Maxwell using AUX source itself (BUG)

Hi guys, let me explain. Out of nowhere my Maxwell decided to only use AUX source, and since it's unusable because I can't choose the audio source, headset's not connecting to the dongle, not working on wired, the only thing it does is saying "AUX... AUX... AUX..." again and again. Didn't plugged anything in the AUX port, actually I can do nothing at all to make it work normaly. I tried factory reset, firmware update, everything I could do but nothing's working. Is anyone has the same problem and a solution ? I'm living in France so sending back the headset to Audeze will take way too much time (I'm planning on moving out).

​

Plus, I don't know if it's a thing but the LED near the noise suppression button is red instead of blue.

EDIT: the AUX source is working but I can't use the mic and I want a wireless headset ...
