for your info corsair have a significant issues with their products and denies this fact but, some Corsair Vengance 1500 v2 idk about v1 but v2 produces for someone a constant hissing sound, you could tweak around this in windows 7 and 8 +8.1 but with windows 10 you might have issues
its due to their software that the headset uses i bet
currently working to fix this issue, with no luck so far :/
