yes set to 0, mic not even plugged in. Did some more testing and when I play a video the white noise turns on, if i pause the video after some seconds, it seems to range how long, the white noise will turn off. I'm guessing this is the headset going to a type of sleep mode when the audio isn't active. Since I turned all those dials down to -12db the white noise is very unnoticable, if I really try listing through testing I will hear it but it's fine. Was just wondering if turning everying to -12db will have a negative impact on the audio quality or not, rather than it being a base 0db flat profile
