It doesn't work on Samsung, Xiaomi, and Realme that I tried it on. I don't know if what I got is defective, the charging, although slow, works but the headphones don't work.

In my old phone (Xiaomi mi A2), it works fine and charges while playing music at the same time. In the new one (galaxy s22), it displays a message that the device is not supported and the headphones don't work at all (I haven't tried charging, but since the sound doesn't work, I don't care if it charges through the adapter).

The problem with these adapters is that they do not have good construction. When I plug in the headphones, the charging stops and vice versa. At the same time, I never have them. So it doesn't do what it's supposed to. Unfortunately, I have experienced this with another one that had simultaneous 2 type-c (split).

This specific item arrived broken, the headphones were not working, I tested it on 4 different phones

Simply unacceptable... As soon as I opened it, I tried it on my phone, tested the headset and hands-free, and the sound was only coming from the right earphone, it was blurry, and furthermore, it didn't charge either when I had the headphones on or without them. I do not recommend it at all!
