Okay... So I bought the Razer Kraken 7.1 chroma and when it arrived it was all well until I plugged it in and heard this buzzing. I refunded the headset straight away after trying numerous methods thinking it was just that single headset. When the new razer kraken headset arrived the same buzzing noise persisted. I have tried turning the lights on it off, moving it to one of the back usb's, I just don't know what to do. Btw I do not have a sound card and I'm also using an extension cord to power up my pc however I tried using the plug and it was no different. Any help would be appreciated. Thanks!
