Randomgamer101Yeah i'm going to have to disagree with this guy. The HX2s are pretty great as far as sound quality goes, I can't vouch for this specific pair as I don't own them, but I can't imagine them being a massive step up in quality. Really the only reason to get these in your case is if you really case about aesthetics or are looking for a pair of headphones better suited to listening to music as opposed to games (which might not even be the case)
Randomgamer101Gotta agree with Oxybro here, hyper x is just a Takstar Pro 80 which is a very highly regarded headphone for its price. There's not gonna be much difference between it and the M220. Having said that a modmic will sound much better than the built in one on your headset
