Arcrtis 3 didn't come with registration code and this headset no longer is supported on SteelSerie's Engine for their gear. I setup the headset with the twoplug-ins in the back and it seemed low, so I changed to one plug-in the front and it still seemed low. I then changed it back to two plug-in and put it in the front and it still is low. I even enabled loudness equalization and it still is low. Is this headset just low or is my pc lowering a setting?
