The other 2 with 3 buttons - sound works.
volume buttons don't work and I don't care for that.
problem is, the mic doesn't work.
I did a lot of testing, I found that if I disconnect and reconnect it 2-3 times during a call (and only during a call) the mic will work for about 20 seconds and stop working.
During these 20 seconds I can end the call and start a new one, use voice control, or continue my current call. shaking the cable doesn't make it stop working. It will work for 20 seconds and stop for no reason.
Seems to me like a software issue, but I am not sure.
Anyone here knows if one of the converters/adaptors would make it work?
I mean FiiO (LU1 or LU2), or ADPTR-TRRS-35 (google it, sorry cannot post links).
Since the 920 suppose to support both configurations of TRRS (AHJ and OMTP) I assumed it would support these headsets.
My non-working headsets:
1. yurbuds inspire pro
2. Audio-Technica ATH-CP500i
If you know of any other adaptor that might work please let me know.
