The earphone includes a base that is positioned proximate an outer surface of the tragus and anti-tragus when the earphone is mounted to the ear. A speaker housing at least partially contacts the acoustic meatus of the ear and includes a speaker cover positioned proximate the canal when the earphone is mounted to the ear. First and second tragus lobes extend from the base generally toward the speaker housing. The first and second tragus lobes are spaced from and positioned on generally opposite lateral sides of the speaker housing. The anti-tragus being held between the first tragus lobe and the base when the earphone is mounted to the ear and the tragus being held between the second tragus lobe and the base when the earphone is mounted to the ear.
