You'll find a ton of guys out there using the Bose Quiet Comfort 15 with the UFlyMike setup. Apparently they work well for noise canceling and are nice for commuting and watching stuff on the iPad without having to carry around two sets of headphones. Bose came out with a newer 25 model that the UFlyMike guys have been working on an adapter for, but that has been going on for almost two years now. Hopefully they get it done soon. A quick search in the forum search bar and you'll find a lot of guys on here who swear by them and they work well both GA and 121. Ps - I don't have them myself, holding out for their new setup.
