Signia Nx RIC Series Accessories & Compatibility Guide | Japebo
If you’re looking for Signia Nx RIC series parts, you’re usually trying to solve one of three problems: comfort (the fit isn’t right), sound quality (it’s blocked, weak, or whistling), or maintenance (wax and moisture build-up). This guide explains the most common Signia Nx RIC series accessories, what they do, and how to choose the right option so you can order with confidence.
What “RIC” means for Signia Nx accessories
RIC (Receiver-in-Canal) hearing aids use a small speaker (the receiver) placed in the ear canal and connected to the hearing aid by a thin wire. Because of that design, most Nx RIC users will typically replace or buy accessories in these categories:
Domes (ear tips) for comfort, retention, and sound balance
Wax filters / wax guards to protect the receiver from earwax
Receivers (speakers) if sound drops out or the wire is damaged
Cleaning & care items to reduce moisture and keep performance stable
Most-used Signia Nx RIC accessory types (and what they do)
Domes for Signia Nx RIC
Domes are the soft tips that sit in the ear canal. They affect both comfort and sound. In general, you’ll see these common styles:
Open domes: More ventilation and a more “natural” feel; often used for mild-to-moderate fittings
Closed domes: Less ventilation; can help increase low-frequency amplification and reduce feedback in some cases
Power / double domes: More seal; often used when more amplification is needed
If your hearing aid feels loose, whistles (feedback), or sounds thin/too sharp, the dome type and size are common causes.
Wax filters / wax guards for Signia Nx RIC
Wax filters protect the receiver opening from wax and debris. A clogged filter is one of the most common reasons for:
Sudden drop in volume
Muffled sound
Intermittent sound (works sometimes, then cuts out)
If changing the battery (or charging) doesn’t help, the next step is usually to check and replace the wax filter. Using the correct wax filter type is important—different receiver ends take different filters.
Receivers (speakers) for Signia Nx RIC
The receiver is the small speaker that sits in the ear canal. Receivers are typically chosen by:
Power level (set by your fitting)
Wire/length (for correct fit over the ear)
Left vs right
Common signs you may need a receiver replacement include cracking wire damage, sound dropouts, distortion, or persistent weakness even after replacing the wax filter and dome.
How to choose the correct Signia Nx RIC accessories
To make sure you buy the right part, use these quick checks:
Start with what you’re replacing: If possible, match the same dome style/size and the same wax filter system currently used.
Check the receiver end: The receiver tip determines which wax filter fits.
Look for markings: Receivers are commonly marked for side (L/R), length, and power level.
If comfort or sound changed: Consider whether you need a different dome type (open vs closed vs power) rather than just a new dome in the same style.
Common Signia Nx RIC problems (and the accessory that usually fixes them)
Muffled or weak sound: Replace the wax filter; then check the dome and receiver opening.
Whistling (feedback): Try a better-sealing dome (closed/power) or a slightly larger size; also check for a loose fit.
Dome keeps slipping off: Confirm the correct dome size and that it’s fully attached to the receiver.
Sound cuts in/out: Check wax filter first; if it persists, the receiver/wire may be failing.
Irritation or soreness: Try a different dome size or style; make sure the dome is clean and replaced regularly.

FAQ: Signia Nx RIC series accessories
How often should I replace domes on Signia Nx RIC hearing aids?
Many users replace domes regularly for hygiene and fit. If the dome becomes loose, stiff, discoloured, or uncomfortable, it’s time to replace it.
How do I know if my wax filter is clogged?
Typical signs are muffled sound or reduced volume. If changing the wax filter restores sound immediately, the old filter was clogged.
Are all Signia wax filters compatible with the Nx RIC series?
No. Wax filters depend on the receiver design and the filter system used. Always choose the wax filter type that matches your receiver end.
Do I need a left and right receiver?
Yes—receivers are side-specific (left/right) and must also match the correct length and power level used in your fitting.
What if I’m between two dome sizes?
If the smaller size feels loose or whistles, the larger size often improves seal and retention. Comfort matters—if either size causes soreness, consider a different dome style.
