every pilot that i know who has owned a Bose has found something wrong with it, it's broken several times, had to send it back to the shop to get fixed, etc.
most of them are lured by the fancy ANR and lightweight stuff. but if it keeps on beaking, what's the use?
i've had my old DCs for 20+ years for my GA flying. i've dropped them numerous times and a tug and myself have both actually, by accident, run them over (tug on the ramp and me in the parking lot forgetting that i had placed them on my rear bumper and fogetting about them) and they've never lost a step in quality and usefulness.
in my experience, the Bose guys get fed up with constantly sending in their headsets for repair and eventually switching to something more durable.
