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 or sore spots.
Choose tubing based on:
Thickness: many super power BTE fittings use thicker tubing for stability
Fit: it should sit firmly on the earhook and on the earmould without forcing
If your tube looks yellow/brown, feels stiff, or no longer sits comfortably, it’s typically time to replace it.
Common problems (and what accessory to check first)
Whistling / feedback
Most often caused by sound leakage. Start by checking:
Is the tubing hardened or shrunken?
Is the earhook cracked or is the tube connection loose?
Does the earmould still fit well (no gaps)?
Sound is weaker than normal
Check the sound path first. Moisture or blockage in the tubing or earhook can reduce output. Swapping to fresh tubing (and ensuring the hook is clean and intact) often resolves the issue.
Intermittent sound or crackling
Moisture is a common culprit for BTE systems. Consider care accessories designed to keep equipment dry and clean, and make sure tubing and hook connections are secure.

FAQ: Oticon Dynamo BTE SP accessories
Are Oticon Dynamo BTE SP accessories the same as other Oticon BTE models?
Some parts can be similar, but BTE hooks and tubing can vary by model and power class. To avoid mismatches, confirm “Dynamo BTE SP” and match the connection style you currently use.
Does Oticon Dynamo BTE SP use domes?
Most Dynamo BTE SP fittings use an earmould with tubing rather than domes (domes are more common on RIC and slim-tube fittings). If you wear an earmould, focus on earhooks, tubing, and care items.
How do I know if I need a new earhook?
If tubing no longer fits tightly, feedback has increased, or the hook shows wear (cracks, discoloration, rough edges), replacing the earhook is a good first step.
How often should I change the tubing?
It depends on wear, moisture exposure, and skin oils. Replace tubing when it becomes stiff, discolored, uncomfortable, or when you notice more feedback or a looser fit.
I’m not sure what to choose—what information helps most?
The quickest way is to compare your current parts: a photo of the earhook and tubing connection, plus confirmation that the device is Oticon Dynamo BTE SP, usually makes selection straightforward.
