Last year we looked at a couple of Sennheiser headsets, including the PC 330 G4ME, which we were very impressed with. Today we'll be looking at the follow up to that headset, the PC 333D G4ME. The main enhancement which the PC 333D G4ME brings to the table is the inclusion of a USB sound card featuring 7.1 sound and Dolby headphone technology. So, will the PC 333D live up to the high standards we've come to expect from Sennheiser?
