Phonak Naída B-UP BTE Accessories & Compatibility Guide | Japebo
If you use a Phonak Naída B-UP BTE hearing aid, choosing the correct accessories is mainly about matching the exact sound delivery setup (earhook + tubing to an earmold, or other coupling used by your hearing care professional). This guide explains which accessory types are typically used with the Phonak Naída B-UP BTE, how to identify what you have, and how to avoid buying parts that won’t fit.
What type of hearing aid is the Phonak Naída B-UP BTE?
The Phonak Naída B-UP BTE is a behind-the-ear (BTE) model. In most fittings, the sound leaves the hearing aid through an earhook, continues through tubing, and reaches your ear via an earmold (or a custom earpiece). Because of this, many users of the Naída B-UP BTE do not use “domes” in the same way that RIC (receiver-in-canal) hearing aids do.
Accessories most commonly used with Phonak Naída B-UP BTE
Depending on your individual fitting, the accessories you’ll most often need fall into these categories:
Tubing (and tubing-related parts)
If your Naída B-UP BTE uses an earmold setup, the tubing is the part that most often needs replacement over time. Tubing can harden, discolor, or become less flexible, which may affect comfort and sound. The exact tubing type varies (diameter and wall thickness), and it must match your earmold and earhook.
How to choose: identify whether your tubing is standard/thick or thin, and whether it is a continuous tube or uses specific connectors. If you are unsure, compare to your current tube or check with your hearing clinic before ordering.
Earhooks (tone hooks)
The earhook attaches to the hearing aid and guides sound into the tubing. Earhooks can differ by shape, size, and acoustic properties. If your earhook looks cracked, loose, or clogged with debris, replacing it can restore sound quality.
Tip: make sure you select an earhook intended for Phonak Naída B BTE styles, as earhook designs can differ across families and generations.
Earmolds and earmold upkeep
Earmolds are typically made individually for your ear, so they are not usually “standard accessories” that you can select generically. However, routine upkeep matters: keeping the sound pathway clear and replacing worn tubing helps maintain performance.
Cleaning and maintenance items
BTE fittings with tubing/earmolds benefit from simple maintenance tools to reduce moisture and blockages. If you often experience reduced sound, intermittent performance, or muffling, cleaning and drying routines are often the fastest fix.
Compatibility: how to confirm what fits your Naída B-UP BTE
For the Phonak Naída B-UP BTE, “compatibility” usually means matching three things:
Your coupling type: earmold with tubing (most common) versus any alternative setup your provider fitted.
Your earhook type: the exact hook model and size used on your device.
Your tubing specification: diameter/thickness and connector style.
The safest way to confirm is to use your current parts as the reference (visual match + measurements if available). If your current tubing or earhook is missing, your hearing clinic can often identify the correct specification quickly.
Common problems (and the accessory-related fixes)
The sound is weak or muffled
Check for moisture or debris in the earhook or tubing.
Replace tubing if it has hardened, kinked, or discolored.
Inspect the earhook for blockage or damage.
Whistling (feedback) is getting worse
Check that your earmold is seated properly.
Replace old tubing—loose or hardened tubing can worsen feedback.
If it continues, it may indicate a fit change and you may need an earmold adjustment.
The tubing keeps slipping off
This often means the tubing size/type doesn’t match the earhook or earmold connector anymore (or the tube is worn).
Replacing the tubing with the correct specification typically resolves it.
Buying Phonak Naída B-UP BTE accessories online (what to check first)
Before you buy, confirm these details to avoid returns and downtime:
Look at your current setup: note the earhook shape and how the tube attaches.
Decide what you’re replacing: tubing only, earhook, or both.
Match the exact type: especially for tubing diameter and connectors.
If you want the quickest success rate, replace like-for-like by matching the part you already use on your Phonak Naída B-UP BTE.
FAQ: Phonak Naída B-UP BTE accessories
Does the Phonak Naída B-UP BTE use domes?
Most Naída B-UP BTE fittings use an earhook + tubing + earmold rather than standard RIC-style domes. If you are wearing domes, your setup may be different—confirm the coupling type before purchasing dome-style accessories.
What should I replace most often?
Tubing is one of the most commonly replaced items in BTE earmold fittings because it can harden, discolor, and affect comfort and sound quality over time.
How do I know which tubing I need?
The correct tubing depends on the earmold connector and the earhook. The best method is to match the tubing you currently have (same thickness/diameter and same connection style). If unsure, ask your hearing care professional for the tubing specification.
Will accessories for other Phonak Naída models fit the Naída B-UP BTE?
Sometimes—but not always. Even within the Naída line, accessories like earhooks and tubing interfaces can vary by generation and fitting style. For best results, choose parts explicitly intended for Phonak Naída B BTE fittings or match your existing part exactly.
Can I fix muffled sound without buying anything?
Often, yes. First check for blockages or moisture in the tubing/earhook and perform a careful cleaning/drying routine. If muffling returns frequently, replacing tubing (and sometimes the earhook) is usually the next step.
