Bose A20 Aviation Headest Issue
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!
