Abstract
An earphone device configured to be removably secured within an ear of a user includes a main body having a base wall and a longitudinal axis, a first projection extending outwardly away from the base wall perpendicular to the longitudinal axis, and a second projection formed at a position spaced apart from the first projection and extending outwardly away from the base wall parallel to the longitudinal axis. The second projection has a tearshaped body tapering from a distal first end toward a proximal second end which defines a single connection point with the base wall. An opening is formed through the tearshaped body. In a use position, the first projection extends inwardly toward the internal cavity of the ear and the second projection deforms to conform to the antihelix of the ear, such that movement of the earphone device relative to the internal cavity of the ear is limited.
