So i had the same issue. Bought the headset and had a super tin sound to it. actually found this chat while i was trying to figure it out and the solution is so simple. For some reason corsair likes to charge you 200$ for a (high performance gaming headset) but has the audacity to copy and paste the Equalizer defaults. They were just lazy and did a bad tune on the headset out of the box. Here is the eq preset that works for the headset. still takes some getting used to.
