I brought CM storm Sirus
s few days ago. 5.5 k with vat is the price. It performed wonderfully as it should be, deep and strong bass, very clear and sharp treble sound.
I connect it with creative Audigy soundcard which produce wonderful realistic sound with Eax Ad HD.
But with onboard soundcard it
never be the same.
Corsair Vengeance 1500 is good headset and cheaper than Sirus. Reason for choosing Sirus over Vengence is:
Corsair Vengeance is not true 5.1 headset, it has USB soundcard(I already have one USB headset) and it is
basically stereo, use the software to emulate surround sound.
Sirus has 4+4 drivers on either side and I can control volume(of each 4 (F/R/C/ Sub) separately
with in-line volume control.Corsair Vengeance 1500 comes with single driver, remote does not have separate volume control for
5.1 surround sound, can be control only through
software.
It is my personal choice to play with true 5.1 headset and avoid virtual.

But I can say Corsair Vengeance 1500 is also a good option. USB Headset does not need good/any
soundcard.
