A retaining member for an earphone includes an outer layer of a first material surrounding an inner core of a second material. The retaining member extends from the earphone, and is curved to generally match the shape the antihelix of a human ear. The second material is harder than the first material, providing a stiffness to the retaining member that causes it to apply an upward and backward force against the antihelix when the retaining member is bent to fit under the antihelix of a particular user's ear.

A plate attached to the back shell of an earphone includes an exit cavity corresponding in dimension to and aligned with a first opening through the back shell. A channel in the bottom surface of the plate begins at a point aligned with a second opening through the back shell and ends at an aperture through a side wall of the exit cavity. The channel and the outer surface of the back shell together form a reactive acoustic port from a back cavity enclosed by the back shell to the exit cavity, the first opening through the shell forms a resistive acoustic port from the back cavity to the exit cavity, and the exit cavity couples the reactive acoustic port and the resistive acoustic port to free space without introducing additional acoustic impedance. In some examples, a water-resistant screen covers the upper aperture of the exit cavity.
