I have a scratching and whistling noise on the left earpiece from time to time, regardless of whether ANC is activated or not. Does anyone else have this? I don't think that's normal or. I don't mean the background noise either, I know that this is normal. Maybe someone has had similar experiences? Possibly a warranty case?
