Thin Tubes for HearSource and many other brands hearing aids. These thin tubes are robust, semi-rigid conduits channel sound into your ear canal from the BTE hearing aid’s receiver. Their small thin design makes them nearly invisible and weightless.


Hearing aid thin tubes transmit sound from the hearing aid into your ear canal. They are a core component to the actually delivery of sound from your hearing aid to your ear. Over time, hearing aid thin tubes can become worn, hard, soft, shrink or stretch out of shape. When this happens, they need replaced. Replacing damaged hearing aid thin tubes is important for the proper function of your hearing aid. HearSource stocks a wide variety of hearing aid thin tubes for most hearing aid brands.

It is recommended that you change your tubing every three to six months depending on its use.

Basic BTE Couplings

BTE (Behind-The-Ear) hearing aid couplings are either considered “Standard or Traditional” or “Thin Tube“. The difference in a Standard BTE tube and the Thin Tube design is the diameter of the tube connecting the hearing aid to ear-canal.

Hearing Aid Thin Tube Diagram

Hearing Aid Thin Tube Diagram

Thin Tubes are pre-bent or pre-shaped and serves the purpose to deliver the sound from the hearing aid into the ear and also hold the hearing aid in place on or behind the ear. The thin tube connects to the hearing aid just behind the top and slightly behind the ear. Properly fit, the thin tube should follow the contour of the ear so it fits against the skin until it curves into the ear canal opening.  The thin tube should be snug, but not tight.

If the area at the top of the ear or ear canal becomes tender within the first few hours of wearing the hearing aid, it indicates that the tube is too short.

If you can feel the hearing aids move with normal head movements or if the tube has a tendency to slip out of the ear canal, the tube is too long.

Thin-Tube Open-fittings

The current thin tube open-fittings (or open-ear fittings) refer to the use of a miniature BTE hearing aid that is coupled to an open ear-tip via a 0.8 mm (inner diameter) tube. Ideally, this leaves the ear canal open for its natural resonance.

Hearing aids with thin tubes are an excellent choice for those with extremely small ear canals. Receiver-In-Canal hearing aids require a bit more room in the ear canal. For some, this just isn’t an option. The Thin Tube hearing aid design is the smallest  available option on the market.
