I'm cheap... I went with Sony noise cancelling, compact headphones (can get the model # tomorrow for you)...
I'm no audiophile.. But to my untrained ear the sound quality was just as good, and the noise cancelling capability more than met my needs..
Compact and lightweight makes them great for long international flights (these have probably travelled 300,000 miles at this point).. And a price point less than half of what the Bose I was considering at the time made them the right choice for me..
But again, I would stress.. I'm no audiophile.. I just wanted something to make 14 hour flight from the US to Dubai less painful...
