I HIGHLY recommend the Beyer T1 if you can swing it. Pretty pricey, but you can often find it around $600 on Head-Fi, e.g.

The T1 is my current regular headphone. It is an open design though so ambient noise is an issue. (They call it semi-open but really it doesn't sound that way, esp. compared to the fully closed Denon D5000 which I also own.)
