Oticon Dynamo BTE SP accessories & compatibility guide | Japebo

Looking for accessories for the Oticon Dynamo BTE SP? This guide helps you identify which parts fit your hearing aid, what to choose, and how to avoid common compatibility mistakes. Oticon Dynamo BTE SP is a Behind-The-Ear Super Power model, and the right accessories (especially tubing and earhook parts) are essential for comfort, stable sound, and reliable performance.

What accessories are typically used with Oticon Dynamo BTE SP?
Because Oticon Dynamo BTE SP is a powerful BTE hearing aid designed for higher output needs, the most common accessory needs are related to the sound path from the hearing aid to the ear (earhook + tubing) and day-to-day maintenance items.
Typical accessory categories include:

Earhooks (tonehooks) – the hook on the hearing aid where the tube connects
Tubing – standard or thick BTE tubing used with an earmould
Earmould-related parts – items tied to mould/tube setups (varies by mould type)
Cleaning and care products – to reduce moisture and wax-related issues

Compatibility: how to make sure you choose the correct part
For Oticon Dynamo BTE SP accessories, compatibility is usually determined by the physical connection type (earhook and tubing size) rather than by “left/right” variants or dome styles that are common on RIC models.

1) Confirm the exact model name
Check your documentation or the printing on the device to confirm it says Oticon Dynamo BTE SP. Accessories are often similar across BTE power devices, but small differences in hooks or tube dimensions can matter.

2) Identify your current setup (earhook + tube + earmould)
Most Dynamo BTE SP users wear an earmould with tubing. If you already have a working setup, the easiest way to buy correctly is to match the current parts:

Compare the shape of the earhook (length/angle)
Match the tube thickness (standard vs thick)
If the old tube fits tightly on the hook and mould, choose the same type

3) When in doubt: replace like-for-like
If you are unsure about sizes, start by replacing the same part you are currently using (e.g., the same style earhook or the same tubing type). This is the safest way to keep acoustics and comfort consistent.

Choosing the right Oticon Dynamo BTE SP accessory (practical tips)

Earhooks: when and why to replace
Replace the earhook if you notice any of the following:

Loose tubing that slips off more easily than before
Cracks, discoloration, or sharp edges
More whistling (feedback) after the earmould and tube have been checked

A worn or damaged earhook can cause poor sound direction, leakage, and reduced comfort.

Tubing: how to select and how often to change it
Tubing affects both comfort and sound. Over time it can harden, discolor, and shrink slightly, which can pull on the earmould and cause feedback
