I just did a 10 hour flight from Tokyo to Sydney and I wore my Bose QC2 buds for the whole flight. I watched some pre downloaded YouTube videos, and then fell asleep for about 6 hours of actually restful sleep. I cannot express how amazing the noise cancellation is on those things. I was in a 787, seat 29A, window seat, just behind the wing and I could barely hear the sound of the plane. I'm never flying without them again.
