In my opinion true 7.1 headphones are awful for music and really everything other than determining direction and distance of sound in a game, even then i'd prefer a good open back dual driver studio headphone with good soundstage.
I'd personally rather have the hyper x cloud 2s than those revolvers. The cloud line are based on the pretty good takstar pro 80 studio headphones.
I use a pair of sennheiser HD58X's with a mod mic and am very happy with it. If you really want a pair of "gaming" headphones pretty much the only thing I could bring myself to recommend are the sennheiser game zeros which from my understanding are basically sennheiser HD558s with a coat of red gamer paint, a mic, and a bass boost.
