Chalk up another vote for the Sennheiser HD280 Pro headphones. They are so crystal clear, that it's almost intimidating! The closed back style cans completely cover the ear and form a tight seal that shuts out the wolrd and immerses you into the music and your mix. I do Voice-Overs and these are perfect for identifying any imperfections in your voice. Grab a pair of these today dude! $99 at most stores....
