I can honestly say that these are the best headphones I've ever used. They truly do cancel out the noise of airline travel and leave you in quiet comfort while you travel. I can't recommend these headphones enough. They are amazing. The ear cups fit comfortably around your ears; encompassing them for maximum coverage. The headphones are not heavy so your head doesn't feel weighted down at all. And when you listen to music through them, it is concert quality music that you are listening to. As with most Bose products, these are pricy, however, if you find yourself travelling quite a bit, this is an investment in your sanity!
