Signia Pure 13 Nx RIC Accessories & Compatibility Guide | Japebo
If you use Signia Pure 13 Nx RIC hearing aids, choosing the right accessories matters for comfort, sound quality, and reliable day-to-day use. This guide explains which Signia Pure 13 Nx RIC accessories are typically compatible, how to identify what you need (before you buy), and how to fix common issues like feedback, weak sound, or poor retention.
What “RIC” means for Signia Pure 13 Nx compatibility
Signia Pure 13 Nx is a RIC (Receiver-in-Canal) model. That usually means you have:
a hearing aid that sits behind the ear,
a thin receiver wire going into the ear canal, and
either a dome (silicone tip) or a custom earmold on the end of the receiver.
Because of this design, compatibility is mainly determined by the receiver type/length, the dome connection system, and the wax protection system used at the receiver end.
Accessories that most commonly fit Signia Pure 13 Nx RIC
These are the accessory categories most Signia Pure 13 Nx RIC users replace regularly:
Domes (ear tips)
Domes affect both comfort and sound. A more open dome feels lighter and can reduce “plugged ear” feeling, while a more closed dome can increase bass and improve audibility in noise. The correct dome must match the receiver’s dome mounting style used on your Pure 13 Nx.
Wax filters / wax guards
Wax protection prevents earwax and moisture from blocking the receiver opening. If sound becomes weak or intermittent, the wax guard is often the first thing to replace. Compatibility depends on the wax system built into your receiver or mold.
Receivers (speaker units) and receiver wires
Receivers are not universal across brands or even across all Signia families. To choose the right one you typically need:
receiver power level (e.g., S/M/P depending on your fitting),
wire length (often numbered), and
left vs. right.
If you are unsure, check the markings on your current receiver/wire or compare product images and specifications carefully.
Batteries (size 13)
“Pure 13” indicates it uses size 13 hearing aid batteries. If your device uses disposable batteries (not a rechargeable variant), choose high-quality zinc-air size 13 batteries for stable performance.
Cleaning and care items
Cleaning wipes, drying solutions, and small maintenance tools help reduce moisture-related issues and extend receiver life. These are generally universal, but the parts (like wax guards and domes) must be Signia Pure 13 Nx-compatible.
How to choose the correct Signia Pure 13 Nx accessories
If you want to be confident you’re buying the right accessory, use this quick process:
1) Match the accessory to what you have now
The most reliable method is to compare with the accessory currently on your hearing aid:
For domes: note the type (open/closed/power) and size (often in mm).
For wax guards: identify the exact system by shape and dispenser/holder style.
For receivers: read the printing/markings for length, side, and power level.
2) Decide based on your symptom (comfort vs. sound)
If you’re changing accessories because something feels “off,” these are common match-ups:
Feedback/whistling: try a slightly more closed dome or a better-fitting size.
Thin/weak sound: check wax guard first; then consider a more closed dome if appropriate.
Occluded/boomy voice: try a more open dome style if your hearing care professional approves.
Dome falls out: consider a larger size, retention tail (if supported), or alternative dome style.
3) When you should not “guess”
Don’t guess on receivers and wax guard systems if you can’t identify what you currently use. The wrong receiver connection or wax system won’t fit correctly and can lead to poor sound or wasted purchases.
Common problems with Signia Pure 13 Nx RIC (and what usually fixes them)
Sound is weak or cuts in/out
Most often: blocked wax guard, clogged dome, or moisture in the receiver. Replace wax protection, clean/replace domes, and consider drying/storagecare.
Whistling (feedback)
Often caused by a loose dome fit, wrong dome type, or wax blockage changing acoustics. Try a better-fitting dome and replace wax guards.
One ear is much quieter than the other
Swap domes and check wax guards first. If the problem follows the receiver, you may need a receiver replacement.

FAQ: Signia Pure 13 Nx RIC accessories
Which battery does Signia Pure 13 Nx use?
Signia Pure 13 Nx typically uses size 13 zinc-air hearing aid batteries.
Are all Signia domes compatible with Pure 13 Nx?
No. Dome compatibility depends on the receiver and dome mounting system fitted to your Pure 13 Nx. Match the dome style and connection to what you currently use.
How do I know which receiver wire length I need?
Check the markings on your current receiver/wire (often shows length and side) or compare it to product specifications. If you can’t identify it, it’s safer to confirm with your hearing care professional or match the exact receiver model you already have.
How often should I replace wax guards?
It varies with earwax production and humidity, but many users replace wax guards whenever sound becomes weaker, dull, or intermittent—or as part of routine maintenance.
Can wax blockage cause feedback?
Yes. A blocked wax guard or receiver outlet can change acoustics and contribute to feedback and reduced sound quality.
