Difficult to tell, since that could be anything from you breathing too hard into the mic to there being some kind of defect in the hardware. So probably the first thing to try is repositioning the mic, see if there's any change.
i just both a dreamgear gaming head set and the sound is amazing but when i used the microphone theres a static noise. i am just wondering if its normal or if theres a possibelity to fix it...please reply . thankyou!
