I have a 3-4 year-old A20 Aviation Headset that has recently come up with an issue. When noise cancelling is turned on, the left ear cup has a loud squealing/squeaking noise that occurs whenever I move my head or adjust the headset. It sounds almost like two peices of plastic or metal are grinding against each other, however, it seems to only happen whenever noise cancelling is selected on. I've tried moving the ear cup and listening for the from outside the heasdet, and it is audible. When noice cancelling is turned off, no squeaking noise is heard, both with the set on and off. Has anyone else had this problem? Any solutions? Or do I need to send it in to Bose for repair? Thanks for any input!
That sounds really unpleasant. You might need new earpads to make a better seal with your head.

I'm sending one of mine off for repairs today. The two I keep up front (6-pin w/ bluetooth) both do it when you turn your head and unfortunately the warranty had expired by the time I took ownership. I'll let you know how it works out, the Bose folks said it'll take about 3 weeks and they go ahead and refurb the headset as well.
