The user is able to pivot the body to a comfortable or otherwise desirable position of the body on the outer ear. See FIG. 3A for a more complete description of the outer ear and the manner in which body portion 16 overlies the outer ear. Second body portion 18 is behind the outer ear. In other words, it is located between outer ear 50 and the adjacent portion of head 55, as shown in FIG. 2. Portion 17 connects portions 16 and 18 and is configured to pass over edge 59 of outer ear 50.
