Bought a Corsair H2100, worst Corsair buy I've ever done

This. Hissing. Noise. How do I shut it up? I dont think I've ever been this much annoyed of a buy from Corsair, I will try to get a refund. However, after looking around a bit, and talking to some of my friends it is the noise cancelation that is the big thief here (apparently). The constant hissing noise apparantly IS the noise cancelation, and I wonder if anyone have figured out how to disable it yet

I have managed to disable it by "tricking" the headset I guess, simply by enable low frequency protection in the enhancements tab in playback devices (win7 64bit). This will make the hissing noise stop, but as soon as I start listening to something again the hissing noise is back up.

I am kinda hoping Corsair will patch in a feature in new drivers that lets us disable the noise cancelation feature, if possible.
