Bose. Not only a great piece of equipment, but a superb company too.
I had 2 pairs of the older Bose. Then they came out with the QC15, and offered a trade in of any prior Bose, in any condition at all, for $100. I accidentally ran over one of the old ones with my car, took in a bag of perhaps 100 bits, dumped them on the clerk and said "you said any condition at all".
No problem. New QC15!
