After about ~4-5 years my G930 Headset got damaged. The mic arm broke finally.
But thanks to simonx for :

Disassembled the headset, cleaned it, replaced broken part.
Had to help a litte with the hair blower to bend the fingers in the right position. Now even the auto mute on upper position works again.
If you hear something clapping in the headset afterwards you probably lost the counter nut and need to disassembled the whole thing to reposition it. Did some bad connections ;(
