I have a few issues with this offer:

1. The main place I'd want to use noise-cancelling heaphones is during long flights, when I want to hear the movies they'll be showing on the flights. I am unsure if it is possible to "connect" wireless headphones so that you can hear it. I currently have wired Sennheiser noise-cancelling headphones which come with an adapter that fits those funky airplane two-pin headphone connectors, so I can use them instead of the white small headphones that they offer on flights.

2. Generally, I don't like wireless headphones. At least the ones I have currently seem to cause problems with the wireless mouse. If I used both at the same time (e.g. when playing Team Fortress 2 online), my mouse would act up so I figured the wireless headphones were interfering with its signal.

Hence, I use USB headphones when playing games. Maybe wireless headphones are ok for listening to music from your phone wireless etc., but I never do that myself.

3. Also, I hate how more and more devices (headphones, shavers, drills and other tools, even vacuum cleaners!) are going battery-powered nowadays. While it does increase their mobility without a cord, it also means they WILL break down when the battery eventually dies in one or two years, and you have to buy a new one.
