Headphones buzzing noise

[TidusPrG]

Hello guys, currently im using some Corsair Raptors HS40 and i was checking the microphone on the other day and it makes a loud buzzing/humming noise?
I tried changing some settings but no luck, one thing i noticed is that if i put my hand on the case the buzzing noise stops ??
is it ground issues with the pc? i have it on my desk atm

Yeah, sounds like a grounding problem.

I assume you are using a power cable with earth wire/pin, and that is plugging into a mains socket that is earthed?

I am not sure, i know how to check the extension to see if the earth cable is actually on..
should i remove it or leave it on?> thanks
