I have the Speedlink Medusa 5.1 Surround Headset. Bought it for about 1700 CZK, which, if you do the math, is about 70 bucks. I dont have a single gripe against it. I have never been upset with them in ANY way. I've gamed with them heavily - eg eight hours on end, and nothing made me want to remove them. The ear pits are comfortable, well-padded, and absolutely no sweat problems. The headset is just the right weight for you to be able to feel its presence on your head, but not in a distracting way. I stopped noticing it after a few moments of intense Quake III gaming though

Surround sound? Pretty decent. Reviews say its the best headset out there if you want surround sound. The subwoofer is extremely powerful considering its size, turning up the volume and bass in some hardcore techno/hardstyle song can make the entire headset shake. No kidding. Best to hold it at arms length when it does that though.
Check some reviews, but as a gamer and music listener I would definitely recommend this headset.
