Abstract
Abstract The present invention relates in general to ear muffs and in particular to an ear muff for headphones for portable radios and cassette players and the like, which may be easily removed or exchanged. The ear muff is constructed with a support cup that is covered by fabric, wool or other material which engages, and at least partially surrounds the ear of the wearer to keep it warm in cold weather. The band or strap for the headphone speaker is captured by two overlapping flaps that extend over the band or strap which are preferably locked together by mating plastic loop and hook type fasteners.
