Headroom also has some recommendations on headphones for noisy environments.
When I was a traveller, I used to use sony nc-20 noise cancelling headphones. They didn't cancel as much noise as I wanted, and the fidelity was 'just ok'. They were best at cutting out low droning noises like a bus or jet engine. The metal backed sony mdr-v6's were almost as good at shutting out noise. Both headphones are reasonably small and comfortable to wear. The v6's were more rugged, the nc-20's folded up very small. Neither one of these can hold a candle to my senn 580's.
I never tried the etymotics. I was a little concerned with having a speaker THAT close to my eardrum.
