I've tested USB 3.0 2.4Ghz interference against Wireless Headset. I pulled out USB cables(preventing interference) from motherboard back panel. I put a wireless receiver into USB 3.0 port right after a USB Keyboard(mechanical RGB) port. Of course I can hear the noise and have unstable connection because of 2.4Ghz interference. I've covered a USB plug of a Keyboard with 8 layers of aluminum foil. Yes, it works. No more noise and unstable connection. Perfect.
