I recently bought a Clara HD, and after a few days started noticing noises coming from the device while reading in bed (when it's perfectly silent in the room). When I turn a page I hear a click, then some buzzing, and if I hold the device by ear I also hear some high pitched noises (coil whine). In fact, some high pitched noise is always there, but not audible when the device is held at reading distance.

Is this noise also present in other devices? Is it always there and should I not bother with ordering a new device?
