Bernafon Viron BTE 105 – Compatibility Guide & Accessories | Japebo

Looking for the right accessories for your Bernafon Viron BTE 105? This guide helps you confirm compatibility and choose the correct parts, so you can buy with confidence. Bernafon BTE models can use different fittings depending on how your hearing aid was set up (for example: thin tube with a dome, or an earmould), so identifying your current setup is the fastest way to choose correctly.

What “BTE” means for Bernafon Viron BTE 105 accessories
BTE (Behind-The-Ear) hearing aids sit behind the ear and deliver sound into the ear canal through either:

A thin tube + dome (a soft tip that sits in the ear canal)
An earmould (custom mould connected to tubing)

Because both fittings exist for BTE devices, the correct accessory depends on what you’re wearing today—not only the hearing aid name.

How to identify which parts you need
Use these quick checks to match the right accessory type for your Bernafon Viron BTE 105:
1) Check what sits in your ear

Soft silicone tip (dome): you will typically need replacement domes and possibly the thin tube or retention parts.
Hard or custom-shaped mould: you will usually need tubing replacements and cleaning supplies rather than domes.

2) Look at the connection at the hearing aid
If you see a thin, clear tube clicking or locking onto the hearing aid, your setup is likely a thin-tube BTE fitting. If you see thicker tubing going to a mould, you’re likely using an earmould setup.

3) Match size and side (left/right)
Many BTE parts come in left/right versions and different lengths. If your current tube has markings, copy them. If not, compare the shape and length to your existing part to avoid a poor fit.

Common accessory types for Bernafon Viron BTE 105
Depending on your fitting, these are the most common items people replace or top up:

Domes: come in different styles (open/vented/closed/power) and sizes. The correct dome affects comfort, feedback (whistling), and sound balance.
Thin tubes / tubing: can harden over time, become discoloured, or stop fitting snugly—leading to comfort issues or sound changes.
Cleaning & care: wipes, drying solutions, and tools help prevent moisture and blockage-related problems.
Batteries: if your Viron BTE 105 uses disposable batteries, the correct size must match the marking on your current battery (colour-code can help too).

If you’re unsure which category applies, start by identifying whether you use a dome or an earmould—that single step usually determines the correct path.

How to choose the right dome (if you use domes)
If your Bernafon Viron BTE 105 uses domes, choosing the right type and size reduces whistling, improves comfort, and helps keep sound stable.
Choose the dome style based on your current fit

Open-style domes: often feel more breathable and can sound more natural for many users, but may increase feedback if the fit is too loose.
More closed/power styles: can improve bass and reduce feedback, but may feel more occluding.

Choose the correct size
Sizes are typically small/medium/large (or measured in mm). Use your existing dome as the best reference. If your dome slips out or whistles, you may need a different size—or a different style.

Common problems (and what to replace first)
Whistling / feedback
Most often caused by a poor seal (wrong dome size/style), a tube that doesn’t sit correctly, or blocked sound outlets. Try replacing the dome first, then check the tube/tubing.

Sound is weak or muffled
Often caused by moisture, earwax blockage, or hardened tubing. Replace the tube/tubing if it’s stiff or discoloured, and ensure the sound path is clean.

Discomfort or itching
Try a different dome size or style. If irritation persists, consider whether a mould-based solution is required—your hearing care professional can advise.

FAQ: Bernafon Viron BTE 105 compatibility
Are all Bernafon BTE accessories compatible with Viron BTE 105?
No. Compatibility depends on the fitting system (thin tube vs earmould tubing) and the specific connector/size. Always match the accessory to your current setup.

How often should I replace domes or tubes?
Domes are typically replaced more frequently for hygiene and fit. Tubes/tubing are replaced when they become stiff, discoloured, loose, or when sound/comfort changes.

How do I know if I use a dome or a mould?
If there is a soft silicone tip in the ear canal, you use a dome. If there is a custom-shaped hard piece filling part of the ear, you use an earmould.

What if I’m between dome sizes?
Choose the size that gives a secure, comfortable fit without pressure. If you get whistling or the dome slips, a different size or a more closed style may be needed.
