The present invention is directed to a headphone or an earpiece that includes a cushion that advantageously allows for improved comfort, sound quality, and stability in the ear. The cushion includes an inner cavity, an ear-canal aperture and a tip portion, wherein the inner cavity of the cushion accommodates a nozzle portion of a housing within the cavity, and the axis of the inner cavity is substantially parallel to the first axis, and wherein the ear-canal aperture opens toward the ear canal of the user's ear when the headphone or the earpiece is worn by the user. A speaker element is positioned inside the nozzle portion of the housing, and the center of mass of the headphone is shifted close to a center plane of the cushion.
