Sonic toothbrush
Question about Philips Sonicare DiamondClean 9900 Prestige
Is your toothbrush that loud too? I personally can't switch on level 3, otherwise the neighbours will complain. My old 4300 is quieter than level 1 on the Prestige. My girlfriend's 5100 is not audible at all compared to the Prestige. Equally loud with or without the brush head
No I don't have this problem.
I think it's a defect in your toothbrush. I would send it in for service

Well, as loud as a normal electric toothbrush. So far, neither my wife, children nor cats have complained.
No, don't know the problem - is quieter than the Sonicare 9000
