Keep in mind it doesn't have to be a pc related manufacteror, I think some of the professional audio companies make much more quality gear then people like Creative and Asus.
I've dabbled in sound editing on my pc, and I've had nice reference monitors, M-Audio interfaces/headphone amps. They are all dedicated components and work just as well if not better than those 2 boxes you listed.
hi thanks can you recommend and around a £100
or will my MB get the full sound out of my head set?
