Pretty sure there are no drivers of any kind for that. Sennheiser certainly doesn't offer any, so it stands to reason that none exist.
Ehm a kind of weird. Because when i want to use the mic it wont work to even press a letter or no sound comes out of the mic. I think its because of the drivers.. So should i send the headsett in again and get a new one? Or is it the pc's fault??
