I brought a pair of Sennheiser PXC-450s - they are nice in that you can turn off the noise cancellation and use them without batteries (and get a boost to the sound quality by doing so), but if you are on a plane or just have loud neighbors in the office I can turn it on and cut down on the outside noise. The cancellation itself isn't quite as good as the QuietComfort ones but it's close enough.
