This is a personal earphone assembly comprised of a flexible, elongate tube having open ends and a central lumen therethrough. Earphones are disposed at each open end of the tube, each earphone having a neck projecting therefrom and a wire passing from the neck, through the lumen, to a central aperture in the tube. In a stereophonic embodiment, the earphone wires run parallel from the central lateral aperture to a plug adapted to engage a stereo jack on a signal source. In a monaural embodiment, the earphone wires join a single double-strand lead to a mono jack. Lateral slits are provided adjacent the open ends of the tube for receipt of the temple ends of a pair of eyeglasses. The portions of the tube between the lateral apertures and the open ends wrap over and around the forward portions of a user's ear, and the earphones lodge in the outer ear canal. The assembly may also be worn without eyeglasses. In an alternative embodiment, a bead slidingly mounted on a doubled portion of the tube allows adjustment for a snug fit. In yet another embodiment, the end portions of the elongate tube have a memory wire disposed therein, for bending the end portions into a configuration for optimally fitting the earphones within the outer ear canal of a user.
