My own problem is that I don't have any idea it needs a dedicated sound card for 7.1 surround sound. After I bought one, I have a problem of turning the microphone on. After I sell it to one of forumer here, he doesn't complaint. So maybe the fault is at me not knowing the setting whatsoever. Buzzing and hissing problem should be able to solve by changing the usb connector to another usb port. Rather than that, I think the surround sound did great and maybe it would have been better if I know more about sound and setting it to my own preferences. The stretch pad also works nicely to fit any size of head. Weight? Okay for me.
