I'm not that knowledgeable with sound, but from the basic research I did I just ended up getting sehnheisers 560s on sale for $100. best headphones I have had. check the "RTINGS" website > headphones > tools > Graph and look at frequencies. do you want more bass or treble? In the end you can just download and mess around with equalizers as well.

My noob philosophy is getting a close to equal base sound for all the frequency levels then just using equalizer which is what the sehnheiser 560s gets pretty close too factoring in the cheapest price/deals as well.
