A cushion includes a first material and a second material and is formed into a first region and a second region. The first region defines an exterior surface shaped to fit the concha of a human ear. The second region defines an exterior surface shaped to fit the ear canal of a human ear. The first and second regions together define an interior surface shaped to couple the cushion to acoustic elements of an earphone. The first material occupies a first volume adjacent to the interior surface. The second material occupies a second volume between the first material and the first and second outer surfaces. The first and second materials are of different hardnesses.
