I just bought this headset and initially plugged it in via USB. The quality was bad, the mic volume kept cutting out or going super low. So I just plugged the headset into the headset jack and the mic into its mic jack instead. Now testing the mic the volume is very low. I turned the mic volume all the way up, I have to have the mic super close to my mouth and basically yell into for it to sound decent. The quality is a lot better when NOT using usb but the mic is a lot louder when in usb. Any help? I am using windows 7 btw. I just want decent mic quality and I don't want to mic to keep cutting out/going real quiet when I am speaking.
