Abstract: An improved ear muff that is snappably engageable with the ear of the wearer. It includes an outer cover and an inner snappable annular actuating element form-fitted within said outer cover, the inner annular actuating element comprising a semi oval generally c-shaped closable ribbon-like member having closing projections and mating apertures to change the shape from that of a "c" to essentially that of an "o". When in the open, or "c" shape, the two ends of the ribbon which are opposed are non- parallel thus forming a truncated V-shaped space leading into the interior of the c, and the ribbon is essentially planar or partially curved. When in the closed, or "o" shape, the closing projections mate within the mating apertures thereby eliminating the truncated V-shaped space and causing the ribbon to assume or increase an arcuate shape. Provision is additionally made for optional inclusion of one or more electrical-to-audio transducers mounted within the muffs.
