I have a pair of Grado SR225s that are fantastic, but they're only good when I'm at my desk. For travelling I used to have a pair of Bose QC2s that I got as a gift. Due to the terrible head strap design they broke after 2 years of moderate use. I now have a pair of Audio Technica ANC7Bs that are exactly the same as the Bose, and have a better strap, that I picked up for $140, and they're down to $120 now on Amazon. Apparently the first version of the headphones was so similar to the Bose QCs that they got sued and had to change them slightly.
