Abstract
An earphone comprises an inner shell, a stem and a pivot connection. The inner shell has a generally circular periphery shaped to at least partially fit in a user's concha. The stem is mounted to the inner shell at a position spaced from a rotational center of the inner shell and supports a wire leading to the inner shell. The inner shell and the stem are rotatable relative to each other by the pivot connection to configure the earphone to fit the user's ear with the shell member positioned at least partially in the user's concha and the stem positioned exteriorly along an intertragic notch of the ear.
