We have this hearing protection for our three year old daughter bought, which is somewhat sensitive to noise and, for example, children do not like to cry. The product has fully met our expectations. The noise reduction moves in a pleasant area, you are not completely deaf despite hearing protectors. He of course is also good for parents, thanks to sliding brackets. Comfort is ok, it is also quite robust and has survived unscathed so some fall to the ground. Good Buy!
