Anyone that recommends Beats for music quality are fucking retarded. Beats are designed to be extremely bass heavy while leaving everything else out. Not neutral at all and have no sound stage, everything is muddy due to their insane bass boost. Also if this is your first foray into headphones I suggest buying something cheaper first, once you get into the higher ends of audiophile grade shit it's going to be harder to recognize differences between different headphones.
Get some ATH-M50's or some AKG's at first and then decide if you need something even better.
