My primary flight instructor ran over his old DC's with his car (I saw
it happen, and there didn't appear to be a single salvagable part on the
headset). When buying a replacment, he mentioned what had happened and
the clerk suggested he call DC and tell them what had happened. He
did,and they told him to send them the headset. They sent him a
replacment free of charge within a week. It isn't like the one he ran
over was a new headset either, they were about 8 years old. Somehow, I
don't see Bose doing that.
