I use a set of Beyerdynamic MMX 300. My particular model is outside of your price range, but the sound quality and comfort level of Beyerdynamic can't be beat. The MMX 300 has a mic attached to it and is professional quality.
The Beyerdynamic 880 Pro is $197 on Amazon right now, down from $379 and it's a deal you're not going to beat anywhere. The 770 Pro at $158, but honestly the 880 is a better deal and a better set of headphones. Unless you're really trying to pinch pennies for some reason, I recommend spending the extra cash and going with the 880.
I guarantee you're not going to get a better set of headphones for the price anywhere. Beyerdynamic is a German family owned company and audiophiles cream their shorts at the mere mention of their name. It's super high quality audio, very dependable high quality construction, and very comfortable to wear.
There is a 990 for around $250, but I don't recommend it because it's for studio use and the earpieces have an open back. They sound nice, but are meant to not block out outside sounds. Unless that sounds like a nice feature to you I'd go with the 880.
Beyerdynamic headphones will spoil you, I don't like using other headphones anymore since I got mine because they seem cheap and don't sound as good.
