KZ AZ09 IEM Bluetooth 5.4 Adapter, KZ ZS10 PRO Upgraded Wireless Adapter in Ear Monitors IEM Cable QDC-Pins for ZSN PRO-X/ZS12 PRO X/ZS10 PRO-X/EDX PRO/ZAR/ZAS/ZS10 PRO-2/DQS/CCA CRA (C Pins, Black)

Works very well. I love this so much that when I lost my first pair to a car accident I had to get another right away. Fits over my ear very well and stays no matter what I do or how my head turns . It’s very comfortable I barely feel it around my ear. The charging case is very convenient. The price is very reasonable as well.

This is an amazing companion for any compatible IEM. The only issue is not know knowing what performance mode it’s in (normal, spatial, or gaming) all it does it beep.

I am using the Bluetooth adapter with the KZ ZS10 Pro, and I must admit that the sound quality is very true to the original. There is no noticeable loss of detail or bass. It has been a great alternative to get rid of the annoying cables, especially when they get tangled. There are a few points for improvement. For example, I notice a slight latency, especially when gaming. It would be beneficial to have software to adjust the synchronization. However, this latency is not significant enough to prevent gameplay and does not occur all the time. I suppose it happens occasionally because I have other devices connected via Bluetooth, which may create interference. Lastly, and this is a personal opinion, the connection method is somewhat cumbersome as you have to align two small connectors, which feels almost like threading a needle. It would be nice to have a simpler method. Again, this is not a major issue but something I would like to see improved in a future update of the product.

great charger pack make sure you get the correct earpods mine where not compatiable no worries needed the upgrade

From the first time I heard the disembodied “Connected” I knew I had a fine piece of pure chinesium hanging from my ear. Not the first time I’ve used cheap products and I’m sure it won’t be the last time either. Chinese made products typically get the job done well enough for my liking, but not this time. One of the first thoughts I hadd when I first recived these adaptors was how massive the case was. Understandibly it has to fit any variety of IEM, but there’s no way I’m confortably fitting a case the size of an apple (fruit) in my pocket. Within the first few hours of using these I found I would have connection issues. They’d be fully connected, but I’d hear nothing. Putting them back in their case to reset for a few seconds would put them right though. This has gotten much worse over the past couple months. It happens several times a day and a hard reset often won’t do the trick. Only forgetting the device and repairing them will fix it. What a hastle. Most battery operated devices have some sort of internal power management system in place to warn a user when the battery level is low and shut down when there isn’t enough juice to function. These have no such thing. When the battery is low it will just sputter on and off constantly losing connection or audio until the climax of it’s slow drawn out death. Trying the whole time to function like nothing is out of the ordinary. Overall the sound is just fine, but other than that they barely operate as intended. Unless you really enjoy the struggles modern electronic devices at a constant interval best to steer clear of these.

Connection on these aren’t great. The battery only last about 4 hours when playing and anytime I start my pc up I have to disconnect them and re connect them. They are the only Bluetooth adapter I could find for the AZ09 though.

Good

Worth it to occasionally use my IEMs wirelessly. Price is reasonable. But the audio quality does suffer. It’s just bluetooth, highs,mids,lows all just meh. It is what it is. Tried to use the mic for a few calls and nothing. They either just did not work at all or people said they hard me like i was far away. I actually think it was just the mic on my iPhone that was picking up sound. Tried with the voice memo app and covered the iPhone mic and nothing was recorded. Quality is fine for the price. Keeping them as when i use my phone, having the headphones wired i had the cable caught a few times and my phone flew :). Even with all that still recommend this. Knocked 2 stars since it has a mic but doesn’t work. Better if they drop the mic at all so we can’t complain?
