Does anyone here experience "interference" while using the Bose X in the cockpit? To me, it sounds like a high pitch "eeeee" sound dependent on which way my head is facing and distance from the circuit breakers behind my head....
Sounds like you have an issue with your headset, it happens. Mine was messing up a few years back with a high pitch tone. The only way I could get the tone to stop was to touch a piece of metal. Really weird.
Call Bose and send it in for repair. They'll even replace some small wear and tear items while they have it.
