The following is from a customer who wishes to remain anonymous:


“If I remove the USB from my Focusrite from my desktop and plug it into my phone via a USB C adapter, the buzz is gone”

System outline:

  • Computer Monitor
  • Desktop
  • Focusrite 2i2 (which has two TRS to XLR cables attached to my KRKs)

  • KRK Rokit 4 x2

“I just tried it about half an hour ago after I finished work for the day and it works great. When I plug in a micro USB cable and get power from the wall, it’s gone completely.”
