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

Great purchase
Amazing sound, especially for the price. Case is larger than current earbuds on the market but really I'm splitting hairs

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.
