Senn pcx450, beyer dt880 (250 ohm), some phaeton earbuds that Grover suggested a few years back that are pretty nice sounding for under $100. All sound great with the phone. I have a pair of 600ohm beyer dt880 phones that i have not tried yet.
I see they are all regular headphones, and dont have experience with any of them. If you get a chance, try some in-ear phones, they are a different class IMO. Only problem with them is, they fit tight in the ear and can get uncomfortable over prolonged uses.
