Just got mine today paired with zsn pro. Problem is during calls, volume are too low and barely hear the person on the other side. No problem playing music.
This could be due to your call audio and regular audio being controlled separately, you can click on the three dots when on an android phone and turn up the other volume
just got mine and use it for 2 months too, it was SO SO SOO... AMAZING with KZ ZSX. Using it during office works and workout. but im still curious does KZ ZSX and AZ09 Pro was built with a sweatproof? like sweat from morning jogging 🤔 just wonder if you had any idea about it, its gonna helpful
They are not designed for workouts...if you want sweat proof...go for the CCA BTX. CCA is the sister brand to KZ and the BTX has the SAME technical specs as the AZ09 Pro (e.g. Qualcomm QCC3040, etc)...but a snugger fitment around the ears and better sweat resistance. I prefer the KZ AZ09 Pro for long hours of comfortable wear...hardly notice them while they are on my ears. However, the CCA BTX is physically a more robust design. I suppose that if I lived in a very humid environment, I might try some lightly applied ceramic coat to the silicone rubber and plastic to repel moisture...but that would probably last for only a few months at a time (with daily use of the earhooks). I have used ceramic coat on my black Persol eye-glass frames to extend their glossy lacquer life...and it worked terrifically fine (last about 6 months per application). Even a cheap bottle of ceramic coat (the 9H stuff off of AliEx or Amazon). IMO.
Did you test some more with the iPhone? No syncing problems with YT videos? And how is the latency and sound quality using the iPhone? And how is battery life?
I don't use an iPhone as my primary phone anymore, but I would assume it's the same as on android except it uses the AAC codec instead of aptX, both codecs sound good. The battery life is extremely good, I can go over a week of daily use for a few hours with them.
I switched to Sony Linkbuds A about 3 months ago but until then I didn't really have any problems, other than whatever adhesive was used inside the ear hooks at the connector seemed to be slowly returning into an oil that was very sticky. I didn't expect that to happen, but if you're keeping the IEMs always connected then I don't think it is a big issue.
any idea how they would work with standard .78 pin recessed 2 pin connnects like on the truthear holas. The different B-Pin, C-Pin, QDC etc is really confusing for me
Did it have any interference on busy places like malls parks streets etc. I have seen one review that mentioned he experienced bt interferences on malls
I've taken a few calls with these and understand that the microphone sounds fine but picks up a lot of background noise, but it is very usable for that.
@@scellyyt 1. Connection issues, if you put them in pocket, bye bye stable connection 2. You have to turn them off to disconnect from device or to disconnect them in device bt settings 3. Microphone is crap. Try using JBL BTNC 650, on action you get them for 65e, and they are like 10 classes above this....
@@stasasekulic6917 I don't see how your first point would affect the listening experience. If I put wired IEM's into my pocket my listening experience is equally non-existent? Your second point doesn't carry much weight either as they are intended to connect to only one device at a time, right? The same goes for the microphone, though I personally never use microphones on Bluetooth audio devices. I think it looks silly to talk into the air and I like having the social indicator of having a phone to my ear when I make a call in public. Next to that, I like to hear myself properly when I speak to properly measure my volume and tone. Lastly as an alternative you suggest a pair of on-ear Bluetooth headphones that are most optimistically 2 times the price, but more typically around 3-4 times the amount. Those things are overpriced, mediocre at best and easily outclassed by others. But more importantly they are completely different products and they also have a different target audience. The KZ AZ09 Pro are specifically designed towards the 'budget audiophile' crowd, to give Bluetooth functionality to one's IEM's of choice. They come with compromises in exchange for convenience and portability, where the priority is to keep the sound quality/fidelity as high as possible to fit the budget. They go hand-in-hand with KZ's budget-friendly IEM's
I'm having a hard time with mine.. I received mine today.. When I turned on to test it, one of the sides (the right one) seems to not be working. In the case, the module turns on the led in red (but a weak red) However, when I take it of from the case, it simply doesn't turn on. I have already tried so many times and so many different takes on the button of the module.. And yet I cannot make it work. There's nothing on the manual on this subject. Can you help me with this issue?
Clean the charging contacts on the broken one and the contacts in the case where it fits, and try to press it and wiggle it about gently when you put it into the case. It should light up with a solid red meaning it's charging, and then it should work. If it doesn't, then return them to the seller or request a refund because they sold you faulty goods.
Yeah, for me it's the left one is always cutting out. I mean, sometimes it might go 20 minutes without cutting out, but then it will cut out three times in one minute. It's almost always annoying enough that you just give up.
Sound quality is faaaar more than just deep bass and treble. If you want a spotless audio experience, just use the wire. These Bluetooth adapters introduce a slightly noticeable amount of noise and mild distortion with low bass notes, which is why I use them for convenience more than sound fidelity. They do sound nice, but it's not as good sounding as just a plain old wire.
Honestly, I dont get why people are saying corded is better (though I can understand it depends on IEM). I use CCA's CRA, and have loved these sinxe I got them, and these adapters make it sound just a nudge better to me (and also remove my need to turn on an equalizer, as whatever these are doing does the job 10x better), PLUS I'm getting absolutely no buzz which is absolutely incredible compared to the wire. If I still had my KZ's I'd test these adapters with those, but I lost them a while ago.
I've since switched to some sony earbuds, but these adapters were pretty decent. For me though it was just the convenience rather than the sound quality, as I found these adapters would increase the noise floor substantially compared to using a cable plugged into my phone.
@@scellyyt 2.4ghz wifi is known to cause interference with bluetooth(also uses 2.4ghz). its not a unique thing to this adapter. u can do a speed test with bluetooth on and off and see your speed drop by 80+%.
@@hailgod1 I know, I'm just saying changing the WiFi connection on my phone would be very unlikely to change anything. And that speed test thing isn't true, I can easily get 200+ mb/s with them connected.
As I mentioned in the video the lights should turn off while they are playing audio. If not you can do what I did and covered up the lights with some label paper.

can i used it only one piece at time? mean 1 in the pod the other on my ears@@yoeladrianta6082

Hi mate. Is it still working? How is the battery? Thanks!
Probably it's swollen
Earhook too wiggle and soft. U have any way to harden it?
I'm not sure how I would do it, maybe sections of heat shrink tubing?
@@scellyyt already try that, not work plus my earhook now become more soft. 🥲

what brand of android phone do u use, and what iem you use ? may i know if you hear hisses while using the bluetooth adapter
When I used these earphones I had a Poco f2 pro, and the adapters did introduce hiss but not a large amount.
@@scellyyt Thanks!
any idea how they would work with standard .78 pin recessed 2 pin connnects like on the truthear holas. The different B-Pin, C-Pin, QDC etc is really confusing for me
The pin pitch probably just changes how well it fits, but try to get the right pin pitch anyways for the best experience
Did it have any interference on busy places like malls parks streets etc. I have seen one review that mentioned he experienced bt interferences on malls
I haven't experienced any of that yet
How is the calling experience? I'm looking for something that enables me to do calling as well, any suggestion? (Android user)
I've taken a few calls with these and understand that the microphone sounds fine but picks up a lot of background noise, but it is very usable for that.
@@scellyyt thanks for your quick response.
Any ideas on how to switch devices on the fly? Or just have to switch off bt and do manually
They can only pair to one device at a time so you'd just have to switch off bluetooth on the device they're currently connected to
