I was using a Phillips O'Neil streak headset Before they broke 3 months ago and the sound quality was pretty good, the con was that the headset bass was a bit weak. So explosions for a fps didn't have that pop and would sound a bit muffled and lost in the background. I don't know how the O'Neil headset compares to the beats headset but they were lightweight compared to alot of the high end gaming headsets. Especially lighter than the gaming headset I have now (afterglow prismatic wireless).
beats are generally heavy on the bass, thats there thing, i have yet to find a headset that has better bass reproduction then beats there problem is in the HIghs sometimes they can come off a little Tin(y)
