How much money do you want to spend? For under 100$ I would look into some of the sony headphones, they should have them at circuit city. I've heard the 50$ and 80$ pairs and they both sound good and have good bass response, my only complaint with them is that they are not full ear.
my sennheiser hd570's kick serious ***, are light weight, great bass response, and are very clear - but if your source material (ie digital music or whatnot) is not good quality, you WILL hear it.
also, look into a headphone amplifier. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
