the Sony's wf-1000xm3 and the Sennheiser's Momentum TWS 2 audio wise. I did watched a video by Jim's Review Room on these and he did mentioned a slight hiss but only low volume levels.
That sucks you had that issue mine fortunately work great and I absolutely love them, great sound and the app provides some good features. Keep up the awesome work
Ughh I really was hoping it was an isolated incident. Unfortunately, mine do have a noticeable hiss as well. When I emailed to try a second pair, they replied that mine are actually the newer version and basically the experience I have is what it is. So it's not going to get any better until they put a new one out. Sending it in for a refund. Recommendations for something in this price range? I enjoyed my Sabbat E12 Ultras, but was hoping for something a bit less muddy but still good bass this time around.
i got my l2p just 3 days ago. my issue is that when low freq music is played it covers the hiss. now when i play something like 8khz pure sinwave generated frequency i feel that the hiss gets louder and i cant hear the note purely. can someone confirm that this issue is that same everyone is facing or if its something thats the fault of my specific product? the issue lies from about 7khz to 10khz.
Thanks for the honest review, I bought the Pxc 550 II from Sennheiser but they have an audio hiss. Returned and bought the Sony xm3 and going to buy m50xbt
I read somewhere it could be iPhone problem, can you discount this has i have Android and if true want these buds, they seem to have everything but are ruined by this ????
Wow, I wish I would have seen this before buying these. They absolutely hiss, and quite loudly. If you’re listening to music it isn’t a big deal but I listen to audio books with these and it sounds like a garden hose is spraying in the back ground. It’s incredibly distracting, these will be returned.
FINAL UPDATE FROM ANKER AFTER I RECORDED THIS 👇🏻
So after I recorded this video, I e-mailed Anker to ask for a refund. They sent me this back and I found the second paragraph very interesting... see underneath their response for my thoughts.
"Dear Mark Wood,
Thank you for your reply.
Sorry to hear the issue persists. In this case, could you please provide the serial number printed on the USB-C charging cap (looks something like "SN: AC3ETM0826502043") so that we can double check if the one you got is our upgraded version?
*Meanwhile, the issue should be improved a lot according to our full test and other customers' feedback, but the issue could not be solved completely due to the limitation of the current Qualcomm platform. We also have tried hard to balance the volume as well as the sound quality on this version.*
If you're willing to return it for a refund instead, I will be happy to provide the return instructions after we verify the serial number.
Looking forward to your reply."
So if this isn't an acknowledgement that audio hiss exists in units still being sold and that Anker is fully aware of it, then I don't know what is. They highlight that the audio hiss should be 'improved' based on customer feedback in replacement units (notice improved, not fixed) and FINALLY, I get the confirmation that I've been waiting for: 'the issue could not be solved completely due to the limitation of the current Qualcomm platform'.
So in a nut shell, Anker basically confirm that there is hiss, they tried to improve it, but could not solve it. So whilst I'm happy that Anker finally acknowledge that audio hiss is still a possibility if you buy the L2Ps - this still doesn't really explain why some people experience hiss and some people don't. So maybe we'll just have to let that one go.
But at the very least, I hope I've helped to shed enough light on the audio hiss problem of the L2Ps so you can weigh it up in your purchase decision. Thanks for sticking with me on this one, I thought this would be a very simple review when I bought these. Apparently not! I will be continuing to pursue a return for my L2Ps and my regular L2s.
PS: Can anyone confirm the 'due to the limitation of the current Qualcomm platform' part being a cause of audio hiss? Seems pretty vague to me.
So I've just received my l2p few days ago. After using it for that period of time I did not experience any audio hiss from my unit. Perhaps you might be sensitive to audio hiss? That might explain why some people experienced the hiss and some do not
I've got two replacements with not much difference. The hiss is muted during pause but it starts once again playback is resumed. Since the level of the hiss is constant and not volume controlled, you can hear it best when source volume is fully turned down during playback. And it is in the background all the time, when the music of a new track starts with low level its audible. One of the features I've bought them for is HearID. But even here the hiss makes it hard (almost impossible) to use this feature. The Liberty Air 2 are not much different in regard of this problem.
mrkwd - tech guy
To whom it may concern:
I have cut and pasted this anonymous amazon review that should help clarify the “white noise” (hiss) issue for prospective buyers:
anonymous AMAZON REVIEW of Anker SOUNDCORE PRO’s :
*ORIGINAL REVIEW*
Just ordered these on January 4, 2020 and received iteration 1 of the product (knowing that iteration 2 currently ships to customers). Iteration 1 always has background white noise and hissing. If you advertise this product as high-end audiophile grade, expect your customers to know a thing or two about audio quality. Most customers will pick up on the white noise issue!
It feels like Anker is trying to off-load their old iteration hardware, betting that a % of customers will tolerate the hissing and background noises that plague iteration 1 and that are supposedly fixed in iteration 2 (based on customer feedback).
Anker should simply recall all the iteration 1 of this product and send exclusively iteration 2 hardware to their customers. Returning on the same day for a refund. Very disappointed.
January 4, 2020 order = Iteration 1
*NEW REVIEW*
Anker's customer service sent me a replacement pair of earbuds. They touched the hardware a bit and it helps. First off: the white noise is still here but toned down. They have admitted in details that due to the current Qualcomm platform, the white noise issue cannot be solved at the moment.
Here is my updated review (going from a 1-star review to a 4-star review): the "electronic" noise is especially noticeable at the end of a song, when the song goes quiet. It is like I can hear the amplifier amplify nothing. And then if I stop playing music or hit the pause button, it feels like the buds go into sleep mode within a few seconds and the white noise stops completely. I haven't tried podcasts or spoken tracks (with no music) - I feel like this could bother me a lot more. When playing straight up music, all is good.
The sound that comes out of the buds when music is playing is otherwise great. You cannot beat two drivers vs. 1 as seen on the Apple Airpods Pro or the WF-1000MX3. This is basic physics. There are no known true wireless buds that have dual drivers apart from the Liberty 2 Pro. 2 drivers mean that the 11mm driver can go all the way to 20hz, while the Knowles driver can go all the way up to 20khz, separately and concurrently. With only 1 driver like on the Airpods' or the Sony's, they have to compensate for the lack of reach in either end of the spectrum through the equalizer, but that comes with a loss in fidelity.
So the sound when playing music on the Liberty 2 Pro's is better than many competitors, the hype is justified, and the product is well built. The battery life seems really good too.
If these buds did not have that white noise issue and had active noise cancelling, Anker would own the market.
Not 5-star because of the white noise issue. I would buy the buds again but when they are discounted.
Since the first moment I received the earbuds through Amazon, I realized that it was a faulty designed product, the hiss is a flaw that will always exist and persist, so i returned the product. IMO, the product should be definitively discontinued by Anker. We should be a very large 1% population unhappy with the product, they are cheating.
Did you send them your first earbuds or u have 2 now?
I appreciate you sharing your experience. I bought mine during the pre-order period and received them from the 1st public batch. I never experienced this problem with my set of L2P. This is why I don't talk about it in my review. However, I received a lot of comments and questions about this issue from my viewers and audience. I definitely agree there is a problem. Unfortunately I can't confirm it based on my own experience with this product.
Kudos to you for staying honest and sharing your experience as it happened. I truly hope Anker can get this figured out and avoids this problem in the next version.
Thanks for sharing your experience with the L2Ps El Jefe - I'm a huge fan of your channel and you're actually a huge inspiration for my mine, so it means a lot that you watched my video. I still laugh when I remember how that brand sent you an offensive e-mail for putting out a less than positive review of their product 😂
It's frustrating that we're all having different experiences with the L2P. If I had a unit with zero hiss, they'd be one of the best budget earbuds I've ever tested. But all this 'hiss or no hiss' confusion makes it very hard for people to know where they stand. Keep doing what you're doing by the way sir.
Hey big jefe hope all is well with you. I have the liberty air 2 and I also have the hiss/soft white noise when music not playing, are you having any issues with the liberty air 2?? Much appreciated gracias..
@@mrkwd I am loving this love between earphone reviewers.
Wish, I saw this review before I bought mine. Was so excited. There were sooo many good reviews. They hiss so bad. I even put my cheap earbuds in for comparison and those don't do it. Definitely returning these. I'm starting to think some people don't hear the hiss, because different individuals hear different frequencies. I'll definitely be looking through your reviews to find some new earbuds. So disappointed. 😩
Jim's Review Room mentioned the hiss too. There definitely is a slight hiss. I've sent mine back and the hiss is better but still there, but for me it's not a major issue because when I'm listening to music I really don't hear it. To me personally these are the best earbuds I've ever heard but I definitely want to check out the new 1more's.
Thanks for sharing your experience Luke, I know it'll help a lot of people thinking of buying these!
Luke MTECH I had the 1more and they are good! Not great. Sounds is good, there is no much base. It’s pretty basic!
Wow I haven't seen anyone take criticism so well 😮
Haha thanks, I didn't think of it that way!
Because they think that they are "reviewing" products.
I have, he explains himself to much, it's annoying. Just continue with the video & ignore it.
i just bought the Anker Liberty 2 Pro and they hiss a lot... so angry
I think you give an honest review and it’s nice that you did a follow up. I owned the Liberty 2 Pros for about a month before I saw your first video talking about the “hiss”. I realized that it was present the whole time but I only really noticed it prior to playing audio and after it stopped. Kind of like it’s activating and deactivating. During playback I didn’t notice a “hiss” and the sound, to me, was really nice and enjoyable. I’ve tried the Jabra 75t’s but was not impressed with the sound for the cost of those ear buds. Either way, I think you have a valid concern but for me it doesn’t affect my listening experience.
Keep giving your honest opinions and doing what you do.
Hi brother you mean liberty 2pro sound better?and the bass which one stronger?hope you reply thx
Anyone who has read reviews on Amazon knows that audio hiss is a major problem of the both the anker liberty pro 2 and anker liberty 2. Thank you for being an honest and thorough reviewer. Watching your review has saved me the hassle of purchasing these defective earbuds and subsequently deal with the returning process. Kinda makes you wonder why most other major review channels decided to completely ignore this problem . Subscribed.
I confirm - there was also a hiss in my Liberty 2 Pro (I sent it back). I compared these headphones with my friend's Edifier headphones - you can clearly see the problem after turning on the Prefect Piano application (Android) - the hissing in Souncors starts after starting the application (without touching the piano keys), while in Edifire there was absolute silence. Hissing is also heard at minimum volume. Sorry for the poor english.
My guess (and it's only a guess) is that the hiss is at a frequency some people can hear, and some people can't. That's what would make the most sense to me. If they had earbuds that didn't have the hiss, they would've sent those. So I'm guessing that all the earbuds have the hiss, but only some people can hear it.
It’s like being color blind but in the sound department 😂
Honest Review!! Unlike other reviewers where every review sounds the same or positive, which makes it harder to decide what product is best.
Yeah, I have the hissing issue as well, which sucks because I really wanted these earbuds to be good (I mean they are, but this problem is really annoying), I did get a replacement supposedly improved, but I still had the same amount of annoying hiss.
One thing's for sure, their customer service is amazing!
I bought the Anker soundcore life P2 and they have this exact problem! The left earbud has a prominent hiss, and when I remove the left earbud the right earbud has a lower hiss. The right earbud volume is also much lower than the left one. I know I have the life P2 and not the liberty 2 pro, but I thought I was going crazy until I found this video, now it makes sense! The left earbud is probably an older one that has the hiss and is louder, and the right one is probably a newer version that has an overall lower volume and therefore less hiss.
Well, perhaps they've been updated because I just purchased a pair of these and there is no hiss at all.
They have the best audio quality I've heard yet in any earbud under $300...bar none.
Very glad that you pointed out this issue. Only you did! This is what I've been looking for before making the decision of purchasing. Thank you so much.
Man that's a lot of efforts there.. appreciate it. I was gonna place an order for Liberty 2 pro. I'll look for soundpeats
Great review man. Finally someone that thinks like I do. I don't accept the audio hiss and the bandaid fix that is trickery and not really fixing but only adding a new problem which is limiting volume. So many people that dont know any better get fooled. There are bluetooth /signal issues with most products I've tried and from many companies, not only Anker be it noise, compression or limited sound quality for whatever reason. This is why I have to stick with the Fiio BTR5 using LDAC wireless with my LG phone and just plug in the earphone or headphone I like. Using a high quality DAC, headphone amplifier and wireless connection is imperative to great audio. After that comes picking a headphone that suits your taste in sound signature. To try and get that all in one is nearly impossible for me. After my recent audio experiences with Anker I told them I'm not getting any more of their headphones until they reach minimum hifi levels. Recently and before I bought the BTR5 I tried the Soundcore Life Q10 which sounded like it was using a trickery processing type that reminded me of simulated surround sound. its got a wow factor when you put in on your head but quickly I notice songs I'm familiar with sound unnatural and simulated with surround type reverb! Its subtle but that's the trickery. I just cant believe people use these things daily and are listening to such weird manipulated audio without realizing. I could be wrong and maybe its something else with that audio chip their using that is causing the weird sound but its how it sounds to me,
I’m glad you have done a follow up video with a very balanced response to the comments in the original video.
Hi :-)
I believe this is just electrical white noise, every amplifier that ever existed has it whether your ears can hear it or not. The balanced armature driver directed into your ear exaggerates that a little and that's what people hear as hiss. Some people are more sensitive to it I guess. Most ear buds have only a single driver unit that handle the full range frequencies so you would not notice it as much as the high frequencies are muffled a little but every BT earphone has this to some degree, I own dozens and can hear a little white noise in every set with the volume cranked. Most BT ear buds don't have dedicated balanced armature teeters for high frequencies like the Liberty Pros 2 do and that exaggerates the white noise a little. My opinion is that they are still the better sounding BT earbuds for listening to music and reproduce the full range and sound great I don't notice the issue at all and I have 0 issue with them. I love mine and purchased an extra set recently.
i have 2 bluetooth tws, one has hiss one does not which means its not a universal thing. the weird thing is, the one that hisses actually cost a bit more than the one that does not which is kind of weird. both cost around $30, much cheaper than anker one.
to get rid of this hiss . The whole patch have to be send back to factory ,to have a certain chip to be replaced . Anker is not the factory. So by doing so anker have to pay extra and recall all hissing product .but I think there is a deeper reason for this . There must be a deeper problem in the manufacturing proceed .So final story ... reduce volume .They win , some people don't mind .
Thank you for your honesty, its a rare thing for product reviewers on RUclips ❤️
I had the white ones for 2 weeks now. I did know about the issue and have tested them thoroughly. No hiss at all. Paired with Galaxy Note 10+. Sounds amazing.
I just bought these at a massive discount but honestly it's really nice to have someone being honest about it. You got a sub out of me. Although the first part of the video I was ready to click off, I'd suggest hitting with the harder facts first because I came from the other video and I don't think many people stuck around to see that you are genuine. Hopefully, the pair that I ordered doesn't have it but for 33 dollars it's my better bet for the time being because my dogs ate 2) 200 dollar pairs in the last month. Kind of over expensive earbuds for now at least until I can figure out how to train them to eat their dog treats and not my earbuds. Thanks for the honest review.
You are absolutely correct. I have the Soundcore Spirit X2 and experience the hiss you are talking about. The sound quality is very good, similar to the 1MORE true wireless but with a deeper lows. I don’t like the hiss but the sound is good. I take them off as soon as I stop listening to music because of the hiss, wish it was not present.
when i pause this video i hear a hiss with mine in, it is there when the video plays but its no where near as noticable.
to clarify its only noticable when im on a tab that can play audio, or watching a movie, and i dont play any audio. So if i play them normally the hiss isnt loud enough to be a bother and I will probably learn to ignore it.
Great video. It is sad to hear that Anker did not fix the issue. I was planning to buy a pair of Liberty 2's but decided to not buy after your first video. Instead, I ordered 1 more stylish. I hope they will be good. Thanks for your honesty.
Yes, I'm disappointed as I had originally heard so many good things about the L2Ps and I really wanted to love them. The 1MORE's look sick, hoping to try them myself soon. Thanks for watching!
@@mrkwd You actually tried 1 more stylish out. You even have a review video.
Damn, I love your reviews whole-heartedly! Well done and please keep doing these.
The figure of defective units is definitely much more higher than 1%. I, from VN, have returned my liberty air 2 to the maintenance store 2 times for battery and sound issues
I love the sound quality in the buds but I can't ignore the hiss, returned mine. Hope they fix this in later Liberty Pro
I got mine about a month ago and they’ve been absolutely perfect. Best truly wireless headphones I’ve owned!!
Listening to this from Liberty air 2 with the same issue. :)))) 1% seems to be strong with these ones. I think I'll hope for a replacement and if it doesn't work I'll get 1more buds. Hopefully you've got a review of them too. Great vid!
Anker reached out to me explaining that their “updated” version had fixed the hiss and microphone issue. Was almost convinced until I saw your video. Thanks a lot for your review. You just saved me 130 bucks! 😊🇱🇰
No hiss on mine and the knew firmware update holy shit it blows away my $250 Powerbeats pro and my Sony and my bose .i sold all 3 and stayed with my liberty pro
Too bad. You’re missing out. They’re excellent.
No his for me. I picked up a pair off Amazon for £75 last week in a flash sale.
I was worried, bit its hardly a gamble given Amazon returns.
Hey , Jim’s Review Room also mentions the audio issue you mentioned. Thank for the honest review.
Yep, mine hiss. It isn't massively heavy but it is there. I watched this review the day after I received my Nuraloop and I have also tested against my Sony WH-1000X M3, neither of these hiss. Silent until content begins and silent immediately after. The Soundcore Liberty 2 Pro have the hiss which seemingly coincides with the drivers kicking in and powering down pre and post playback.
Your not alone man. I bought the liberty 2 pros, they had hiss and the right earbud didn't work. Returned them and treated myself to the liberty 3 pros. They hissed as well.
Edit: L3P no longer hiss and are some of the best sounding earbuds I've ever had. ANC isn't amazing tho, on par with some 50$ earbuds with ANC. Not why I bought them though, just wanted the best sound out there.
Perhaps some people don't hear it as much due to the frequency response they their ears hear. Or maybe even the eq settings that are being used.
i also have very loud hiss on my liberty air 2
hey i have just bought mine 3 days ago. can you try playing pure sinewave generated frequency at around 8khz.
mine gets horrible at this range from 7khz to 9khz.
@@shardx191 mine also... do you have hiss on yours ?
Just received mine, they hiss. Instantly contacted support, waiting for response.
Anyone saying there is 0 hiss is either not hearing it, lying, or in denial. I'm 2 pairs in as well and both hiss. My second unit indeed had quieter hiss, but it's still very much there. That combined with the abysmal mic quality certainly damages the overall experience. They are still good headphones. But combining that with the fact that they WILL NOT replace a single defective part, I wouldn't purchase again. You loose or break the case or one earbud, you have to buy a new pair. That's a serious problem.
Hell impressed by your work and your credibility when talking about TRUE & FAIR Reviews! Hats Off! 👏
I got an updated pair and I think I'll keep this one. The background white noise/hiss has been reduced to a level that I can live with. It's there if I listen for it, but it's nowhere near the loudness of the first pair I got. As for whether there's a volume reduction in my new pair, I think there is, but it's only slightly.
Using L2pro for last 10 days. No hiss at all. I am so satisfied with sound
@@p3tzl washed..Still no hiss
You just gained a new subscriber. Thanks for your honesty and integrity.
I just bought a pair of the pro's. The first thing I noticed was the hiss.
I Believe you bro!!! You are right!!! cause I've seen other reviews and comments about this same hissing problem!!!! SHAME ON SOUND CORE ANKER!!!!! Thank you for Your Honesty!!!!
Frank Coleman 😊
I only hear it when I get a notification but never during music, calls or nothing playing at all. It's maybe a second if that. Not w big deal or something that makes me want to return them
If u dont hear it doesn't mean it isn't there and color the og sound , maybe people that doesn't have high end headphones cannot perceive the difference
Okay so found something really interesting, if you try listening to your music with "Hear ID" on you will not experience the "Hiss" sound. As soon as I switch to different audio profiles I can hear the hissing sound. Do let me know if you experience the same.
Btw thanks for the FINAL UPDATE FROM ANKER AFTER after this video.
its defferently quieter! wow! still there tho but wow way better
I am releasing my review of these tomorrow and hadn't noticed a hiss. Now that you've mentioned it I'm testing them again, and if we're talking about the same thing then I wouldn't describe it as hiss, and I certainly wouldn't describe it as "hissing like an anaconda". Hiss is far too strong a word, and I imagine that's why other people are struggling to agree with you. It's more like a very quiet analogue tape sound, and it's a sound that I think is audible in most earbuds, I can hear the same sound in my Google Pixel buds for example, but only a split second before the music kicks in, which makes me wonder if the sound is actually present in ALL earbuds, just that others are better at muting it until sound is playing. I'm not saying there's no noise, but either you're exaggerating when you say "hissing like an anaconda", or we're hearing two different things.
Hey Paul, you're correct - it's 100% over-exaggerating for effect when I say 'hissing like an anaconda' because of course, they are not literally hissing like snake 🐍! But I simply use that tongue-in-cheek phrase to highlight that the L2Ps are one of the worst hissing/audio static true wireless earbuds I've ever heard. For example, if I had to rate all the buds I've tested out on a scale from 0-10 (or silence to anaconda-level, if you will) in severity of hiss, the L2Ps would be a 10.
Hiss is not a word I decided upon myself, if you Google 'Liberty 2 Pro audio hiss', that's what people initially referred to it as, so I continued to refer to it as that. Even analogue tape sound is referred to as tape hiss! That exact sound you're referring to is all I meant - some people prefer to call it audio static, but it's all the same thing.
Yes, there are buds out there with hiss, but there are also tons of buds with zero hiss. Even in buds which are much cheaper - hence why I personally feel that any level of hiss, especially during playback, isn't something consumers necessarily need to tolerate.
You have to bear in mind that in the original units of the L2Ps (I pre-ordered mine and got them on day 1), the audio hiss was noticeably worse than those released recently (the overall volume reduction reduced the hiss). So my original opinion may seem over-exaggerated if you're listening to a pair of L2Ps purchased recently.
Either way, thanks for coming over to ask me! Look forward to watching your review - I just subbed as your channel looks awesome 🔥
@@mrkwd Thanks dude, and I fully appreciate exaggerating for effect. I am about as over the top as it gets 😂 I guess I can't think of a better word for it either, it's just that "hiss" is a cold word, whereas I think this is a warm sound and actually quite pleasant, it might sound odd, but I kind of like it! I didn't notice it at all until you mentioned it, but I wonder if subconsciously it was one of the reasons I really like their overall sound.
Many engineers mix a little analogue tape sound into their music intentionally to give it warmth, there are plugins devoted to recreating this sound for digital recordings, because without it a digital recording sounds soul-less and flat. I've personally used a plugin called J37 Tape Saturation by Waves on my bands recordings as without it the record just sounded sharp and ugly, I kept finding myself increasing the bass, and dropping the treble, and adding de-essers to instruments, but nothing I did sounded right until I just added a VERY subtle amount of tape saturation to the master channel. Another odd effect that distortion has is that instead of hiding sound, it can actually improve clarity, it makes me wonder if the noise we're hearing is a byproduct of something they're doing, or if it's an intentional effect.
The other thought I had, was that the internal components of these buds are lined up very differently from other buds, the daft name they've given it is Astria Coaxial Acoustic audio, but what they're actually saying is they've made the sound clearer by having the tweeter and the woofer both pointing straight at your ear, I wonder if the noise is always there in bluetooth earbuds, but is more evident because of the way they've lined up the little speakers.
Each to their own either way. I love these earbuds, but everyone is different. Your channel also looks awesome, I admire your honesty and I'm amazed at how well you've handled the criticism in your comments section. I have a sock puppet specifically for calling those people names 🤣
I had the hisssssssss. Drove me nuts I had to return them. I even wrote a review on amazon.ca because of it.
It's too bad because they did sound good but without the hiss would have sounded amazing! I also didn't find them the most comfortable.
You are bloody brilliant, taking that flak on the chin. The video is very honest and you are very genuine. Thanks, keep it up 👆
Haha thanks so much Tel! 🔥
I've got the liberty 2 non pro's and there is a slight hiss as mentioned but only when there's nothing playing. When listening to music or podcasts I don't hear it at all, even at low volume. I could care less if there's a little hiss when there's nothing playing. Different story if the hiss was audible during playback. That said, want to sell the original pair? I'll buy them from you, lol. I wanted the pros, but I couldn't find them anywhere and impulse bought the regular ones.
I will subscribe based on this single video itself.
Got mine liberty air 2 last week and notice the hissing sound the first time I used it. Send it back right away and this is their responds:
"According to our testing, there was no hissing sound heard by the technician. We suspect that the hissing sound can only be heard by the young generation like you where people with some ages like our technician didn't suffer from such issues. As such, replacing a brand new earbud for you won't solve the problem. You can either choose to refund or get back the original buds you sent us. "
REFUNDED
Just received a second liberty pro 2 it sounded amazing, no white noise hissing when it comes to pausing the audio with no volume, calling didn't have that issue. When I reused it, the issue came back.. this time instead of the white noise on my 1st liberty pro 2 was 2 seconds. My replacement is now 4 seconds which added 2 second and I am annoyed that I thought I did not get a defect but within a few hours now it does not work well.
I thought these 2nd pair would be the improved 2 iteration of the Soundcore liberty pro 2. I have bought Anker products like the usb type c, power banks and now the earbuds. Its very discouraging getting a 2nd product that i thought was not a defect without any hissing for a couple of hours when i first received it. This is my second pair and i went on the sound core forum on liberty pro 2 and many consumers who bought your product has white hissing noise. I do enjoy this, but if i return this. There is still a chance that i will get the white hiss unit. I don't really want to waste more time and have hope that i will get a good liberty pro 2
Was about to pull the trigger on these...not anymore!
Man, i have 2 pairs of the liberty 2 pro's (black) and neither one of them have even a slight hiss....NOTHING. I did hear about the hiss tho from other reviewers.
I DID however have problems updating firmware on my first pair i bought that i sent back for a replacement. Then the replacements updated to the 1.22 firmware like the first pair should've . Is your firmware updated?
I wonder if the voice assistant feature is part of the reason for the hiss because the way I have both of mine set up is that the double press on either side moves tracks forward and back and then the long press for one or two seconds is volume up and down. I have no button control for voice assistant because I'm not going to ever use it. Maybe that voice assistant feature is messing with the hiss? I don't know.
I think thats actually a good theory! Would totally make sense to me as voice assistant has already messed with some of my former haedphones..
I've ordered them a few days ago, they should arrive today. I'm gonna test that and wirte another reply then :D
@@lourobin5927 yeah let people know. I hope they check out fine for you😎
well... the suspense is killing me!
I got mine today, I'm waiting for them.. this suspense is killing me
idk whether to get them or the liberty 2 air the hiss scares me
I had the liberty air 2 for a year with no issues, lost them and got new ones today, the hiss is ear piercing and so annoying i gotta return them 😣
I know this is an old video but found if you set the buttons on the buds to long press works the volume, if you then lower the volume it reduces the hiss, and I'm not taking the piss lol. It reduces the volume of the buds themselves independent of phone volume you can then increase the phone volume. Hiss is still there but a little lower. I'm in the process of returning mine. So just a tip for anyone else.
Thank you so much for the honest and informative review and for being unwavering by commenters' and Anker's responses. Your review is excellent and very helpful in my decision about Anker Liberty 2 Pro. Keep up the great work!👍
Well done, there's a design flaw with these guys and Anker are giving us the runaround, complete time wasters, I'm sending mine back. Here's the worrying part, what do the 10 "top producers" sponsoring the L2P think...assuming they've even bothered giving them a listen !
Three units later for me and all of them had this hiss. I think I'm done with Anker altogether, maybe if they release a Liberty 3 that doesn't have this issue I'll give them another go.
You are definitely on to something as many "real" reviewers have reported hissing and sound issues with this these earbuds, and so many "other" (i'm polite here) reviewers have been saying they are the best under $200 are dishonest as we know now from inside sources , soundcore themselves, that they offer $8,000 per 200 units sold through affiliate links to reviewers, that is is $40 per unit , considering that some real audiophile reviewers have said that these earbuds sound completely off , says a lot about why soundcore is so shifty about it .
good on you fella 👍
Mine have had hiss since I got them. I mainly use them for RUclips videos, so it's never bothered me too much until today when I compared them back and forth to my new Galaxy Buds Pros and it's all I can hear now. I'm gonna contact Anker to see if they can replace them.
Got mine today and didn‘t have audio hissing or white noise. I heard and read a lot of reviews on youtube and amazon and was really hesitating to buy them. After I was still disapointed from the airpods and earpods pro, I decided to give it a try. I‘m glad that I didn‘t have the problem in the situation you described.
So far I don‘t have much experience with the earbuds but I really like that they stay in position and have a solid and controlled bass which I really missed withe my airpods pro
Everybody experiences things differently, the most important thing is that the issue is resolved for anyone who is experiencing that issue
I think those who say it doesn’t have hiss just aren’t able to locate it but it’s still there. Maybe they’re sound- blind . 😂
I watched your review a while ago. I also contemplated buying these for a long time. I ended up buying them. I hear the audio hiss before, during, and after playback. I listen to a few different genres and some songs drown out the hiss.
1:1,000,000 chance, like it's possible but highly unlikely
These are amazing....they are so clear you get white noise, but can be tuned perfect if you mess around with the EQ's ....
I believed you! I had the same issue with the hiss! Anker was nice enough to send me a new pair..the new pair still had a hiss but it wasn't half as loud.
Kudos to a very honest review. It shows you know what you are talking about and are confident enough to stand your ground even while facing such a huge amount of flak in the comments. Personally I am still very interested in these headphones due to the separate drivers covering the full audio spectrum. Its like having 2 way speakers instead of a full range. We know that there is hardly any comparison even with quality full-range drivers. I have experienced this type of hiss you describe quite often and I have a feeling it also has something to do with the audio codecs as much as the hardware itself. Even original music is sometimes recorded at source with hiss. I personally listen to such earphones at high volume during a workout so the hiss becomes a non issue. There is a way Anker could reduce it by rolling off the high end of the spectrum at the amplifier output, but that would mean that you would not be hearing the full music spectrum. If I had a choice between suppressing the highs or enduring a little hiss, then I would go for the hiss every time. However I'm posting this comment only based on my audio experience in general and without having heard these headphones. So I will update this post right after I order my headphones and having run them in a bit.
Thanks again for your refreshingly honest reviews. I am now a subscriber. :)
Download the app and set the sound to your own ears, your review has not touched the surface of what these buds are capable off,
They are absolutely awesome.
Is there any TWS without hissing sound? I really need one of them. 🤦♂️
they are.. i have a 10$ tws and no hiss, friend has huawei airbuds and also no hiss at all
Damn, almost bought these. Went with the Buds+ instead and have no regrets but shame I didn't find your channel sooner. Have a like.
I got mine yesterday I noticed a very very slight hiss which is not noticeble but when I hear the same song on Amazon prime music I hear no hiss but I hear them on Spotify don't know it it's related to codec but I can definitely say one thing that it's sound quality is some next level because I own a wide range of headphones like beats solo wireless 3, liberty 2 pro is like much better than everything and also if you set up hear id you could hear very less hiss
But I am very great full for your honest review really honesty is very rare among RUclipsrs now a days so keep up the good work brother 😍
Good job on the review and follow up. Appreciate your honesty. So much so, that you just got yourself a new subscriber. Keep up the good work
I believe in you, because I had same issue on my b&w px headphone. Such a well known brand but unfortunately I received the defective set. When asked for exchanges, they rejected me because they thought I was being fussy. It was so frustrated, and helpless because no one willing to believe me. Until today, I have never worn it again.
I believe you and I'm also disappointed with some of the other reviewers that ignored the problem. Although Flossy Carter did mention this issue but he's the only one who did. Thank you for your reviews I'm going to avoid these earbuds.👍
Some people's ears may not be able to hear the hiss. I know that from years of shooting, I cannot hear certain frequencies at all. Could be one theory as to why some reviewers are not hearing the hiss and some are? I have old Anker Liberty Zolo wireless earbuds and still love them to this day after owning them for over a year. I only paid $50 USD for them. Good review, I never had a doubt in your honesty. 👍
Just got mine today and ran them through all the test with music on low and high volume. Changed stations and no hiss sound at all. So far so good. Out of this world. Great sound and bass. Mine came from Amazon.
Joe Patrick did you get the white ones?
Fishing with Gabriel no, I did not get the white ones. Had to return them because phone to phone communication was really bad on both ends. A lot of cutting in and out.
Joe Patrick dang that sucks
@@FishingwithGabriel the white one still has a hiss
Mark thank you for your honesty !! I had the earbuds and I returned them and got something else !! Cheers man ..
Now when you say it i can notice that hiss 1 second before and one second after I press play and I can hear it slightly when the music is playing unless I have full volume
It's the qualcomm cvc noise cancellation issue.
I bought a jbl tune120tws and my friend bought a soundcore liberty air 2 a few days ago during online discount sales. The soundcore feature list made me regret buying the jbl. But then, I played a few songs on both back to back connected to same device, tested on 2 devices.
The JBL sound quality is just way better, no hiss, clear crisp sound, better bass response.
My regrets are gone. Don't mind missing a few features in exchange for sound quality.
It's March 2022 I just bought a pair and they do have a hiss right when I press play it's a very audible hiss but it stops after a few seconds and then starts again when I pause the video I can't hear it during playback no matter how low or loud volume is
My pair also hisses, but I didn't notice it until I watched your videos today. :P On my pair it's so quiet that it hasn't bothered me at all up to this point.
I wonder if this hiss issue discrepancy between listeners is due to some folks having tinnitus. Sound engineers and musicians have spent their lives around music (some/most of it loud) and suffer from varying degrees of hearing loss. I'm curious, if mrkwd has unadulterated ears (no basement punk shows) and can pick up the 'background noise' better.. I wonder what the frequency is. If it is quite high, chances are folks with any hearing loss whatsoever may not pick it up.
I have a set of the liberty air 2 and I'm having the same issue...its white/pink noise in 5he backroom before music starts then it's not super noticeable but when music stops then the white.noise is there again...I'm getting ready to contact soundcore myself..I own a pair of 20 dollars TWS Enacfire g20 and I have no white noise what so ever..
I got mine for my Birthday yesterday, on the barcode it titled "refurbished" and the Hissing/White Noise is very noticable as explained of many Users at the Beginning of a Song or Video, and when paused it stops after like 3-4 seconds because the Earbuds go in Stand-by-Mode. Pretty sad...😅 My Brothers owns a Pair of Liberty 2 (not Pro) that don't hiss at all. Gonna return them and see what i get in return
I'm glad i didn't get unlucky like you i hear no hiss what so ever and love my pair still at the same time I respect your opinion and honesty with your personal experience
Thank you for your honest review Mark.! Good looking out for us.
I have had mine now for about a month. NO HISS.... I've tried connecting to various sources (phones, TV's) ... still No Hiss... and just in case I am personally deaf to the hiss frequency, I had both of my sons try them and they didn't hear any hiss either. As a result I am happy to say the sound is fantastic. I decided to roll the dice and buy these a month ago as they were on sale for only $149 CDN, and if they had hiss, back they would go... seems I may have gotten lucky.
I have purchased a unit of the anker soundcore life dot 2 and for a couple of days I tought I was developing tinittus. The "hiss" is horrible and lasts for up to two days from a short session.
I watched many earbud review videos and had just ordered the Anker Pro 2s for $129 Amazon. But as RUclips knew I was watching Anker videos so right after my order I see your video. I wanted a trouble free quality sound and my main source Flossy glowed about them. Bottom line your thoroughness moved me to cancel and change my order to the Jabra 75ts. I have more earbuds and headphones than any one person needs but my last purchase was Soundpeats dual driver which I kind of liked for the $. I hardly use them as I use my Bose headphones on lockdown. But I tried them a few days ago and 1 driver is shot. Bought them direct from China so I’m screwed. Thanks for your persistence. I would have bought the Sony’s but their size concerned me for the price. Many reviewers like the Jabras, hope I like. Sound quality first for me. I like Anker’s products overall, hope next time their great!
I wasn't playing and I just got the Sennheiser Momentum True wireless. Good God . I love them .. I get and understand budget but hands down they're the best . Excellent review .. keep em coming . May be looking for a backup for work
@James Torres,
Those sound pretty great and fit my ears absolutely perfect too, but I don’t know what “hands down” means. Some others sound as good, including these Lbrty2Pro if you get the personalized hearing right and avoid the so called “hiss”.(I have yet to notice that)
But the problem with Momentum is that the charge case drains constantly and doesn’t last long enough to serve it’s purpose effectively. At first, it doesn’t seem to matter much. They do sound so good and have that great ambient mode that you’re not worried about the battery. Later on though, it gets annoying when you realize how often you have no battery and need to recharge the whole thing. Jussayin...
That’s my experience anyway.
I'm sure I'll encounter this problem .. I follow what you're saying and for me the sound is the payoff. Thank you and I appreciate your input .. outstanding reviews
@@jamestorres5582 300 for that thing and u still have to do maintenance/manual repairs. LOL no ty
I really liked your honset review + the update video.
I bought these yesterday on sale on Ali express for about 100$ after watching a lot of reviews praising them and one even saying they are on par with the Sony's wf-1000xm3 and the Sennheiser's Momentum TWS 2 audio wise.
I did watched a video by Jim's Review Room on these and he did mentioned a slight hiss but only low volume levels.
That sucks you had that issue mine fortunately work great and I absolutely love them, great sound and the app provides some good features. Keep up the awesome work
Ughh I really was hoping it was an isolated incident. Unfortunately, mine do have a noticeable hiss as well. When I emailed to try a second pair, they replied that mine are actually the newer version and basically the experience I have is what it is. So it's not going to get any better until they put a new one out. Sending it in for a refund. Recommendations for something in this price range? I enjoyed my Sabbat E12 Ultras, but was hoping for something a bit less muddy but still good bass this time around.
i got my l2p just 3 days ago. my issue is that when low freq music is played it covers the hiss. now when i play something like 8khz pure sinwave generated frequency i feel that the hiss gets louder and i cant hear the note purely. can someone confirm that this issue is that same everyone is facing or if its something thats the fault of my specific product?
the issue lies from about 7khz to 10khz.
in your testing did you try them on different devices?
Thanks for the honest review, I bought the Pxc 550 II from Sennheiser but they have an audio hiss. Returned and bought the Sony xm3 and going to buy m50xbt
I read somewhere it could be iPhone problem, can you discount this has i have Android and if true want these buds, they seem to have everything but are ruined by this ????
My just purchased Liberty Air 2 has the exact same problem as described. Cant wait to read what their support team is gonna say about that.
Wow, I wish I would have seen this before buying these. They absolutely hiss, and quite loudly. If you’re listening to music it isn’t a big deal but I listen to audio books with these and it sounds like a garden hose is spraying in the back ground. It’s incredibly distracting, these will be returned.
