Would a ferrite bead clamp help with this problem?
I've seen reports and experienced when using Tritton Trigger headphones with wired Xbox 360 controllers, sound noise occurs, but with wireless controllers, they work just fine. Could it be an EMI issue with the extra power from USB? If that's the case, could it be solved with a ferrite bead clamp on the mic cable near the controller. en.wikipedia.org/wiki/Ferrite_bead
