would this happen to be the hyper x cloud? if yes i thought they fixed this issue, guess not.
-you could however try using a powered usb hub (one that plugs into the wall) to eliminate ground loop noise or you could try a usb ground loop isolator.
are you using a laptop? (is that why you only have one headphone jack alone)?
-on laptops with mic+headphone support in one jack they are generally 4 pole (4 parts to the 3.5mm plug). you can adapt to 2x 3pole jacks from this using a simple adapter cable. you could also get an external soundcard. keep in mind if its a ground loop problem internal to your pc, you could still have issues with a usb soundcard
if its not a laptop, they make internal soundcards.
