Phonak Naída M-UP BTE accessories & compatibility guide | Japebo
If you use a Phonak Naída M-UP BTE hearing aid, choosing the right accessories is mostly about one thing: matching the exact connection and acoustic setup (earhook + tubing + earmould, or a slim-tube/open fitting if your device is configured that way). This guide explains which parts typically fit the Phonak Naída M-UP BTE, how to identify what you have today, and how to buy replacements with confidence.
What is the Phonak Naída M-UP BTE?
The Phonak Naída M-UP BTE is a behind-the-ear (BTE) power hearing aid in the Naída Marvel family. BTE models commonly use an earhook and sound tube leading to an earmould, though the exact configuration can vary depending on your fitting. Because multiple BTE setups exist, the safest way to buy accessories is to confirm your current parts (especially the earhook/tubing type) before ordering.
How compatibility works for Phonak Naída M-UP BTE accessories
For Naída M-UP BTE users, compatibility is determined by a few practical checks:
Battery size: your Naída M-UP BTE uses a specific battery size (check the battery door or your current battery packaging).
Hook/tube connection: BTEs typically use an earhook (elbow) on the hearing aid and standard tubing to the earmould. The diameter and style matter.
Earmould vs open fit: if you have an earmould, you’ll usually replace tubing. If you have a slim-tube/open solution, you may instead replace a thin tube and domes (only if your hearing aid has been set up that way).
If you’re unsure, compare your current part visually (shape, locking mechanism, tube thickness) and replace like-for-like.
Accessories and spare parts you may need
Earhooks (BTE hooks / elbows)
The earhook is the small curved connector on the top of the hearing aid where the tube attaches. Replace it if it becomes loose, discoloured, cracked, or if the tube no longer grips properly. When choosing an earhook, make sure the mounting style and tube diameter match what you currently use.
Hearing aid tubing (for earmould fittings)
Most Phonak Naída M-UP BTE fittings use replaceable tubing between the earhook and the earmould. Tubing should be replaced regularly because it hardens over time, which can cause:
whistling/feedback
poorer sound quality
discomfort or a tube that won’t sit properly
To choose the right tubing, match the thickness and type (standard vs thick) to your current tube. If you wear an earmould, the mould typically stays the same while the tube is replaced and trimmed to length.
Domes and thin tubes (only if your Naída M-UP is configured as an open fit)
Some users have a slimmer, more open configuration that uses thin tubes and domes instead of an earmould. If that’s what you have, it’s important to pick the same dome system and size already on your device. Domes generally come in open, closed/vented, and power styles, and the correct choice depends on your hearing loss and feedback control.
If you’re currently using an earmould with standard tubing, domes are typically not the right accessory for your setup.
Wax protection (filters/guards) and earmould cleaning
Wax protection depends on your exact sound outlet configuration. With classic BTE + earmould setups, wax is more commonly managed through regular earmould cleaning and keeping the tube clear rather than using small wax filters in the hearing aid. If your fitting includes a receiver-in-the-canal style component (less common for this model), you may have wax guards—check what is currently installed before buying replacements.
Batteries
The Phonak Naída M-UP BTE is a battery-powered BTE. To buy the correct batteries, confirm the battery size from:
the number/colour on your current battery packaging, or
markings inside/on the battery door.
Using the correct size ensures proper door closure, stable power delivery, and best runtime.
How to choose the correct replacement parts (practical checklist)
Check your current setup: earmould + standard tube, or thin tube + dome.
Match the connection: earhook style and tube thickness/fit must match your current parts.
Replace like-for-like first: if you were happy with comfort and sound, choose the same type again.
When changing style (e.g., different tubing or open fit): consider professional guidance, as it can affect acoustics and feedback.
Common issues and what usually fixes them
Whistling or feedback
Hardened or kinked tubing → replace tubing
Loose earhook or poor tube grip → replace earhook
Earmould not sealing as before → check fit and cleanliness
Sound is weak or muffled
Tube blockage (moisture/earwax) → clean or replace tubing
Battery running low → replace battery
Tube keeps slipping off
Tube has stretched/hardened → replace tubing
Earhook is worn → replace earhook

FAQ – Phonak Naída M-UP BTE accessories
How do I know if I have tubing + earmould or domes?
If you have a custom piece that fills part of your ear (an earmould) with a thicker clear tube, you have tubing + earmould. If you have a thin, flexible tube ending in a small silicone tip, you have an open-fit thin tube + dome setup.
How often should I replace the tubing?
Many users replace tubing when it becomes yellow, stiff, cracked, or starts causing feedback. Frequency varies by earwax and climate, but regular replacement helps maintain sound quality and comfort.
Can I switch to domes on a Naída M-UP BTE?
Sometimes it’s possible, but it depends on your hearing needs and the hardware configuration. Switching from an earmould to an open fit can change acoustics and feedback behaviour, so it’s best done with professional guidance.
What battery does the Phonak Naída M-UP BTE use?
Check the marking on your current batteries or inside the battery door. Once you confirm the size, buy the same size for reliable fit and runtime.
Do I need wax filters for this model?
That depends on your exact sound outlet setup. Classic BTE + earmould fittings usually rely more on keeping the earmould and tube clean than on small wax filters. If you currently have a wax guard system, replace the same type.
