Signia Pure 312 AX RIC – Accessories & Compatibility Guide | Japebo
If you use Signia Pure 312 AX RIC hearing aids, choosing the right accessories matters for comfort, sound quality, and reliability. This guide helps you identify compatible Signia Pure 312 AX RIC accessories—such as domes, wax filters, receivers and batteries—so you can replace parts confidently and avoid ordering the wrong type.
What is the Signia Pure 312 AX RIC, and why accessories must match
The Signia Pure 312 AX RIC is a receiver-in-canal (RIC) hearing aid that uses a thin speaker wire (receiver) leading to your ear. Many wearable parts are “small but specific”: different dome systems and wax protection types are not always interchangeable, and the wrong choice can cause feedback (whistling), poor sound, irritation, or reduced volume. The safest approach is to match accessories to what your current parts look like—or to the exact model family (Pure 312 AX).
Compatible accessory types for Signia Pure 312 AX RIC
Domes (ear tips)
Domes sit on the end of the receiver and affect both comfort and sound/openess. If your hearing aids feel loose, whistle, or sound “thin,” the dome style and size is often the reason.
Common dome styles you may see for Signia RIC fittings:
Open domes – More ventilation and a natural feel; often used for mild to moderate losses.
Closed/Double domes – More sealing and bass; can reduce squealing if you experience feedback.
Power domes – Maximum seal; typically used when more amplification is needed.
How to choose: Start by matching the type (open/closed/power) and then the size. If you are between sizes, the better fit is usually the one that seals gently without pressure. If the dome causes soreness, size down or switch to a more open style.
Wax filters / wax guards
Wax protection keeps earwax and moisture from entering the receiver. A clogged wax filter is one of the most common causes of suddenly weak or distorted sound.
How to choose: Wax filters come in specific systems. To avoid mistakes, compare the filter you currently use (shape/color and dispenser style) and choose the same type. If you are unsure, remove one used filter and match it visually.
When to replace: If sound drops, becomes dull, or one side is quieter than the other—even after cleaning the dome—replace the wax filter first.
Receivers (speakers) and receiver wires
In a RIC model like the Signia Pure 312 AX, the receiver is a key replaceable part. Compatibility depends on the receiver system used by your fitting and the correct length (how far it reaches) and power level (often coded by strength).
How to choose:
Match receiver type/system to your current receiver (do not assume different Signia families share the same receiver).
Match length (left/right and size/number) so the wire sits comfortably and securely.
Match power level (e.g., standard vs higher power) as prescribed—changing power can affect fit, sound, and feedback.
Tip: If only one side is consistently quieter and wax filters are clean, a receiver replacement is a common fix.
Batteries (size 312)
The Pure 312 AX uses size 312 hearing aid batteries. If you experience short battery life, ensure the battery is fresh and stored correctly, and check that moisture isn’t affecting the contacts.
Tip: After removing the sticker tab, let the battery “air up” for about a minute before inserting—it can improve performance.
How to know you’re buying the right Signia Pure 312 AX parts
Use these quick checks before ordering:
Model match: Confirm your model is Signia Pure 312 AX RIC (often written on your paperwork or in the app).
Visual match: Compare your current dome and wax filter to product photos (shape is more reliable than memory).
Receiver details: If buying a receiver, verify left/right, length, and power markings on your existing receiver.
Common problems and the accessory that usually fixes it
Whistling/feedback: Try a larger dome, a more closed dome, or check the dome is fully seated.
Sound is weak or muffled: Replace the wax filter; also check for moisture and a blocked dome.
One side cuts out: Replace the battery first, then the wax filter; if it persists, the receiver may be failing.
It feels itchy or sore: Consider a smaller dome, a more open dome, or take short breaks to let the ear recover.

FAQ: Signia Pure 312 AX RIC compatibility
Are all Signia domes compatible with the Signia Pure 312 AX RIC?
No. Dome systems can differ between Signia model families and receiver types. The safest option is to match the dome style and connection used on your current receiver.
How often should I change wax filters?
It depends on wax build-up and wear. Many users replace them every few weeks, but you should change them immediately if sound becomes weak, dull, or intermittent.
What battery does the Signia Pure 312 AX use?
The Signia Pure 312 AX uses size 312 hearing aid batteries.
How do I know which receiver length I need?
Receiver length is usually marked on the receiver/wire (and differs for left/right). Match the markings from your existing receiver to order the same length.
My hearing aid is quiet even after changing the wax filter—what next?
Check the dome for blockage and confirm the battery is fresh. If the issue remains on one side, the receiver is a common next replacement step.
