Thanks all. Gives me some options. Too bad demoing head phones in the store is pretty much impossible.

My mp3 player needs are just really for background noise, I am almost always working away or reading a book when I have them on, so I'm never really concentrating on the music or how it sounds. I'll be happy if they are more comfortable than my wretched ear buds that came with the Zen and sound at least as good or a bit better.

The advice is appreciated.
