An earphone (16) is disclosed capable of secure carriage on the ear (18) of a user (12), even during vigorous physical activity. The earphone (16) includes a light-weight audio speaker (40) supported on a flexible, open-looped earpiece ergonomically tailored to cradle the ear (18) without significant resilient deformation. The earphone (16) is made of a hook portion (64) curved to fit against the head (20) of the user (12) over the top of the base (62) of the ear (18). Integrally formed at the forward end (66) thereof is a boom portion (70), which projects downwardly and rearwardly above the tragus (46) to the concha (48) terminating at a remote end (72) from which the speaker (40) is permanently or detachably supported. A curved brace portion (74) integrally formed with the hook portion (64) depends downwardly from the rearward end (68) of the hook portion (64) in close conformity with the back surface (50 ) of the base (62) of the ear (16) to terminate behind the earlobe (30). An electrical conductor (84) longitudinally disposed within the earphone (16) is electrically connected at one end thereof to the speaker (40). At a point on the earphone (16) below and behind the earlobe (30) the other end of electrical conductor (84) is either permanently or detachably connected through an audio lead (24) to an audio signal source (14).
