Hi, i have weird problem with my new headsets. When i first time plugged them into my PC i heard rustling/crackling noise at low level volumes. I need to raise my sound level so much that i can't anymore hear that rustling. It happens with USB or 3,5 mm jack and in smartphone or PC. This effect especially happens if i listen dialogues example in movies where actors are just talking with no background sounds. It also happens with stereo or not. My PC supports 7.1 sound, no matter if i put them into 3.0 or 2.0 USB also. Any suggestions?
