I have a Sennhieser HMEC 400 headset. I wasn't able to fly for a few months so stored the headset in my house. Never had any problems with it.
Last week went flying with the headset and the Left earcup is dead. Sennheiser of course has exited the aviation headset business and is NO help. We have confirmed the problem is the headset and not the airplane.
Does anyone have a schematic for the HMEC400?
We suspect the problem is related to the printed circuit board by have no information about it.
Any suggestions?
Thanks
