So I just received my headset yesterday, and everything was going well until I started to notice this high-pitched sound and popping from the left ear cup. I managed to reproduce the sound. I'm not sure if you guys can hear it over the video. My finger isn't touching the ear cup at all, by the way; I'm just hovering over that sensor or whatever the little box thing is. The popping noise and the high-pitched sound are what I'm trying to pick up. This isn't normal, right? The sound does go away after using it for a few hours. (That other loud humming in the back is my loud computer, by the way ignore that.)
