The various Braun Oral Bs' we have make a very faint creaking sort of whirring noise (while turned off) after being on their induction charger. You have to hold them close to your ear to hear it (well bay boomers like me who spent too much time in night clubs listening to load music in the 70's do) but as nothing should be moving inside why does it make this noise? There is a simple coil in the base of the toothbrush that which sit over the induction charger when it is seated in it. mainly just curious although I also have a dead one that no longer makes this noise and wondered if this was a clue to the cause (I have opened the dead one up and their was just a little moisture inside but no other obvious faults).
