Abstract
An adjustable, dual speaker element earphone. One of the speaker elements is sized to fit into the cavum concha of the listeners ear and the other element is not. A hinged joint may allow the larger speaker element may be rotated about a vertical axis of the hinged joint so that the larger speaker element can be rotated towards or away from the listener's ear. The speaker elements may be connected such that sounds produced by both speaker elements emanate from different respective sound openings defined in a surface of the smaller speaker element. Also, one or both of the speaker elements may be operably connected to a hanger bar that is sized and configured to rest on an upper portion of the listener's ear.
