Go on ebay and find ya self a pare of sennheisers you won't be disapointed and if you want a headset they make amazing headsets too with the sound quality and a really good noise reduction mic, they are really good.
3D sound is a load of bollocks as you can go and buy yourself a pair which have about 6 connectors the sound quality will be poor and you'll just have a lot of messed up sound.
Guy at a lan party had a pair and he was screwing one speaker stopped working
