Rexton M-Core RIC Series Accessories & Compatibility Guide | Japebo

If you use a Rexton M-Core RIC Series hearing aid, choosing the correct accessories matters for both comfort and sound quality. This guide explains the most common Rexton M-Core RIC Series accessories, how compatibility typically works, what to check before you buy, and how to troubleshoot common fit and sound problems.

What is the Rexton M-Core RIC Series?
Rexton M-Core RIC (Receiver-In-Canal) hearing aids place the speaker (receiver) in the ear canal, connected by a thin wire to the hearing aid behind the ear. Because the receiver and ear-piece sit in the ear, the small wearable parts (like domes, wax protection, and receivers) are the accessories most commonly replaced.

Which accessories are typically used with Rexton M-Core RIC hearing aids?
Most users will need one or more of the following accessory types over time:

Domes (ear tips): affect comfort, retention, and acoustics.
Receivers (speaker units): come in different power levels and wire lengths.
Wax filters / wax guards: protect the receiver opening from earwax and moisture.
Retention locks (sport locks): help keep the receiver stable in the ear.
Cleaning accessories: help extend receiver and dome life and keep sound clear.

How compatibility works for Rexton M-Core RIC Series accessories
With RIC models, compatibility is usually determined by the receiver platform used by your hearing aid. This matters because the receiver connection, wax protection system, and which domes fit can vary between platforms and generations.
Before ordering, verify these three points:

Your exact model/family: confirm it is within the Rexton M-Core RIC Series.
Your receiver details: the wire length and power level (e.g., standard vs power) should match what you already use.
Your current ear-piece system: note whether you use domes or a custom earmold, and what wax filter type you currently have.

If you are unsure, the safest approach is to compare the shape/name of the wax guard or dome you currently use, or check the receiver label/packaging from your last replacement.

Domes for Rexton M-Core RIC Series: types and how to choose
Domes are small silicone tips that attach to the receiver and sit in your ear canal. The right dome improves comfort, reduces feedback (whistling), and ensures you get the sound your fitting is designed for.

Common dome styles

Open domes: feel airy and reduce the “blocked” sensation; often used for mild-to-moderate losses.
Closed domes: seal more than open domes; can improve bass and reduce feedback.
Power domes: create the strongest seal; often used for more severe losses or when feedback is an issue.

How to pick the right dome size
Dome size affects both comfort and sound. Use your current dome size as the starting point. If you have any of the issues below, your size or type may need adjustment:

Falls out / feels loose: consider a larger size or adding a retention lock if supported.
Sore ear canal: consider a smaller size or a more open style (if appropriate for your fitting).
Whistling (feedback): a more sealing dome (closed/power) or a better size can help.

Receivers for Rexton M-Core RIC Series: what to check
The receiver is the part that produces sound in your ear. Receivers wear out over time due to moisture, earwax, and everyday use.

Receiver power level
Receivers are available in different power levels. Using the wrong power level can affect sound quality and may not match your programmed fitting. If you are replacing a receiver, match the same power category you currently have unless your hearing care professional has changed your fitting.

Receiver wire length (left/right)
RIC receiver wires come in different lengths and are side-specific. To avoid an uncomfortable fit or poor retention, choose the same length and side (L/R) as your current receiver.

Wax filters (wax guards): why they matter and when to replace
Wax filters protect the receiver opening from earwax and debris. A clogged wax filter is one of the most common reasons for weak, muffled, or intermittent sound in RIC hearing aids.

Typical signs your wax filter needs changing

Sound is suddenly weaker or duller
One side is noticeably quieter than the other
Sound cuts in and out (especially after being in a warm/humid environment)

If changing the wax filter does not help, the dome may be blocked, or the receiver may need replacement.

Common problems with Rexton M-Core RIC accessories (and fixes)
1) Whistling or feedback

Check the dome is fully seated on the receiver.
Try a fresh dome (silicone can loosen over time).
Consider a more sealing dome type (closed/power) if recommended for your hearing loss.

2) Muffled sound

Replace the wax filter first.
Inspect and replace the dome if blocked or worn.
If still muffled, the receiver may be failing and could need replacement.

3) Poor fit or the receiver keeps moving

Try a different dome size.
If compatible, add/replace a retention lock.
Confirm you have the correct receiver wire length.

Once you know your current dome type/size and your receiver details (side, length, and power level), you can confidently choose the correct Rexton M-Core RIC Series accessories. Replacing domes and wax filters regularly helps maintain comfort and clear sound, and keeping a spare receiver can reduce downtime if sound issues occur.

FAQ: Rexton M-Core RIC Series accessories
How do I know which dome fits my Rexton M-Core RIC hearing aid?
The most reliable method is to match the dome style and size you currently use. If you don’t know it, compare the shape to your existing dome or check any previous packaging from replacements.

Can I use any wax filter with Rexton M-Core RIC receivers?
No. Wax filters are not universal. You must use the wax guard type designed for your receiver platform. If you’re unsure, identify the exact wax filter style currently installed before ordering.

When should I replace domes and wax filters?
Many users replace domes every few weeks to months depending on wear, and wax filters whenever sound becomes weak/muffled or at regular intervals based on earwax production and environment.

Should I replace the receiver if sound is weak?
Start by replacing the wax filter and checking the dome for blockage. If sound is still weak or intermittent, the receiver may be damaged and could need replacement.
