Looking for headset

Hello, as title says I'm looking for headset. The money I'm ready to give are around 200€ (can be less). I already checked few reviews of Steelseries siberia elite and I'm getting kind of confused. They are saying that volume is kind of low and they are too expensive (also have low quality mic). I also checked Roccat Kave XTD 5.1 Digital and I'm not kind of interested in these.

Anyway, I'm interested in headset which has big bass and good quality (7.1 etc.), basically something I can listen on some music like dubstep and sh*t myself from the bass. Also, can be used for gaming (CS:GO, Battlefield, etc.)

Keep in mind that not every headset in the world is available in my country (Bulgaria) so even if I like the headset you offer, I might not be able to get it.
