A behind the ear communication device (200) has a housing (205) with a form factor to provide a comfortable fit across a wide variety of users. Particularly, the housing (205) is a hook shaped member having an inner curved surface (261) defined by first and second arcs (272, 271) that merge, in tangential fashion, to form a contiguous surface for interfacing with the ear. The first arc (272) has a radius of between 0.826 and 0.876 centimeters, and the second arc has a radius of between 3.24 and 3.75 centimeters.
