1. A hearing aid for use in an ear canal, comprising:
- a main axis;
a core module including a front end surface approximately centered on the main axis, a rear end surface approximately centered on the main axis, a lateral surface coupled between the front end surface and the rear end surface, a hearing aid circuit including a receiver, a case housing the hearing aid circuit, and a first receiver port on the case, the first receiver port including an opening providing for acoustic communication with the receiver, the opening on the lateral surface and remote from the main axis; and
a soft sleeve configured to accommodate at least a portion of the core module, the sleeve including a wall and a second receiver port on the wall on or near the main axis when at least the portion of the core module is placed in the sleeve such that the core module and the sleeve are approximately coaxial about the main axis, the second receiver port providing for transmission of sound from the receiver through the first receiver port and including a plurality of boomerang ports.

Abstract
A hearing aid kit includes a standard fit, completely-in-canal (CIC) hearing aid and a hearing aid tool set. The CIC hearing aid is for extended use and includes a core module inserted into a sleeve. The core module and the sleeve each include various features providing for a minimum overall size, ease of insertion, removal, and cleaning, and enhanced sound transmission. The tool set is configured to be stored and carried in a single piece and provides for adjustment and cleaning of the CIC hearing aid. Open ear fits and occlusive ear fits are possible using different sleeves.
