I think I'm the only person with this problem. It may be my PC causing this too. What I'm gonna do is not use the USB function on the X7 for awhile. See if the problem arises again. In the meantime I'll just use the Senn GSX1000 for PC use. Well... after the Mobius review is refreshed and done. I won't get a real chance to write until Monday. Audeze caught me at a bad time, as I don't get a day off until my vacation starts on the 26th, and then I'M ON VACATION. Ugh. I'm gonna have to find time.
