I think I can hear that noise you mean if I hold the mouse very close to the ear. It sounds like a quiet, high frequency whistle? It's pretty hard for me to pick it up because it seems I need to press the shell into my ear to be able to hear it, but when I do that I also hear scratching and whatnot on the ear while that coil whine is so quiet that I struggle to focus on it.
What's interesting is that it seems to shut up after a while of holding the mouse to the ear, after about ten seconds or so. When I put the mouse back onto the mouse pad and then pick it up again and hold it against the ear again, it's back for another bunch of seconds. This is perhaps the power save mode of the sensor that it goes into when it fails tracking for a while?
It shutting up after a while is how I noticed that it's real because that coil whine is so quiet that I could barely say if it's there or not.
