A must have

I use these daily with my KZ ZSX and have to say that this set simply blows any other TWS set in the same price range out of the water.
The best thing about their ergonomics is that thanks to the ear hook there's no need for me to constantly adjust the IEMs within my ears every 5 minutes, even when running.
I would have loved for them to also have some kind of volume control, but having physical buttons instead of the so popular touch sensitive nonsense is already a big plus (and I can always set the music volume from my pocket through my smartphone's physical buttons, so..).
All things considered, if you have and love your pair of KZ ZSX or ZSN (I have those too) this is the best accessory to carry and use them on a daily basis.
Granted, the sound quality suffers a little, but it's a Bluetooth module, what else is there to expect

Too good to be true.

I had high hopes for these considering they claim to use Bluetooth 2.1 and have relatively good battery life but for me that's where the positives end and the problems begin.
Packaging and product quality: The charging case and device itself seem well built and solid on the surface. They fit nicely on my ears without pinching and hold even with a lot of motion. If you're looking for something that fits easily into your pocket you may want to look elsewhere but given that these are adapters for larger in ear monitors and not just wireless ear buds then it's a nice case that will fit well into any bag / backpack.
Battery Life: These will charge several times from the case before you need to break out the USB cable and they last a respectable 6hr+ though I haven't needed them longer than that in a single session so far.
Interface: There is a single button on each ear. If I turn one on, connect it, THEN turn on the other it will usually connect and sync to the other just fine. If I only want to use one at a time that works well too. It's very clear that the woman who voiced the audio prompts did not know English though it was mostly understandable and all audio comes through at max volume which has to be adjusted using your phone or PC.
Audio Quality: I have been using these with my KZ ZS10 Pro in ear monitors. Wired my KZ ZS10 Pros are clear with punchy bass that isn't as intense as a set of rap / hip hop tuned headphones with clear highs and quieter though still clear mids. When I plug them into the KZ AZ09 BT adapters I notice a couple things. The noise floor is pretty bad during quiet parts of music or podcasts. There's a small electronic hiss that doesn't bother me when something is playing but that does get to me if I'm listening to quieter parts of a classical music piece.
Pitch Shifting / Warping: This part should get its own section. When I first connect these the sound speed / pitch shifts noticeably. When listening to a couple very familiar songs you can hear the happy up beat guitar warp to almost a minor note and then pop for a second and come back just fine. This happens several times and is more frequent just after you've connected. I handed them to my boyfriend and he noticed it on the sample songs I showed off that he'd never even listened to before.
Range / Connection: The range is not great. Now I have never tested any other true wireless Bluetooth ear buds but it is shorter than the range on any other Bluetooth device I own but even so it seems perfectly acceptable. I can listen to my PC in the living room while one room away in the Kitchen which is fine with me. The real problem is the stuttering and cut outs. It doesn't matter where I stand in relation to the source these will occasionally just decided they don't like being connected and pop in / out frequently. Sometimes it's perfectly fine and I have no issue but other days it just refuses to remain steady.
Conclusion: If you're not doing any accurate listening through these and just want easy wireless connection to your phone then it's fine I guess for the price. That said one day when the sound was warping and it kept cutting in and out I just got frustrated and plugged my IEMs back into the regular aux jack cable and never looked back. I would shop around for something else if possible or grab something like a Fiio BTR3K instead. You'll pay more but it will be SO much more reliable.
