Signia Charismo RIC – Guides & Compatible Accessories | Japebo
If you’re looking for Signia Charismo RIC accessories, you’re in the right place. Charismo RIC hearing aids use small, replaceable parts that affect comfort, sound quality and reliability—most commonly domes (ear tips), receivers/speakers and wax protection. This guide explains what fits Signia Charismo RIC, how to identify the correct option, and what to do if you’re unsure before you buy.
What “RIC” means on Signia Charismo RIC
RIC stands for Receiver-in-Canal. Instead of having the speaker inside the hearing aid housing, the speaker (receiver) sits in the ear canal and is connected by a thin wire. On Signia Charismo RIC models, this means:
The receiver is a wear part and can be replaced if it becomes weak, intermittent or stops working.
You’ll typically use soft domes (open/closed/power styles) attached to the receiver for comfort and sound sealing.
Wax protection is essential—earwax is one of the main causes of reduced volume and receiver failure.
Which accessories are typically used with Signia Charismo RIC
Most users will be choosing between these accessory types for their Signia Charismo RIC hearing aids:
Domes (ear tips)
Domes determine how the receiver sits in the ear and how much sound is vented. Common dome styles include:
Open domes – More natural sound and ventilation; often used for mild to moderate hearing loss.
Closed domes – More sealing and stronger low-frequency amplification; helpful when you need more “hold” in the ear or less whistling.
Power domes – Maximum seal and retention; often used for greater hearing loss or when feedback must be controlled.
If your hearing aid starts to whistle, feels loose, or sounds thinner than usual, the dome size or style may be the issue (or the dome may simply be worn and need replacing).
Receivers (speakers)
The receiver is the speaker at the end of the wire. You need the correct receiver type and usually the correct length (left/right and wire length). A receiver that doesn’t match can cause poor fit, discomfort, or connection issues.
Typical signs you may need a new receiver:
Sound is weak, distorted, crackling or cuts in/out
One side is noticeably quieter than the other
Cleaning and replacing wax protection doesn’t restore sound
Wax filters / wax protection
Wax protection prevents earwax and moisture from entering the receiver. If your Signia Charismo RIC suddenly becomes quieter, the first and easiest fix is often replacing the wax filter (and checking that the dome is clean and fully attached).
How to choose the correct Signia Charismo RIC parts
To choose compatible accessories for Signia Charismo RIC, focus on identification first—then ordering. The most reliable approach is to match what you already use.
1) Check what’s currently on your hearing aid
Domes: note the style (open/closed/power) and size (diameter). If you still have the packaging, match the part number.
Receiver: look for markings on the wire/receiver (often includes side and length). If in doubt, compare left vs right.
Wax protection: compare the shape and mounting style to your current filter/tool.
2) Match the side and length for receivers
Receivers are side-specific (left/right) and come in different lengths. Using the wrong length can pull the hearing aid off the ear or leave the receiver sitting incorrectly in the canal.
3) Choose dome style based on sound and fit
If you’re unsure which dome type to choose for Signia Charismo RIC, use these practical rules:
Prefer a more open dome if your ear feels blocked or your own voice sounds too loud/boomy.
Prefer a more closed dome if you need more bass/fullness, the fit is loose, or you get feedback (whistling).
Replace domes regularly—when they harden, they seal poorly and can slip off.

FAQ: Signia Charismo RIC accessories
How often should I replace domes on Signia Charismo RIC?
Most users replace domes regularly because they wear, harden and lose grip. If the dome feels loose, uncomfortable, or changes the sound, replace it sooner.
Do all Signia RIC receivers fit Signia Charismo RIC?
Not necessarily. Signia has used multiple receiver platforms over time. The safest method is to match the receiver type and markings from your current receiver (including side and length) rather than assuming all Signia RIC receivers are interchangeable.
My hearing aid is quiet—should I replace the receiver or the wax filter?
Start with the wax filter, as it’s a common cause of sudden reduced volume and is quick to replace. If changing the wax filter doesn’t help, the receiver may be damaged or blocked internally.
What’s the difference between open and closed domes?
Open domes let more natural sound and air through, while closed domes seal more to provide stronger amplification (especially for low frequencies) and can reduce feedback.
How do I know the correct receiver length?
Receiver length is usually printed on the receiver/wire and differs between left and right. If you can’t find markings, compare the fit: the correct length allows the hearing aid to sit securely behind the ear while the receiver rests comfortably in the canal without pulling.
