Looks like a very polished (no pun intended) device but I never understood why some people bothered about other people hearing them while on the loo. Natural noises like blowing your nose, sneezing or even farting! I know what in Japan for example it's an issue and people continuously flushing the toilets so other people can't hear them. Maybe it's cultural.
