KZ AZ09 Bluetooth 5.4 Upgraded Cable Wireless Adapter Cable C-Pins for ZSN/ZSN PRO/ZSN PRO-X/ZS10 PRO/ZS10 PRO X/EDX PRO/AS16/AS16 PRO/PR2/ZEX PRO/AS12/AS24/DQS/C12/C10 /CRA cca

Compact, surprisingly sturdy Bluetooth gadget with solid pairing, clear audio, and decent battery life. Intuitive controls, lightweight design, and excellent value for everyday use. Highly recommended.

I was already blown away by my Linsoul KZ ZS10 PRO Earbuds, but my only gripe with them was the fact that they were wired, so I bought these to fix that one caveat. They have worked out of the box and after usimg them for a good 6 weeks now I can safely say they are brilliant. I purchased these with the expectation that the audio quality would drop by a significant amount from the KZ ZS10's stock cable; There is definitley a difference in audio quality (as wired conections will always win that fight) but the drop in audio quality is really not anywhere near as bad as I expected to be, and with the flexablity that the wireless connection gives me means that I have more freedom where I can use my headphones without the risk of accidently rippin them out of my ears or catching the cable on a door handle. It also has meant that I have started using them for gaming on my PC and and the mic has not had any complaints from my friends over discord. Pros: Quality Connectivity Battery life Freedom for use with bluetooth devices instead of just 3.5mm jacks Cons: Slight audio quality loss over cables (at least with Linsoul KZ ZS10 PRO) Overall a very worthwhile purchase. 5*

The audio is on par with other AAC Bluetooth headphones, yet doesn't compromise in any single department. It does excellent in latency, getting around 200ms on its 'high performance' mode. The fit is generally good, however it can irritate your ear if worn too quickly without adjustment. Also the case is large so you can fit large IEMs into it. It charges via USB-C and has an extremely long battery life on both the case and even each IEM (you'll be able to play for about 10 hours roughly without having to take them off your ear) and charging is fast (on the IEM stems). However, the one thing that has ruined it for me is the fact that the device would turn on while in the case and pair and just stay connected to my phone or whatever device was connected to. This is quite a big deal, because it happens randomly, even if I put the case down on a surface gently it will after 3-4 minutes turn back on and reconnect. I would miss calls notifications and would often go insane. Luckily for me I can just turn off Bluetooth on my devices, but I don't enjoy doing that because the convenience of just opening the case and having a connection is really nice.

used for gaming an music this perfect for me , KZ Castor ,KZ ZS10 Pro , KZ EDX PRO, all work great .as there so cheap i have three pair great for Audiobooks for a long travel .

These have been great—long-lasting battery life and incredibly lightweight. I hardly notice I’m wearing them.

Changes a pair of wired kz into blue tooth in ear monitors! Absolutely amazing, great battery life, same great sound, but without the cables in the way, a bonus when you’re working. Only regret is I didn’t buy them years ago!

Sweat corrodes the charging connector and the headphones will stop functioning. Can not wear these during exercise

You won’t beat these. Great price great range, long battery life. Reasonable sound

Écouteur parfait 👌 Ils tiennent bien la charge, avec un son de qualité et ne sont pas du tout fragiles la boîte de transport et un poil plus épaisse que les écouteurs classiques mais ça vaut largement le coup pour le son qu'ils fournissent ! Je recommande 👌

Work perfectly for my Blessing2, used them for a full 8hr shift and didn't die. Met all my expectations on quality, battery life, and ease of use. I definitely recommend these adapters for other 2-pin iems.

compared with Linsoul TRN BT30 Pro. Its not that great but wurks good

Tragekomfort sehr gut

Es un cubito negro con los adaptadores. Se siente de buena calidad y firme. Para lo que lo he usado, que es escuchar música y vídeos, funciona bien por el momento. Sin ningún problema. Viene con un manual y un cable para cargarlos.
