I had my first experience with BOSE while flying on AA in business to Tokyo several years ago. I bought the QC2 shortly after they came out last year. A nice improvement over the old ones. I was on a flight to HNL last year in BF, and the couple sitting across from us were unpacking two new sets. I was watching them trying to figure out how to get them to work. After what seemed like 30 minutes, they put them back in their cases stowed them. After meal service, I went over and asked how they liked them. The wife (assuming) seemed upset at her husband as she said he had to buy these d*?!m things and they don't even work. I asked if I could see one to see if I could figure them out. Well, they didn't have batteries in them. Seems they didn't see the battery in the package. I placed the battery in them and showed them how they worked. They were both appreciative and thanked me again at the baggage claim area after the flight.

I would guess about 2/3 of the flyers in BF had either BOSE or another type of noise cancelling headsets.
