Oticon Optim BTE 105 – Tube & Earhook Compatibility Guide | Japebo

If you’re looking for a replacement Oticon Optim BTE 105 tube or earhook, this page helps you confirm compatibility and choose the correct part before you buy. The Optim BTE 105 is a specific Oticon behind-the-ear (BTE) fitting component, and small variations (size/shape/connection) can affect comfort, sound, and retention. Use the guide below to make sure you’re on the right product page and selecting the right replacement.

What is the Oticon Optim BTE 105?
Oticon Optim BTE 105 refers to a BTE fitting part used on certain Oticon hearing aid setups. Depending on your configuration, it may be used as a hook/tube-style connection that guides sound from the hearing aid into the earmold or tubing system. Replacing it with the correct Optim variant helps maintain the intended acoustic performance and a secure, comfortable fit.

Which hearing aids are compatible with Oticon Optim BTE 105?
Compatibility is determined by the connection type on your Oticon BTE hearing aid and the fitting system you use (e.g., standard tube + earmold). The most reliable way to confirm you need the Optim BTE 105 is to match:

The name/number printed on the current part or packaging (e.g., “Optim BTE 105”).
The physical shape (bend/angle/length and how it locks onto the hearing aid).
Your hearing care provider’s fitting note (often lists the exact hook/tube specification).

If your current part is worn, discolored, or cracked, it can still be used for comparison—focus on the connection end that attaches to the hearing aid body and any visible marking.

How to identify that you need the Optim BTE 105 (and not a similar Oticon part)
Oticon has multiple BTE fittings that can look similar. To avoid ordering the wrong part, check the following:

Marking/label: Look for “105” or the full Optim model reference on the part or original bag.
Attachment method: Confirm whether it is a click-on/lock-on style or a different coupling design.
Tube interface: Some variants accept different tube sizes or have different tube seating depth.

If you’re unsure, compare your current part to the product photos on Japebo and match the connection geometry as closely as possible.

How to choose the right replacement
When selecting an Oticon Optim BTE 105 replacement, the goal is to keep the same acoustic and physical setup you have now. In practice, choose based on:

Exact model match: Optim BTE 105 should match your current fitting reference.
Left/right orientation (if applicable): Some BTE fittings are side-specific—keep the same side as your existing part.
Your earmold/tube system: If you use an earmold with standard tubing, ensure you keep the same tube interface to avoid leaks or poor retention.

Common problems and quick fixes
Whistling (feedback) after replacing the part
Feedback is often caused by a small leak or a poor seal. Ensure the Optim BTE 105 is fully seated on the hearing aid and that the tube is firmly connected with no gaps or cracks. If the earmold tubing is loose, it may need re-tubing.

Sound is weaker or “different”
A slightly different hook/tube style can change acoustics. Double-check you selected Optim BTE 105 (not a visually similar Optim variant). Also inspect for blockage in the tubing or moisture buildup.

The fit feels uncomfortable or the hearing aid won’t sit correctly
Incorrect angle/length or a mismatched part can change how the BTE sits behind the ear. Compare the bend and attachment points to your original part to confirm it’s the same model.

When should you replace your BTE tube/earhook?
Replace the Oticon Optim BTE 105 if you notice:

Yellowing, stiffness, or cracks
Loose attachment to the hearing aid
Reduced sound quality or intermittent sound
Increased feedback that wasn’t present before

Regular replacement helps keep sound stable and reduces daily frustrations.

FAQ: Oticon Optim BTE 105
Is “Oticon Optim BTE 105” the same as a standard earhook?
It’s a specific Oticon BTE fitting reference. While it may function like an earhook/tube connector, it should be treated as a model-specific part—match the reference number for best results.

Can I use Optim BTE 105 on any Oticon BTE hearing aid?
Not necessarily. Compatibility depends on the coupling/connection type on your hearing aid and the fitting system. The safest approach is to match the exact part number from your current setup.

What if I can’t find the number on my current part?
Use the product photos to compare the connection end and overall geometry, or refer to any old packaging. If you still can’t confirm, your hearing care provider can identify the correct fitting reference.

Will replacing this part fix feedback?
It can help if feedback is caused by cracks, looseness, or poor sealing in the old fitting. If feedback persists, the issue may be with the earmold fit, tubing, or hearing aid settings.
