hello there is something wrong with ever usb headset i use there is this load buzzing sound u can hear when u stop like you tube or when your in a game and the sound stops for a cut screen i have tired sound blaster recons/turtle beach px5/ turtle beach px21. they are all buzzing ... when i wiggle the power cable that is on the USB i can hear it changing pitches.
i also have problems with my keyboard and wireless mouse when useing my desktops usb ports. my keyboard will type extra letters and my mouse will sometimes stop then jump a little

things i have tried
useing a different power strip and different out lit
used all 3 headphones on my laptop and they didnt have this high pitch sound and also tested the keybroad and mouse and those never messed up
i tired unplugged all of my things connected to the usb and didnt make any different
iv tried all my usb ports on the desktop it has 10 usb 2.0 and2 usb 3.0

mobo is msi z97 g5

Buy a DAC/headphone AMP combo, and get some real headphones.
