Rexton MyCore BTE Series Accessories & Compatibility Guide | Japebo
Looking for the right Rexton MyCore BTE series accessories? This guide helps you identify what fits, avoid mismatches, and choose the correct consumables and spare parts for your Rexton MyCore BTE (Behind-the-Ear) hearing aids. Because compatibility can vary by model and fitting style (classic BTE vs. slim-tube/receiver-style fittings), we’ll explain what to check before you buy.
What “Rexton MyCore BTE” means (and why it matters for accessories)
BTE stands for Behind-the-Ear. In the Rexton MyCore family, BTE instruments can be fitted in different ways:
Classic BTE with earmould: sound travels through a tone hook and tubing into a custom earmould.
Slim tube / thin tube fitting: a thin tube and small dome sit in the ear canal.
Receiver-in-canal style (RIC/RITE) in some families is separate from “BTE” accessories (different receivers and retention parts).
That’s why the same “MyCore” name doesn’t automatically guarantee that every accessory fits every MyCore device. The correct accessory depends on the exact housing type and coupling (mould, tube + dome, or receiver).
Which accessory types are most common for Rexton MyCore BTE fittings?
Most customers shop for one of these categories when maintaining a Rexton MyCore BTE series fitting:
Domes / eartips (for thin-tube fittings): open, closed, tulip, or power-style domes depending on your loss and comfort needs.
Tubes / thin tubes (for slim-tube fittings): must match the correct connector type and ear side (left/right) where applicable.
Wax protection: wax guards/filters are common for receiver- or tube-based fittings where wax can block the sound outlet.
Earmould tubing & hooks (for classic BTE + mould): tubing diameter and hook style must match the instrument and mould.
Batteries (for battery-powered versions): the battery size depends on the exact MyCore BTE model.
Cleaning & care: cleaning tools, drying solutions, and disinfecting wipes help reduce moisture and blockage issues.
How to confirm compatibility for Rexton MyCore BTE series accessories
Use these checks to make sure you’re on the right product:
1) Identify your exact fitting type
Start by looking at what sits inside your ear:
If you have a custom earmould, you likely need earmould tubing (and possibly a tone hook).
If you have a small silicone dome, you likely need domes and a thin tube (and possibly wax protection depending on the design).
2) Match size and side (where relevant)
Many parts come in multiple sizes and sometimes left/right versions:
Domes are primarily size-based (e.g., small/medium/large) and type-based (open vs. more closed for more power).
Thin tubes may be sized by length and sometimes ear side.
3) Check the product code / packaging from your current parts
The fastest way to get an exact match is to compare the printed code on your existing packaging, invoice, or the part itself (when marked). If you’re unsure, choose the option that best matches what you currently wear, then adjust only if you’re intentionally changing fit or sound.
Choosing the right Rexton MyCore BTE domes (if your fitting uses domes)
Domes influence both comfort and sound (especially bass/occlusion and feedback). As a rule of thumb:
Open domes: more natural airflow and less occlusion; often used for mild to moderate losses.
Closed domes: more low-frequency support; can help if sound feels thin or if you need more amplification.
Power domes: most sealed; can help with stronger losses but may feel more “plugged.”
If you’re happy with your current sound, the safest approach is to replace with the same type and size. If you’re experiencing feedback (whistling) or weak sound, a different dome style/size may help—but changes should ideally be guided by your hearing care professional.
Common problems (and what accessory change usually fixes them)
Sound is weak or muffled
Replace wax protection (if used)
Replace dome or tube if it’s blocked, stiff, or discolored
Whistling / feedback
Try a better seal (often a slightly larger dome or a more closed dome type)
Check that the dome is fully seated and not torn
Fit feels loose or irritating
Adjust dome size/type
Replace worn domes (silicone can harden over time)

FAQ – Rexton MyCore BTE accessories
Are all Rexton MyCore accessories interchangeable across the MyCore range?
Not always. “MyCore” is the family name, but accessories depend on the device style (BTE with mould vs. thin-tube) and the connector/size system used.
How often should I replace domes or tubes?
Domes are typically replaced regularly for hygiene and fit (often every few weeks to monthly, depending on wear and earwax). Tubes are replaced when they stiffen, discolor, or don’t stay securely connected.
What should I do if I don’t know my dome size?
If possible, check your old packaging. Otherwise, compare the dome diameter to a ruler and choose the closest match, or select the size you currently wear if you’re reordering from the same product line.
Do Rexton MyCore BTE hearing aids use wax filters?
Some fittings do (especially where the sound outlet can be blocked by wax). Whether you need wax protection depends on your exact coupling (tube/dome setup) and the parts your hearing care professional fitted.
Which battery size does my Rexton MyCore BTE use?
Battery size varies by the exact MyCore BTE model. Check the marking inside the battery door, your manual, or your current battery packaging to confirm the correct size before ordering.
