Philips Sonicare DiamondClean HX9332/04 Questions & Answers

Hi Michael – actually, I was not aware they were two head sizes. I have only just discovered this now having looked at the Philips website. It seems I was supplied with standard brushes. The salespeople did not make me were of different sizes being available. However, to get back to your question. I have not encountered any difficulties at all, particularly with sound in using the brushes that I've got. Thus, I cannot really make an observation based on your description. I had an oral B, in fact several of them, over the years. There is definitely a difference in sound between my old Oral B and the new DiamondClean. However that is no surprise as the DiamondClean cleans at a much higher head speed then does the Oral B and therefore I was fully expecting it to be somewhat more noisy. However, I don't really notice a lot of difference in the noise, such that it is distracting to me. Insofar as I'm unable to offer you any satisfactory observation on my own experience, apart from saying I am completely happy with the product, I suggest you would be best served by speaking directly to Philips customer service and asking their advice. The toothbrush is obviously just you and therefore captured by the warranty, should a claim be required. I even believe they have a 30 day refund if you are not satisfied with the product. Sorry to not have been of more assistance, but I do think you are best off speaking directly to Phillips.
