Phonak Naída I BTE hearing aid accessories & compatibility guide | Japebo
If you use a Phonak Naída I BTE hearing aid, choosing the right accessory is mainly about matching the exact fitting system on your device (hooks/tubing, earmould setup, and battery size), rather than guessing based on looks. This guide explains what typically fits Phonak Naída I BTE models, how to identify what you need, and how to avoid the most common compatibility mistakes before you buy.
What kind of hearing aid is the Phonak Naída I BTE?
Naída I BTE is a behind-the-ear (BTE) hearing aid family designed for robust performance and higher power needs. BTE devices usually connect to your ear via either:
An earhook + tube (leading to an earmould), or
A thin tube (leading to a small dome or slim-tip style earpiece), depending on configuration.
Because Naída I BTE setups can vary, the safest way to buy accessories is to identify the parts currently on your hearing aid and replace like-for-like (or upgrade intentionally with the right size).
Phonak Naída I BTE accessories you can typically replace
The most common consumables and replaceable parts for BTE hearing aids include:
Batteries (size depends on your exact Naída I BTE variant)
Earhooks (the plastic hook on top of the hearing aid)
Tubing (standard tube to an earmould, or thin tube if your fitting uses one)
Cleaning and care products (wipes, sprays, drying solutions)
Earmould-related parts (if applicable, typically provided/adjusted by a clinic)
Some accessories (like domes and wax filters) are common on receiver-in-canal (RIC) devices, but many classic BTE earmould setups don’t use those items in the same way. If you’re unsure which style you have, use the quick checks below.
How to check which parts your Phonak Naída I BTE uses (quick compatibility checks)
1) Look at how sound goes into your ear
Earmould setup: You have a custom mould in your ear connected by a thicker clear tube. You’ll typically need standard tubing and possibly an earhook.
Thin tube/dome setup: You have a very thin tube and usually a small silicone dome in the ear. You’ll need the correct thin tube type/length and the correct dome style/size (if used).
2) Identify your battery size
Open the battery door and check the battery size (often color-coded by standard):
10 (yellow)
312 (brown)
13 (orange)
675 (blue)
Important: Different Naída I BTE variants can use different battery sizes. Match the number printed on your current battery/pack.
3) Check whether the earhook is removable
Many BTE earhooks can be replaced when they discolor, crack, or no longer hold tubing securely. If you see a distinct hook piece on top of the hearing aid where the tube attaches, you likely have a replaceable earhook.
Choosing the right replacement: what matters most
To choose correctly for Phonak Naída I BTE, focus on these points:
Same coupling type: earmould + standard tube vs thin tube + dome
Correct tube diameter/length: match what you currently wear (or measure/compare)
Correct battery size: match the printed size
Left/right (if thin tubes are used): many thin tube systems are side-specific
If you can, compare your current part to the product photos and specifications before ordering. When in doubt, replacing with the same type/size as your existing part is the lowest-risk option.
Common Phonak Naída I BTE issues & simple fixes
Whistling/feedback
Check if the tube is loose, stiff, or cracked
Make sure the earmould/dome is inserted fully
Consider whether the fit has changed (weight loss, earmould wear)—an earmould may need refitting
Sound is weak or intermittent
Replace the battery first
Inspect the tube for moisture or blockage
Clean the earmould opening and tube (or replace tubing if it has hardened)
Tubing keeps falling off the hook
Replace the earhook if it’s worn or smooth
Ensure you use the correct tube size for the hook

FAQ: Phonak Naída I BTE accessories & compatibility
Are all Phonak BTE accessories compatible with Naída I BTE?
No. Compatibility depends on the specific coupling system (earhook/tubing type) and the exact hearing aid variant. Always match what is currently on your device or confirm by model details.
Do I need domes and wax filters for a Phonak Naída I BTE?
Many Naída I BTE users with earmould + standard tube do not use domes in the same way as RIC devices. Wax protection is often built into the earmould sound outlet rather than a separate wax filter system. If you have a thin tube + dome fitting, then domes may apply.
How often should I replace the tubing?
Replace tubing when it becomes stiff, yellowed, cracked, or if you notice more feedback or reduced sound. Frequency varies, but many users replace it every few months depending on wear and moisture.
How do I know which battery my Naída I BTE uses?
Check the number on your current battery pack (10/312/13/675) or the battery itself. Buy the same size to ensure proper fit and runtime.
What if I still can’t identify the right accessory?
Use your current part as a reference and look for any markings on the tube/hook packaging, or check your hearing aid paperwork. If you can share the exact model name/serial family and a photo of the coupling (hook/tube), it becomes much easier to identify the correct match.
