Buzzing noise coming from keyboard

[ryanmj]

Good afternoon all, my new Razer Tarantula and Razer Lachesis came a few days ago, as you know the Tarantula has a headphone and microphone jack. I plugged my headphones into the slot and I can hear a buzzing noise, however if I take my mouse of the mouse mat this noise goes. Is it the same for yours? Or do I have a faulty keyboard?

It's probably interference from the mouse. Try seperating them a little or try plugging the mouse into the computer rather then the keyboard.
