Headphones are not comparable to headsets. They are two totally different products, one is for listening and the other is for communicating. If you are a gamer who wishes to communicate with his teammates then it doesn't matter how great your headphones sound, they fundamentally do not meet the requirements. Get into any competitive level of gameplay and you will be hard-pressed to play without a headset. You'll need decent vocal communication, something hard to get with standalone mics.
