When I travel, I take my 280s with me. They fit nicely into the pouch on my laptop bag, and the isolation is great when sitting in a window seat on an airplane. They'll fall apart if abused though, so be careful with them.

I use closed cans at work, one of the guys next to me has open ones. Frankly, when I'm not listening to music, I can hear his, even though it's not very loud. Very annoying. If you work in a cubicle type area, go with closed over open.

Way to be trolled guys. Back on topic, even though all I bring to work is a pair of Senn HD280s, I definitely got a LOT of looks from coworkers. They sit and listen with their walkman headphones from the early 90s, and wonder why I would spend $70 on a pair of cans. At work I have a Revo7.1...
