It's USB, so I'm not even sure if it's using your sound card for audio processing or not. Not clue how USB audio devices work.
The USB headsets all have an internal sound card built into the USB device. It bypasses all sound from your sound card and just uses its own source. Its definitely not the ideal way if you have a good sound card, but it suffices for most onboard solutions.
For the problem you have, I say to disable the wireless internet card and see what that does. I've heard of many problems with wireless internet adapters interfering with other components, usually headsets, so remove that and see if your problem persist. If it goes away with the removal of the wireless card, maybe see if there is a way to adjust the frequency of the headset and wireless card so they are operating on different wavelengths. If not well, time to go back to a wired headset.
