Definitely very good hearing protection, but sits too tight. My little man is only 7 months old and with him the hearing protection sits already much too tight. He immediately bitched and shall only be peace when the was down again. I had to spend a lot of strength to the ever so far to draw from each other so that it fits in his little head. Actually a pity, because the processing is really very good and it looks great too. Have these returned and ordered from another company.
