Alpine FlyFit earplugs are designed to make your trip or flight as comfortable as possible. Wearing earplugs during a flight regulates the unpleasant pressure on the eardrums. The filters work like an air valve and ensure a gradual and constant pressure balance between the outer air and your middle ear. Moreover, the FlyFit earplugs reduce noise from your surroundings to manageable levels. The FlyFit earplugs guarantee a relaxed flight and a comfortable start to your holiday.
