Quies Ear Protection Special Plane Children 1 Pair are ear protections essential to sensitive ears for every travel in plane, train or in altitude. They are intended to children from 30 months. Developed for children suffering of earaches during pressure changes in plane, these ear plugs allow to pass a comfortable travel. Thanks to their ceramic filter, they regulate the passage of air in the ear during a pressure change (during take-off and landing in an airplane, or when going through a tunnel). The eardrum then adapts gradually to the pressure differences, without undergoing shock or deformation, thus avoiding pain. Soft and flexible, these plugs are easy to insert and adapt to the shape of the ear canal. Reusable, they are supplied in a storage box to keep them dry and facilitate their transport.
