Here's a few suggestions I have:
Koss PortaPro: Don't mind the nerdy looks and want some nerd cred? These look ridiculous but the sound is incredible, they're very comfortable, super durable, extremely portable and GREAT for exercising/on the go. Koss has a lifetime warranty.
Sennheiser HD428: These are really quite better than the 202/203 because these are over the ear, built very well, decently portable, have nice bass response and are fairly "fun". But they aren't too efficient. If you like loud music, I'd say stay away. But these are still GREAT.
Grado SR60i: Good, but not portable, unless you like hearing what's around you walking on campus like I do. Long cord also isn't nice for portable use, but these are more portable than people like think.
