Phonak Naida B RIC accessories & compatibility guide | Japebo
If you use Phonak Naida B RIC hearing aids, the most important step when buying parts is confirming compatibility. Small accessories like domes, receivers and wax filters can look similar across Phonak models, but they are not always interchangeable. This guide explains what typically fits the Phonak Naida B RIC, how to identify the correct option, and how to avoid the most common ordering mistakes.
What “Naida B RIC” means for accessories
Naida B refers to the Phonak Naida family built on the Belong platform. RIC (Receiver-In-Canal) means the speaker (receiver) sits in the ear canal and connects to the hearing aid via a thin wire. Because of this design, the accessories you replace most often are:
Receivers (speaker units/wires)
Domes (ear tips)
Wax filters / wax guards (when used with a receiver style that supports filters)
Retention pieces / sports locks (if your fitting uses them)
Compatibility checklist (use this before you buy)
To make sure you are choosing the right Phonak Naida B RIC accessory, match these details from your current setup:
1) Confirm it’s Naida B RIC (not a different Naida version)
Check your fitting paperwork, the model name in the myPhonak app (if used), or ask your hearing care professional. “Naida” models exist in multiple platforms/generations and can use different parts.
2) Identify your receiver type and size
Receivers come in different power levels (e.g., standard vs power) and different wire lengths. The receiver type determines which domes and wax protection system you need.
3) Match the dome connection system
Phonak domes must match the exact receiver/dome coupling system used on your Naida B RIC fitting. If the dome does not “click” or sit securely, it is usually the wrong system (even if the size looks right).
4) Check which wax protection you use
Phonak has used multiple wax filter styles. The correct choice depends on the receiver and its ear-tip design. If you’re unsure, compare the filter shape and how it sits in the receiver (or use your current filter packaging as reference).
Phonak Naida B RIC receivers: how to choose the right one
When replacing a receiver for a Phonak Naida B RIC, you typically need to match:
Left vs right (often marked with blue/red)
Length (commonly printed on the receiver/wire)
Power level (your fitter selected this based on your hearing loss)
Connector/generation (must match your hearing aid and the receiver family used in your fitting)
If your current receiver works but sound is weak or intermittent, it may be blocked by wax/moisture rather than “wrong.” Try cleaning and replacing wax protection first.
Domes for Phonak Naida B RIC: types and who they’re for
Domes affect comfort, feedback (whistling), and sound (especially bass). With Phonak Naida B RIC fittings, the most common dome styles are:
Open domes
Best when you want a more “open” feeling and natural low-frequency hearing. They can be more prone to feedback if you need a lot of amplification.
Closed domes
Provide a tighter seal than open domes. Often used when you need more support in the low-to-mid frequencies or to reduce feedback.
Power domes
Designed for a stronger seal and typically used with higher power needs. They can improve bass and reduce feedback, but may feel more occluding.
Tip: If you changed domes recently and suddenly get feedback or muffled sound, the dome type or size is usually the cause. Returning to your previous dome type/size is a quick way to confirm.
Wax filters / wax guards: what to look for
Wax protection prevents earwax from entering the receiver and causing damage or sound dropouts. For Phonak Naida B RIC fittings, the correct wax filter depends on the receiver/ear-tip system used. Choose based on:
Exact filter model you already use (best indicator)
How it installs (press-in, tool-based, integrated holder, etc.)
Receiver style (some receiver types use different protection)
Replace wax filters when sound becomes weak, dull, or intermittent, or after heavy wax exposure. If your receiver does not use separate filters, you may instead need to clean/replace the ear tip components recommended for your receiver type.
Common problems (and the accessory that usually fixes them)
Sound is weak or muffled
Most often: blocked wax filter, blocked dome, or moisture in the receiver. Start by changing the wax filter (if applicable) and dome, then check the receiver.
Whistling / feedback
Most often: dome too small, dome not fully attached, or dome type too open for your fitting. Try the correct size or a more closed/power dome as advised by your hearing care professional.
Dome keeps falling off
Most often: wrong dome coupling system or worn dome. Replace with the correct dome series for your receiver and avoid mixing look-alike domes from other Phonak families.
Intermittent sound (cuts in and out)
Most often: receiver cable damage or moisture. If new filters/dom es don’t help, the receiver may need replacement.
Buying Phonak Naida B RIC accessories online (how to order confidently)
To order the correct Phonak Naida B RIC parts, use your current accessories as a reference and match:
Receiver length and power level
Dome series (connection system), type (open/closed/power) and size
Wax filter model (same as you currently install)
If you are unsure, it is safer to identify your existing receiver and dome system first than to “guess” based on appearance. Correct matching reduces feedback, improves comfort, and prevents returns.
FAQ: Phonak Naida B RIC accessories
Are Phonak Naida B RIC accessories the same as other Phonak RIC models?
Not always. Some accessories may look similar across Phonak families, but receivers, dome systems and wax guards can differ by platform/generation and receiver type. Always match the accessory to your exact Naida B RIC setup.
How do I find my receiver length and power level?
It is often printed on the receiver/wire or can be found in your fitting documentation. If you can’t locate it, your hearing care professional can confirm the correct specifications.
How often should I change domes and wax filters?
Wax filters are replaced when blocked (often every few weeks to months, depending on wax). Domes are typically replaced when they feel loose, discolored, stiff, or no longer fit comfortably (commonly monthly or as needed).
What if I order the wrong dome size?
If the size is wrong, you may notice discomfort, poor retention, feedback, or reduced sound quality. Choose the size that matches your current dome, and consider buying multiple sizes only if you are actively fine-tuning the fit.
Do I need to replace the receiver if sound is weak?
Not necessarily. Start by replacing the wax filter and dome and cleaning the receiver opening. If the problem persists, the receiver may be damaged and need replacement.
