I just picked up the Bose QC15 and i love them. My dad has the QC2 and you can notice a big improvement in the noise cancellation on the QC15. They are SUPER comfortable too. You can wear these for hours and you won't even notice you have them on. Sound quality is top botch as expected with Bose. Not crazy on the bass where it will drown out everything. I hear Dre's are too bass heavy, where the Bose is very well balanced out. I think it would be a good investment for you since you travel alot. Its basically what they were designed for. When you walk into a Bose store and test them out, they emulate the environment of being inside a plane where all you hear is the engine rumbling, and once you turn on the headphones you hear how well it cuts out the noise. I got a great deal on them at the Woodburn Outlet in Oregon (tax free woohoo!). So yea... because you travel... i highly recommend the Bose
