Works great 👍🏻
I bought 2 of the kz az09 adapters, one for my castor pro’s and one for my zs10 pro’s. At $30.00 these bt adapters are perfect in my opinion. PROS: very good battery life, I use it regularly and charge the case once a week. Sound is really not much different than using a dac. Pretty low noise on these. The sound quality is AWESOME in my opinion. Good distance, probably about 30ft I’d say. Build quality is pretty solid. No issues as of yet. CONS: the only one I can think of is the case is a bit on the large size, and that’s it. Can’t really take away a star for that very minimal issue. 🤷🏼 All in all I highly recommend the the az09 adapters, they do what they are supposed to do, and do it well.

Sound great, long lasting battery (Used 8 hours+)
Gotta have your own headphones! These work wonderful, if your on one device they have no issue connecting. I have issues with multiple devices. As I am switching between three throughout the day. But the sound quality is very clear. The different ear tips make it comfortable as you want.

Noticeable lag
It works, sound quality is awesome. Only 3 stars because of the awful lag. When watching videos, the audio is out of sync with the video.

sounds cut in and out constanly
They Link to bluetooth vary good. The sounds cut in and out constanly. Same result with with 2 different sets. If they can fix that, this would be a quality set.

Great value to make use of existing IEMs
For some ~10 year old Alclair IEMs, these were cheaper than a standard cable. As I'm not touring anymore, I just wanted to put the IEMs back to use as headphones... To make them work, I had to shave down the plug area as the B-Pin style didn't fit in the jack recess on the Alcairs, but after that modification, they work fine and are snug. Sound quality streaming audio from an iPhone is just fine. It's not perfect, but for the price point, I'm completely satisfied. The case was a bit of a bonus for me when I saw the IEMs should fit in it as well, unfortunately these custom molded IEMs don't both fit while still connected to these adapters, so I need to pull one and just left the IEM sitting in the case. Not the end of the world, but not ideal.

Totally sold.
Absolutely awesome. No problem connecting, the design looks good and fits over the ears very well, sound quality of excellent. I think the "connected" voice is funny but it happens before you can even get them to your ear so you really have to TRY in order to hear it. Make sure you get the right model to fit your specific buds. I don't plan to go back to other headphones any time soon. Highly recommended.

Unstable connection
I’m Returning it! I was really excited to use this Bluetooth adapter, but unfortunately it did not work properly with my earphones. I tested it with my KZ ZS10 Pro X and KZ ZS12 Pro X, and the connection was very unstable. The audio kept cutting out and glitching, which made it frustrating to use. On top of that, the microphone did not work at all, so I couldn’t make calls or use voice features. The idea of this product is great, and the design looks good, but the performance did not meet my expectations. Because of the constant connection issues, I cannot recommend it, especially if you use KZ earphones like mine. I hope the manufacturer improves the compatibility and stability in future versions.

Super light with great fit and sound
Pros: super light, great fit, good sound quality, easy pairing, good value Cons: none so far, will update if any develop These are super light and they hug nice and tight, but that means they're functionally invisible to the user which is good. I bought them for the gym and paired them with a set of ZSTs (cheapest KZs I already had). Cost is just right for latest gen bluetooth imo. They drive the ZSTs perfectly well.

Not recommended
The sound quality is poor, plus I received it with no charging cable.
