As a result of these findings Maxell have produced headphones targeted specifically for children with this in mind. Maxell Kids Headphones include a special input limiter which ensures that the maximum input to the driver is lower than that of other headphones. This limiter restricts the output to a maximum of 90 decibels allowing children to safely enjoy their music with very little risk to their hearing & providing parents with reassurance that their children can listen safely.
