Astro mixamp grounding issue

[LtRoyalShrimp]

Hi guys,

 

Let me explain whats going on: 

 

I use a astro mixamp to route all my console audio(Xbox 360, Xbone, PS4, Ps3) via optical to my headphones via a mixer, and I have it plugged into my PC via usb to use as my primary PC headphones as well. 

 

My issue: I hear a very audible humming from the mixamp. 

 

I have found a solution: Power the mixamp via a apple 2-prong USB charger. 

 

Since that works, its leading me to believe that there is a grounding issue either from my PC's PSU, or something else to do with the USB ports. 

 

Any help or tips are greatly appreciated. If you need me to clarify further, I would be happy too. 

 

Thanks,

try a different usb cable, the one astro includes is very low quality.

Like Skullbringer pointed out, it's probably the stuff Astro includes that's the issue. Nothing they sell are very high-quality by any means.

OK, ill give that a go and report back! 

 

EDIT: The cable astro includes is like 10 feet long, that probably does not help.
