I have a pair of headphones that use USB to power them and I get alot of noise from the USB port, I had the same headphones last year but they used a DC adapter to power them and the new style now uses USB (my old pair broke)
Would a powered USB hub work to power the headset and see if that helps, or is there some sort of USB device I can get that is separate from my PC to power them.
A powered hub SHOULD work fine, unless is has some sort of logic that disables power to the downstream ports if there's no upstream connection. That seems unlikely to me...
Just to clarify, what I meant to say was the cheapest powered hub you can find. In other words, it needs to come with a power cord that plugs into the wall.
