Some nice over-the-ear headphones for an MP3 player?

I recently bought a Zune HD, and I've decided that I'd like some over-the-ear headphones for it. I'd really like them to be noise canceling, and as small as possible. They'd have to be under or around $50.

Also, It'd be awesome if the headphones cupped your ears.
