I had the Sennheiser Game Headphones Zero brought me here, but rather the feeble sound of my ASUS NOTEBOOK G750JX, just listening to music. Since then, however, he takes this Kopfhoererverstaerker, I am absolutely satisfied, sonically the several classes are difference. I had ICN terms ASUS sound card first concerns, since I've always trusted the creative products. The good reviews here and elsewhere, the tests, however, have prompted me to take "the risk" - and - I'm thrilled. Even without software installation under WIN 8.1 very good to use and good sound quality.
