1. A semi-permanent hearing device adapted to be inserted by a professional entirely within a wearer's ear canal past the aperture thereof for long-term use therein such that no portion of said hearing device extends into the wearer's concha cavity, the device comprising: a sealing retainer adapted to be seated in the bony portion of the ear canal along the longitudinal axis and in direct contact with the walls thereof when said device is fully inserted within the ear canal of the wearer; a receiver assembly, including a receiver with a medial end for supplying acoustic signals to the tympanic membrane of the wearer, carried by the sealing retainer; a microphone assembly including a microphone with a medial end for receiving incoming acoustic signals, said microphone assembly located in spaced relation to the sealing retainer that carries the receiver assembly and configured to be positioned entirely within the ear canal past the aperture thereof when the hearing device is inserted entirely therein and to be supported entirely within the ear canal with minimal or no contact with the walls thereof; and a self-contained battery assembly, for powering said hearing device, having a battery with a medial end and a lateral end, the medial end of the battery being closer to the medial end of the receiver than to the medial end of the microphone; wherein said hearing device is inserted entirely in the ear canal past the aperture thereof such that no portion of said hearing device extends into the wearer's concha cavity and positioned medially in close proximity to the tympanic membrane by a professional for extended wear in the ear canal without resorting to daily insertion and removal of said hearing device by the wearer.
