QUIES Air Travel are essential for sensitive ears on any plane or train journey or high-altitude trek. These earplugs are designed for people who suffer from ear pain during the pressure change in the airplane. Thanks to their ceramic filter, the QUIES Air Travel regulate the flow of air through the ear during pressure changes (during take-off and landing of an airplane or during Fahrt through a tunnel). The eardrum then gradually adapts to the pressure differences without suffering shock or deformation, avoiding pain. The plugs are reusable and come in a storage box to keep them dry and easy to transport.
