Very practical topic, thank you for making this contect. 3 years has gone since this video, Caleb, have you found some better transmitter recently? New updated video would be nice one as this is still very relevant topic.
Philip Bloom I can confirm the Hagibis in fact works perfectly with an aptX Low Latency headset. Avantree pairs well together just testing it out now & impressed with results!
@@dslrvideoshooter No you're not! LOL. But we don't mind. Keep providing us with links to innovative products to help our production value and we will keep right on watching.
Do you know what would be ever better? If camera manufacturers that sell those $2K+ cameras would just put that small BT chip with aptX (that cost less than $5 on aliexpress) inside and simply allow users to monitor audio wirelessly by directly connecting to the camera. I mean, they could even go crazy and have like a delay adjustment in the menu for those with BT headphones without low latency mode. That way they won't even need to waste space for that pesky 3.5mm headphone jack for monitoring (which they don't bother to put into most cameras anyway), and also they would be able to put this feature even in very compact bodies like Sony RX100 lineup. Imaging living in that world! Oh, one can only hope… In any case, Caleb, thanks for the video!
Do you know why? Because monitor headphones are called monitors not headphone for a reason. First of all latency, bluetooth is digital, encoding and decoding take time. Second is digital, bluetooth connection is slow and no way match the frequency range and transmitting rate of analog, thus wont fully represent the full spectrum of the audio recorded thus not monitoring any more. Bluetooth 5.0 will certainly bring new players to the table but 5.0 is relatively new so it takes time.
Nguyễn Anh Quân Don’t want to be too harsh, but are you one of those people who thinks vinyl is superior and gold plated hdmi cables are a must have? Dude, even 15+yo ancient BT2.0 can transmit at the rates of 2Mb/s! Top quality aac/mp3 needs only 0.3Mb/s for quality that is indistinguishable from uncompressed wav files, what frequency range are you talking about? I watch videos everyday with my AirPods and have 0 problems with latency, damn, I can even use them in GarageBand for melody sketches and there and only there, for input, you start noticing delay and time lag, not for output which is what we’re talking here about. Manufacturers don’t do it because most of them are lazy non-innovative cash grabbing monstrosities. I mean, take a look at pro-video market. It’s smaller companies like Blackmagic who deliver amazing and revolutionary products nowadays, not Canons of the world.
@@Frytech Dude, first of all, consumer technology is trickled down from professional technology. I'll talk from consumer perspective. A7SII XAVC codec record audio at 48khz 16bit which is approximately 1.5mbps. APTX LL codec data rate is 420kbps, which is one third the recording rate, so listening to the audio transmitted via APTX LL codec you are actually listening to one third of what being recorded. Defeat the purpose of monitoring, how is this significant? Have you ever heard of the problem where the picture on camera screen differ from what you see on your monitor? Do you want to listen to a record thinking yes everything is fine only later to realize there are some weird sound that had been filtered out by the encoding and decoding process? Beside, APTX LL codec is licensed by Qualcolmn, require both transmitter and receiver to be certified to work. Do you want to pay more money for the camera then pay more money for a headphone to use it? How many people use bluetooth headphone? How many of them are APTX LL compatible? Airpods are not APTX LL compatible I must remind you. They have latency around 120ms, look it up if you dont believe me. Moreover, BT2.0 transmits at the rate of 0.7Mbps, bluetooth 4.2 transmits @ 1Mbps, BT5 transmits @ 2Mbps so get your fact straight. Secondly, watching video on youtube and using apps via bluetooth headphone is different from monitoring live recording. The system (phone, pc) compensate for the latency by actually playing the audio ahead because they are able to do so. Want me to prove it? Instead of listening directly via your phone bluetooth, plug a transmitter in via 3.5mm port on your phone, then connect your headphone to the transmitter and tell me if there is latency or not. Thirdly, there are Fujifilm, Blackmagic, Sony, Canon, Nikon, Panasonic, 6 major players in consumer market right now and they are very competitive. If this idea is that necessary and lucrative and so easy to do why none of them have jumped on the ship yet? Please refer to my second paragraph for the answer. Now let's talk about professional market Manufacturer dont do it because the consumer doesnt need it/the technology is not there yet to meet the standard. Meet any pro audio guys who work professionally and ask them about bluetooth audio to see if they're going to laugh at your face or not. Look up wireless audio monitoring system and tell me how you are going to fit that into a consumer camera body. Beside wireless audio use radio, which is analog, digital has just came into the market very recently and again they are for consumer, not professional. Blackmagic cameras are very consumer and prosumer oriented and they have their own market. Professional cinema cameras come from Panavision, RED, Arri. Professional broadcast/ENG camera however dominated by Sony, Panasonic and Canon. Canon however started the DSLR video camera trend in 2008 with their 5D mark II so dont say that they are not innovative. What I'm trying to say is you are a consumer and have consumer mindset so clearly you want this and want that and think it's easy to do so but actually it is not. Technology has always been developing and has it own limitations. One day when the technology is there you will see it. There are a lot to talk about if you are interested I will tell you more about bluetooth audio in general and why manufactures dont include them in their camera to be specific. I've watched some of your videos, you're clearly very biased and need to work more on your knowledge. Calling people fan boy when being called out is not a way to develop a news channel. Comparing a lossy audio format to a lossless uncompressed wav format and telling they are equivalent is ridiculous, yes they are equivalent if you are listening from a 30$ headphone, or... bluetooth headphone. It's like saying that an 1000$ iPhone can shoot video equivalent to a 50000$ ARRI. Yes it is equivalent if you're watching from a 3 inch screen, via RUclips, at 360p.
Haven't finished watching but I have to say this is a very valuable experiment. It's not just for cameraman, I wear the headphone when playing my digital piano and due to the latency I can't use bluetooth headphones, not that I expect to find a solution in this video but this will help push the industry in the right way.
Your Headphones need to support AptX too! Otherwise, its gonna use some old protocols with high delay. Then, a lot of those AptX transmitters wouldve done the job.
No doubt, this guy is another one of the most beneficial content creators on RUclips and his channel deserves more subscribers. Keep up the fantastic work Caleb.
This was great overall, but minor complaint: For your "low-latency" choices, you suddenly switched from previewing via camera output to using the MixPre-3. Given your past findings testing HDMI monitors and such, it's possible the headphone jack on the camera is adding to latency where the MixPre-3 doesn't? Not sure, just felt a little odd to suddenly switch which output you were using, even if the results are the same. Also the MixPre-3 has BT but doesn't allow monitoring from it. Fail.
Impossible to miss 30 seconds to give you a million thanks for this detailed totorial of great help to choose a decent auidio setup among thousands of options, you saved my time friend, thank you!
Bruh wires are 2 steps away from using pigeons to monitor audio, it's about damn time we start using air for more than breathing. Excellent video as always Caleb, pleasure watching!
HOT TAKE - I actually like the latency as it separates the lives sound that might be getting to your ears from the sound that your recording, which I have found to be useful in monitoring audio quality and picking up on issues. It does mess with your head a bit after a while though....
This was literally a feature on old professional analogue tape recorders used on film shoots, and it's exactly how traditional film sound recordists would monitor the audio. I imagine the newer digital equivalents have a similar feature. I'm personally sold on the cheapest version for exactly that reason.
02:40 Latency on monitoring audio for video is not a problem, in fact on some set ups it's actually a feature! it's "called confidence mode", and on old Nagra tape recorders it was a setting that recorders would use, as you could separate the headphone sound from any actual sound creeping in from the real world. [edit] so I watched the rest of the video and latency is the only thing tested here, I guess because it's a quick easy thing to demonstrate. There's no mention of audio quality, range or battery life, which are far more important issues.
Calab, AptX will only work with compatible AptX headphones, otherwise they will always be latency Im betting your BT headphone are not Apt X compatible
I think the Taotronics device would be best bang for buck. The issue was that your headphones don't support APTX Low Latency, which is the real reason the combo pairs do much better.
I've tested latency with wireless LAVs if you want to know, as it might apply to headphones to. So the thing to consider is also the DISTANCE. It's very important. So when you have an Audio Cable, electrons move pretty close to the speed of light, so you'll get that audio almost instantly even if you have a 60 foot cable in between the source and your ears/recorder. However, I was very intrigued to find out what the Speed of Wireless is (as there is very little info online), and after some calculation I found that it is Double the Speed of Sound, meaning that a person talking into a LAV far away will reach the camera 2x Quicker than his voice propagating through the air and into a Shotgun Mic mounted on the camera. But wait, there's more... Although that's the actual speed when the signal is sent, it still needs to process that sending and receiving (it doesn't happen instantly), and I measured this LAG as being equivalent to about 1m (3 feet) of sound speed. So therefore, to give some examples, here's how the sound travels to your camera/recorder (either via air with the speed of sound or via Wireless + Lag) - Subject at 1m Wireless: 1m LAG + 0.5m Transmission - Subject at 1m Shotgun: 0 Lag + 1m Propagation -> So the Wireless is actually behind the Shotgun on the Cam - Subject at 2m Wireless: 1m LAG + 1m Transmission - Subject at 2m Shotgun: 0 Lag + 2m Propagation -> Here they are equal. They should sync up perfectly. - Subject at 3m Wireless: 1m LAG + 1.5m Transmission - Subject at 3m Shotgun: 0 LAG +3m Propagation -> And now the Wireless will get to your cam/recorder quicker. And so on, you get the idea. That's the speed I got, of course LAG may be different depending on the product's internal chip. From what I see in your video 1 Frame of Latency = 10m in Sound Speed. So there will be a perfect Sync in your Brain if you move 10m away from the action. As for the sub-frame LAG, I say it's getting closer to that Wireless quality.
What someone else came up with was using the Rode wireless Go but pluging TX unit into the cam and RX unit into a set of headphones. It solves the BT latency issues, I gather.
Here’s my takeaway: use a cable. Thanks for the tests that proved it for me 🌹
5 лет назад+1
I know that they are three times the price... but if latency is your problem, maybe the rode wireless go will work for you... your headset can increase the volume if the output of the set it is too weak
Bless the angel that is Caleb for buying all the options for us so we don't have to. I think an update to this video in like 2 years is gunna be great because I feel like more players will be in the game at that point besides avantree.
Thank you for the sharing. Great video as usual. And I just wanna share my way to get wireless audio monitoring. I use my Rode Wireless Go as T&R because it’s nearly no delay and connection is pretty good. The best part is that I need no extra expense to get this function as I’ve already owned it. And also I can use all of my lovely monitoring headphone or earphones with it. Hope this helps. Lol
nice work.. none of these solutions look "ready for primetime", I'm disappointed we can't go Bluetooth directly camera-to-headphones.. almost more trouble than it's worth! thanks for posting, great info
Great video! They do sell wireless headphones and dongles which use the 2.4 ghz wireless signal instead of bluetooth. I found that those have almost no latency and are good for monitoring. But in the end i just went back to wired headphones because its just one less set of devices you have to charge and maintain lol
I shoot out of the back of my 4x4 in remote places and HATE dragging my headphone cord everywhere. I think the HT4189 might be the perfect solution for me because I think I can power it off my AndyCine A6, yes? I shoot with the Fuji XH1 and need the monitor to see myself so I have that giant battery just sitting there!
Did you consider using the new Rode wireless mic kit as the transmitter/receiver? I wonder how the latency is if you took a 3.5mm out from the camera and into the transmitter and then ran the receiver into your headphones.
my issue is cable banging against camera stand when recording. I eventually gave up with Bluetooth because of the faffing and paying more than i should have to. I just bought a 5m 3.5mm extension lead so i can route the cable away from the stand and back to me with no chance of it banging the stand. £8 job done.
I can see myself going wireless very soon. Nothing is worse than getting tangled in you wiring while you try to run two or three cameras and have jump back and forth between them. One accident very nearly cost me one of my lights b/c the cable got tangled in the (unweighted) light stand. So thank you, thank you, thank you for making this video 🙏 😃❤️
Thanks for this video and all your channel, it's really helpfull. I'm surprised you didn't talk about the AirFly pro, is it because it's not working with Dslr camera? I'm really looking for a solution to connect Airpods to my A7iii but i don't have any idea about the latency. Do you have an advice?
As a video shooter, I want to know if I am recording low frequency wind rumble and thus want the monitoring system that has the best audio quality. You didnt even mention audio quality.
Just what I was looking for, until I find the video is 4 years old and devices are now hard to find. Assuming technology has moved on, is there an updated version of this in 2024?
I bought a similar rx/tx kit for my C200 a few months ago. So nice, not to have the cable hanging around. Some latency, but for the price, I feel that it’s worth it 😀
Ayyy do a video for wireless HDMI transmitters? Something HDMI to micro HDMI for monitors? Just did a wedding last night wrapping a monitor HDMI cable around the lens to the camera. Such a hassle if needing to change lenses or anything really
Hey Caleb, the foxnovo 32$ option actually sounded like it was really low latency, like much better than the 4 frame latency before it. Was the audio edited properly? I am curious because compared to the rest the 32$ option with near no latency sounds like a fantastic bargain
There are 3 flavours of aptx. There is aptx, aptx ll and aptx hd. Aptx ll and hd is compatible with aptx, however if you want to have that ll feature your headphones need to support it. If they dont support aptx at all you would get sbc, if they support aptx thats what you get (and tha is your case, at bt50 have aptx support but not aptx ll) if they support aptx ll only then you gey low latency. Sorry but you should redo your test as there is huge chance all of transmiters with aptx ll would actually work fine with right pair of headphones.
I picked up that Taotronics guy a couple weeks ago so I could keep an ear on a (definitely amateur) boom operator. it might end up getting a permanent place in my bag when I'm one-man-banding interviews and trying to avoid getting tangled.
What the transmitter and receiver does is they encode the analog signal, transmit it then decode it again, this introduce latency and require computing power. Do you expect a 400$ PC to encode a video faster than a 5000$? So 4$ transmitter is not the best choice here.
Great video, thanks :) Would love to see a similar test for wireless mic systems (eg. Rode Wireless Go, Comica BoomX-U, etc) Especially since they can also be used as a makeshift wireless headphone link!
Amazing fix. August 2020 here wondering if those Avantree pucks are still the top of the line if I want to keep using my Sony headphones, or if there's something new.
Does anyone know if there is an option out there for multiple receivers or headphones? I want this for an interview setup where the cam op and interviewer can listen to audio at the same time. Anyone know of any solutions?
Great video!! I think I like the Taotronics one best, for it's size and pretty low latency comparatively, 4 frames is not bad. I also for my own preference, don't like needing the specific headphones option nor the dual puck being it's just one more thing you have to contend with, but the latency of course is really good great review and comparison!!
I actually have the final option for watching TV at night and not disturbing the rest of my household. It never crossed my mind to use it got monitoring my audio at weddings. This is a great idea. Also I might add that you can increase the audio on the headphones independently of that mixer which means u get even more juice for monitoring in a noisy situation
Great review - so after watching I decided on the TaoTronics 2-in-1 & ordered - question ; if the other end does NOT support aptX will these still work? I believe YES - just found out from the Apple Community board that iphones (and apple in general ) do NOT support aptX because they have to pay high licensing fees to Qualcomm - and Apple, despite being rich, never wants to share in paying anyone royalties - so in several hours I will see if I can use these TaoTronics 2-in-1 with a bluetooth lapel mic, transmitting to this received connected to my Canon XF-400 video camera - I usually shoot on-location with VERY loud noise background so want to capture my commentary audio ;)
This is so exciting! Here's a stupid question but could you use a headphone splitter output from the camera to multiple bluetooth devices to theoretically have a producer and cam operator both listening on their own headphones?
Dont get me wrong,wireless is the inevitable future and its damn nice not having to deal with cables tangling but my issue with having wireless stuff is its theres extra things to charge,and if you forget to charge them you cant use them. Wired headphones work all the time unless if its damaged. Theres always a give and take with everything i guess. Personally id go with wireless stuff because im so tired with cables dangling and getting stuck on things but its just extra stuff to charge.
Very practical topic, thank you for making this contect. 3 years has gone since this video, Caleb, have you found some better transmitter recently? New updated video would be nice one as this is still very relevant topic.

- Subject at 2m Shotgun: 0 Lag + 2m Propagation -> Here they are equal. They should sync up perfectly.
- Subject at 3m Wireless: 1m LAG + 1.5m Transmission
- Subject at 3m Shotgun: 0 LAG +3m Propagation -> And now the Wireless will get to your cam/recorder quicker.
And so on, you get the idea. That's the speed I got, of course LAG may be different depending on the product's internal chip.

Here’s my takeaway: use a cable. Thanks for the tests that proved it for me 🌹
I know that they are three times the price... but if latency is your problem, maybe the rode wireless go will work for you... your headset can increase the volume if the output of the set it is too weak
RODE Wireless 4 ms max latency vs . the Avantree double grey pucks’ 39 ms.
Bless the angel that is Caleb for buying all the options for us so we don't have to.
I think an update to this video in like 2 years is gunna be great because I feel like more players will be in the game at that point besides avantree.
may us know, what tripod you are using? the brand and the price
Thank you for the sharing. Great video as usual. And I just wanna share my way to get wireless audio monitoring. I use my Rode Wireless Go as T&R because it’s nearly no delay and connection is pretty good. The best part is that I need no extra expense to get this function as I’ve already owned it. And also I can use all of my lovely monitoring headphone or earphones with it. Hope this helps. Lol
If you want a cheap wireless option with no delay, an FM transmitter to FM receiver (pocket radio) works great.
nice work.. none of these solutions look "ready for primetime", I'm disappointed we can't go Bluetooth directly camera-to-headphones.. almost more trouble than it's worth! thanks for posting, great info
Do the wireless headphones or transmitter interfere with wireless mics at all?
LOVE THIS! I've had Taotronics for years. I use them on set with Avantree headphones, and on my TV to watch GOT without waking the kids!
Wait are the headphones bluetooth?
Just yesterday I was searching for the very same thing. Thanks for doing all the leg work!
After years of using the Avantree Saturn Pro, I bought the new version of the Hagibis transmitter after watching this. Hope it works well!
How long is the delay between speaking and hearing it through the receiver, please?
Was literally thinking about getting one of these transmitters today! Thanks Caleb!
I have been waiting for this video sooo long!
Thank you a lot!
A lot of VMOUNT batteries have a usb socket, so some of these options are fine when using bigger rigs. Thanks for the info !
Great video! They do sell wireless headphones and dongles which use the 2.4 ghz wireless signal instead of bluetooth. I found that those have almost no latency and are good for monitoring. But in the end i just went back to wired headphones because its just one less set of devices you have to charge and maintain lol
green tokyo I’ll have to look into those!
If you’re planning to make a follow up video for this. Please include the dji mic 2 paired with a sony a7 iv.
I shoot out of the back of my 4x4 in remote places and HATE dragging my headphone cord everywhere. I think the HT4189 might be the perfect solution for me because I think I can power it off my AndyCine A6, yes? I shoot with the Fuji XH1 and need the monitor to see myself so I have that giant battery just sitting there!
Did you consider using the new Rode wireless mic kit as the transmitter/receiver? I wonder how the latency is if you took a 3.5mm out from the camera and into the transmitter and then ran the receiver into your headphones.
Try to use a rode wireless go for monitoring audio.
It has been 4 years - is there a better option since then? Thanks for all you do.
my issue is cable banging against camera stand when recording. I eventually gave up with Bluetooth because of the faffing and paying more than i should have to. I just bought a 5m 3.5mm extension lead so i can route the cable away from the stand and back to me with no chance of it banging the stand. £8 job done.
Thanks. How about the latency issue?
I own those Avantree Pucks and they have been doing a sterling job. Just keep forgetting to charge the buggers.
Thorough run-through. Thanks, Caleb!
I can see myself going wireless very soon.
Nothing is worse than getting tangled in you wiring while you try to run two or three cameras and have jump back and forth between them.
One accident very nearly cost me one of my lights b/c the cable got tangled in the (unweighted) light stand.
So thank you, thank you, thank you for making this video
🙏 😃❤️
Thanks for this video and all your channel, it's really helpfull. I'm surprised you didn't talk about the AirFly pro, is it because it's not working with Dslr camera? I'm really looking for a solution to connect Airpods to my A7iii but i don't have any idea about the latency. Do you have an advice?
Run into this issue just last week. Bought the puck you've recommended. Well earned commission Caleb :-)
fotoworkshop-stuttgart.de thanks man!!!
Hey Caleb I’m sure you’ve done this before. But how do you monitor audio with only a headphone jack.
Great video. You can also try your Rode Wireless Go in reverse. See what that latency is like maybe?
That should work- I was able to use it as a guitar wireless transmitter, and any latency would kill that.
Keep this rolling! I'm trying to find close to zero set.
As a video shooter, I want to know if I am recording low frequency wind rumble and thus want the monitoring system that has the best audio quality. You didnt even mention audio quality.
Just what I was looking for, until I find the video is 4 years old and devices are now hard to find. Assuming technology has moved on, is there an updated version of this in 2024?
It would help if you used terms more specific than "this little guy" so we know where to find and buy them.
nice review man, super keen for this tech any little bit of freedom from wires is great and this has saved some dollars doing test so much appreciated
I bought a similar rx/tx kit for my C200 a few months ago. So nice, not to have the cable hanging around. Some latency, but for the price, I feel that it’s worth it 😀
Timely video for me as I'm in the market for this very thing! Thank you so much for your reviews. You have made my choice much more simple.
Surprised the Mpow units didn't make it into the test - you can even get 2 of them to use whatever headphones you want 👍
Was looking for a one man shooter monitoring option - nice! Will definitely look some more, but a great review! Well presented.
Your videos are just so great! Thanks for all the work you put into this.
Ayyy do a video for wireless HDMI transmitters? Something HDMI to micro HDMI for monitors? Just did a wedding last night wrapping a monitor HDMI cable around the lens to the camera. Such a hassle if needing to change lenses or anything really
Hey Caleb, the foxnovo 32$ option actually sounded like it was really low latency, like much better than the 4 frame latency before it. Was the audio edited properly? I am curious because compared to the rest the 32$ option with near no latency sounds like a fantastic bargain
I second this!
I also thought that that sounded way less than the reported latency. Better than the reported 4 frames before and the 5 frames after.
There are 3 flavours of aptx. There is aptx, aptx ll and aptx hd. Aptx ll and hd is compatible with aptx, however if you want to have that ll feature your headphones need to support it. If they dont support aptx at all you would get sbc, if they support aptx thats what you get (and tha is your case, at bt50 have aptx support but not aptx ll) if they support aptx ll only then you gey low latency. Sorry but you should redo your test as there is huge chance all of transmiters with aptx ll would actually work fine with right pair of headphones.
Can we assume that this latency problem associated with wi-fi , and does not occur with a wired system .
I picked up that Taotronics guy a couple weeks ago so I could keep an ear on a (definitely amateur) boom operator. it might end up getting a permanent place in my bag when I'm one-man-banding interviews and trying to avoid getting tangled.
Can you please tell me what's that little tripod the Sony camera is being mounted on? Thanks!
I believe it comes together with a monopod of some kind not sure of the name
I'd I'm not mistaken, it's the foot of ifootage cobra

Hi and thanks for you great video, since it is 4 years ago, do you have best value recommendation for today?
Really awesome idea, am looking at buying this shortly. Would love to see a video on wireless low latency 4K HDMI!
I've actually just received some Bluetooth transmitters from Ali express, $4 per piece, lots of latency unfortunately!
What the transmitter and receiver does is they encode the analog signal, transmit it then decode it again, this introduce latency and require computing power. Do you expect a 400$ PC to encode a video faster than a 5000$? So 4$ transmitter is not the best choice here.
Great video, thanks :) Would love to see a similar test for wireless mic systems (eg. Rode Wireless Go, Comica BoomX-U, etc) Especially since they can also be used as a makeshift wireless headphone link!
Thank you for this video. Really helpful. Any solution for earbuds headphones?
Thank you! I will buy one of them! Was looking for this long time...
Amazing fix. August 2020 here wondering if those Avantree pucks are still the top of the line if I want to keep using my Sony headphones, or if there's something new.
Corridor Crew need to see this!
Does anyone know if there is an option out there for multiple receivers or headphones? I want this for an interview setup where the cam op and interviewer can listen to audio at the same time. Anyone know of any solutions?
Great video!! I think I like the Taotronics one best, for it's size and pretty low latency comparatively, 4 frames is not bad. I also for my own preference, don't like needing the specific headphones option nor the dual puck being it's just one more thing you have to contend with, but the latency of course is really good great review and comparison!!
Every test the Wireless Go as a transmitter?
I actually have the final option for watching TV at night and not disturbing the rest of my household. It never crossed my mind to use it got monitoring my audio at weddings. This is a great idea. Also I might add that you can increase the audio on the headphones independently of that mixer which means u get even more juice for monitoring in a noisy situation
It's not better just using an in ear wireless system?
Awesome video, you should do a test of a bunch of wireless transmitter/recievers for lav mics for a video that would be so helpful to people!
Incredible! I was searching for such comparison. Thank you very much!
Would you consider reviewing the Avantree Sky Ace for this purpose? It's a 3.5mm wireless headphone originally designed for flights.
Thanks! Brilliant! What about the Rode wireless Go hack and latency there ?
I wonder if these can be used with galaxy Bluetooth earbuds?
Great review - so after watching I decided on the TaoTronics 2-in-1 & ordered - question ; if the other end does NOT support aptX will these still work? I believe YES - just found out from the Apple Community board that iphones (and apple in general ) do NOT support aptX because they have to pay high licensing fees to Qualcomm - and Apple, despite being rich, never wants to share in paying anyone royalties - so in several hours I will see if I can use these TaoTronics 2-in-1 with a bluetooth lapel mic, transmitting to this received connected to my Canon XF-400 video camera - I usually shoot on-location with VERY loud noise background so want to capture my commentary audio ;)
So u use a regular mic to record but u use a wireless to monitor audio. but can u connect earbuds ?
This is so exciting! Here's a stupid question but could you use a headphone splitter output from the camera to multiple bluetooth devices to theoretically have a producer and cam operator both listening on their own headphones?
Dont get me wrong,wireless is the inevitable future and its damn nice not having to deal with cables tangling but my issue with having wireless stuff is its theres extra things to charge,and if you forget to charge them you cant use them. Wired headphones work all the time unless if its damaged. Theres always a give and take with everything i guess.
Personally id go with wireless stuff because im so tired with cables dangling and getting stuck on things but its just extra stuff to charge.
Could you use a rode wireless go in reverse to do that?
