A communication device (200) for use behind the ear comprises a housing having a first section (202) and a second section (206). A sound delivery tube (210) is coupled to the second section of the housing (206). The second section of the housing (206) rotates with respect to the first section of the housing (202) within a prescribed range of angular displacement as to allow user-definable depth adjustability of at least a portion of the sound delivery tube (210) into an ear canal (104). Optionally, the first section of the housing (202) rotates with respect to the second section of the housing (206) to provide a better fit to the shape of the head at the temporal/mastoid plate 120.
