I have the same problem with the Bose ProFlight Series 1 headset. I sent it to them under warranty and explained the problems I experienced, such as when I move the mic, I hear banging continuously, the noise cuts out, sometimes I can't even hear any sound in the headset, etc...
I have spoken to several people who have this headset, and all have complained about the same thing. Bose "fixed" my headset; however, after 2 weeks, it started doing it again. This was last July 2023. Now, my warranty has expired, and I have no idea how to proceed with this as they will never admit that they have a manufacturing defect.
