so, troubleshooting my headset, I run across an article on intel about usb 3.0 devices causing interference with 2.4 ghz wireless devices, meaning pretty much all of them. the usb 3.0 Spread Spectrum Clocking apparently creates a shitload of RF noise (up to 20db), especially in the 2.4-2.5 ghz range that pretty much everything from wireless mice to cordless landline phones use. how much of a problem it creates depends on the sensitivity of the wireless receiver.
personally, my headset range went from 20+ ft to less than 2 ft.
apparently, shielding the entire usb3 device, along with the connectors, can help mitigate problems with interference. guess it's time to break out the tin foil.

yea they were talking about this on the pcper podcast a few months ago. I'm not sure why it causes the problem but the simplest solution they found was to adda usb extension and move the reciever to the otherside of the desk.
yeah, my headset receiver has a really long cord already, but still didn't help much. I ended up wrapping my hard drive and hub in tin foil, it helps alot
I don't know much about most of this, but I can tell you that 2.4Ghz is probably the most popular frequency out there. Bluetooth, WiFi, Wireless mice, Wireless keyboards are all some of the examples that uses the 2.4Ghz spectrum. The chances that interference occures may be pretty likely. But that drastically, I'm not too sure.
if you were far enough away to utilize 5ghz then the 2.4 interference wouldn't be a problem to begin with. 5ghz is for long distance(other side of the house/across the street), 2.4ghz is for short distance(same room/proximity/nearby).
Not sure if my post will help but, I do work with RF, upwards of 20 ghz, even over that. I would reccommend finding commercial shielding, you can find it for cheap, it's kind of like a mesh, like for coaxial cable. BNC connectors / cables use it. I also would reccommend maybe isolating your headset's bandwith. You can even build an RF sniffer with an arduino board if you're into fun stuff like that. That's just a side note though. If you want to get into the dirty-gerty, you can make your own usb3 and sleeve it, and individually wrap coax shielding around each wire, then finally around the bundle. IT shouldn't be too thick of a mess. There literally isn't any other way, unless you want to use an isolator, but then that just get's too large and bulky. You can maybe build a little noise cancelling circuit, but it might not be precise enough, or might cancel itself out, and you'll have a useless cable.
