Because I wanted a higher audio quality than most 'gaming headsets' at my budget usually offer, I've been looking into headphones that would do the job. I want circumaural, noise isolating headphones(leather earcups) that can deliver decent sound quality for around $65. I'd also like 5.1 or 7.1 surround sound, but I haven't been able to find any headphones that offer it. How big a difference does surround sound make; would audio technicas or sennheisers in this price range be adequate? Any suggestions?
