Abstract
A protective ear appliance including two ear protectors with a band and a slidable coupling between the band and the ear protectors. The band encircles a portion of a wearer's head, has a curved shape with two ends and inner and outer curved surfaces. There is a slidable coupling between each of the ear protectors and the band so that each ear protector can slide independently with respect to the band to adjust the distance between the two ear protectors along the band so that the ear protectors can seat in the wearer's ears. The band can be formed with a central band hingedly coupled to the two end band portions. The ear protectors are coupled to the end band portions and slide relative to the end band portions. The protective ear appliance is designed to be worn with the central band around the back of the wearer's head.
