Let's get down to it - this is simply a great product. It's alot sturdier than the more popular, similarly priced 'Fatal1ty' headset (these were to replace them), and is slightly more comfortable. It grips your head so it is sturdy, whilst still being comfortable.
I don't have a good sound card, mind, but the sound quality is still really good. My only complaint is that with my sound card there is a really faint hiss in the background - probably because my card is terrible.
The microphone gives quite good quality sound, but not professional recording quality (what do you expect?) - still good enough for gaming though.
The bass on these headphones is quite good - the shots in games (like CoD4, CS:S) sound really realistic.
Oh, and, they're really well built.
