Manowars mic works fine(usb connection)

Hello to the forum.

Today I tested the manowar headsets (7,1 wired ) with usb connection and while the headphones work flawlessly the microphone works with distortion sound (in teamspeak) didn't understand me nobody what I say!!

If I connect with the jack connection all works fine.

Has anyone coped with this problem?

(I try to reinstall synaps etc nothing at all).

Thanks.
