Go over the Headroom, like someone else suggested, and they have a little review on them plus several graphs. I recommend highly recommend Headroom.
Link For the lazy people, they say "A little bright sounding, but good for light acoustic, voice, and classical music. If you're listening to rock and pop, you should consider the Koss UR20 and UR30 in this price range.
Though not as pretty as some headphones, these cans are comfortable, have a self-adjusting headband and single-sided cable attachment, and are driven fairly well by a portable CD player."
