Noice via USB

[TheBigSock]

I have a Tritton 720+ Gaming headset which i have connected to the back of my computer via both USB and stereo/mic-jacks (it requires all of the conectors to work.) My problem is that i get a lot of noice in my headphones when the lighting on my corsair k70 rgb is on, and/or when i am using my mouse + sometimes when i change settings in "nVidia control panel." My motherboard is a asrock h97 Fatal1ty Killer "Gaming"-motherboard. I tried to unplug the usb on my headset and all of the noice disapeared. Why is this? Do I have to get a new headset or a dedicated soundcard to get rid of the problem?

PS: the noice is both low-pitched buzzing and high pitched "beeping"

I think it is that the other usb ports have a lot of interference and screw up your headset. I would just buy an external usb hub.
