Widex Magnify BTE 312 – Accessories & Compatibility Guide | Japebo
If you’re looking for the correct Widex Magnify BTE 312 accessories, you’re in the right place. This guide explains what typically fits the Magnify BTE 312 setup and how to choose the right replacement parts—so you can order confidently and avoid compatibility mistakes.
What kind of hearing aid is Widex Magnify BTE 312?
The Widex Magnify BTE 312 is a behind-the-ear model that uses a size 312 battery and commonly connects to either:
a thin tube with a small ear dome (open/vented/power), or
a custom earmould (which may also attach via tubing).
Because accessories depend on the exact fitting configuration (tube, earmould, receiver/hook type), the safest approach is to identify how your Magnify BTE 312 is built before you buy replacements.
How compatibility works for Widex Magnify BTE 312 accessories
Widex accessories are not universally interchangeable across all Widex models. For the Magnify BTE 312, compatibility is decided by a few practical checkpoints:
Battery size: this model uses 312 (brown tab) batteries.
Sound delivery: thin tube + dome vs. earmould (different parts are required).
Tube/hook style: different hooks/tubes accept different dome systems.
Wax protection: wax guards (if used) must match the exact ear-piece system.
If you’re unsure, compare your current parts to the product photos/specs or use the identifiers below.
Most common accessory types for Widex Magnify BTE 312
312 batteries (power supply)
Widex Magnify BTE 312 uses size 312 batteries. If your current batteries have a brown sticker/tab, you’re using the correct type. When replacing, choose high-quality zinc-air 312 batteries for stable performance.
Domes (the soft tip in the ear)
If your Magnify BTE 312 is fitted with a thin tube and dome, you’ll need domes that match the tube’s dome-attachment system. Domes generally come in three common styles:
Open domes: airy feel, more natural sound, often used for mild to moderate losses.
Vented/closed domes: more sealing than open, helps with feedback control.
Power domes: most sealing, used when more amplification is needed.
Tip: If your dome feels loose, whistles (feedback), or slips off the tube, it’s often the wrong size or the wrong attachment type—not just “worn out”.
Thin tubes / tubing
Many BTE 312 fittings use a replaceable thin tube (often available in different lengths and left/right versions). A worn tube can cause poor sound, discomfort, or domes not sitting correctly.
To pick the right tube, you usually need:
Length code (often printed on the tube or packaging), and
side: left vs. right.
Earmould tubing (if you use a custom mould)
If you wear a custom earmould, you may have standard earmould tubing instead of (or in addition to) a thin tube. In that case, the key is matching the correct tubing diameter and ensuring the tubing sits securely on the hook and mould.
Wax guards / wax protection (only if your earpiece uses them)
Wax protection depends heavily on the end piece you have (dome system vs. mould system). Some BTE thin-tube dome setups rely on built-in protection, while others use replaceable wax guards.
If your current earpiece has a removable wax filter, replace it with the same Widex wax guard type. Using the wrong filter can block sound or fail to protect the device.
How to choose the right Widex Magnify BTE 312 replacement parts
Use these steps to avoid ordering incompatible accessories:
Confirm your model: Widex Magnify BTE 312.
Check your current setup: dome + thin tube, or custom earmould.
Match the attachment: domes must fit your specific tube/hook system.
Match the size: dome diameter and tube length must match your current parts.
Replace like-for-like first: if you’re happy with the sound/comfort, reorder the same style and size.
If you want to change dome style (for example from open to more closed), it can affect comfort, occlusion, and feedback. If in doubt, choose the same type you already use or ask your hearing care professional.
Common problems (and the accessory that usually fixes them)
Whistling / feedback: dome too small, dome not seated, or you need a more closed dome style.
Sound is weak or muffled: blocked wax protection, moisture in tube, or tube needs replacing.
Dome falls off: wrong dome attachment type or worn dome/tube connection.
Discomfort / pressure: dome too large or dome style too closed for your ear.
Short battery life: old batteries, poor storage, or battery door not closing cleanly due to debris.
