I have been searching for a quality headset/headphones for quite a while now and simply cannot decide on which to chose. I would use them for gaming, but I do not necessarily require it to be a gaming headset. I'll be purchasing a mic separately so that does not matter either. What I am looking for in them is surround sound (7.1 virtual or real?). Some headphones I have been looking at are the ATH-AD700, ATH-M50, and PC 360. I have a budget of more of less $250. Any help or advice would be greatly appreciated and thank you in advance.
