Last month by Bose Quiet Comfort Headphones broke. A little piece of plastic on the right side of the head band broke, allowing the right earpiece to flop out. I was bummed; these aren't cheap headphones.
I called Bose expecting a run around of one sort or another. Instead, I got a flat-out "send them back and we'll replace them free." No receipt proving purchase date, nothing. Just "send them back." The new ones arrived today, about a week after they received my old pair in the mail. Very impressive.
