I recently ordered a headset from plantronics, it's a rig 500hx and I bought the adapter it recommended. I received it today and the audio sounds completely trash, keep in mind this entire headset + adapter cost me 110 dollars or around that. The bass is extremely low and the quality of sounds I receive are worst then my older headset. I've tried and used multiple audio modifiers but I'm not too sure on how to use them, (equalizer.apo, peace gui etc) If you can help at all that'd be amazing, thanks ~ dave
