I get back to my destination feeling much less worn out and don't seem to suffer as badly from jet lag when I have them on. I like the removable cable, so I can read or explore the cabin without the cable dragging behind.

There's a us Airways promo on at the moment.If you shop at 5 stores, you can get 3,750 miles for buying these headphones http://www.usairways.com/en-US/dividendmiles/promo...

Just wondering what people think of these and if they have experience with QC3's. I have a pair of QC3's and recently discovered that any Bose store will let you trade in your old QC3's for the QC15's for $100. Mine are pretty banged up at this point. Just wondering if the upgrade would be worth it.
