Phonak CORE RIC series | Compatibility guide & accessories (Japebo)
If you’re looking for Phonak CORE RIC series accessories, the most important thing is compatibility: the right part must match your exact RIC setup (receiver style, dome system and wax protection). This guide explains what typically fits the Phonak CORE RIC series and how to choose the correct accessory before you buy.
What is the Phonak CORE RIC series?
The Phonak CORE RIC series refers to Phonak hearing aids built in a RIC (Receiver-In-Canal) style. In a RIC design, the small speaker (receiver) sits in the ear canal and connects to the hearing aid behind the ear via a thin wire. Because the receiver and ear-tip parts are replaceable, many of the most common accessories you’ll buy for a CORE RIC model are:
Receivers (the speaker/wire assemblies)
Domes (ear tips that sit on the receiver)
Wax filters/guards (to protect the receiver from earwax and moisture)
Charging-related parts (for rechargeable variants)
Cleaning and care items (to improve hygiene and performance)
How compatibility works for Phonak CORE RIC accessories
Phonak RIC compatibility is usually determined by a few practical factors. Before choosing an accessory, identify:
Receiver platform (the specific receiver type used by your CORE RIC model)
Receiver power level (e.g., standard vs power—varies by configuration)
Dome connection system (the dome style that clicks onto your receiver)
Wax protection system (the exact wax filter/guard used in the receiver tip)
If you’re unsure, the quickest checks are: (1) look for the receiver type on your purchase paperwork, and (2) compare your current receiver/dome/wax filter visually to the replacement option. If you can share your current receiver type or a photo, compatibility can usually be confirmed very quickly.
Receivers for Phonak CORE RIC series
The receiver is the most important replaceable part in a RIC setup. If your sound cuts out intermittently, becomes weak, or you experience crackling that doesn’t resolve with a new wax filter, the receiver is often the next thing to check.
How to pick the right receiver
Left vs right: receivers are side-specific.
Length: receiver wires come in different lengths so the hearing aid sits correctly behind the ear.
Power level: your fitting may require a specific receiver strength.
Tip: If your current receiver fits comfortably and routes neatly, match the length and side exactly when ordering.
Domes for Phonak CORE RIC series
Domes are the soft silicone ear tips that attach to the receiver. They influence comfort, retention in the ear, sound quality, and how much outside sound mixes naturally with amplified sound.
Common dome types (and what they’re for)
Open domes: more natural feel and ventilation; often used for mild to moderate fittings.
Closed domes: more sealing than open; can add bass and reduce feedback.
Power domes: strongest seal; often used when more amplification is needed.
How to choose the right dome
Match the connection: Phonak receivers use specific dome styles—choose the dome system designed for your receiver platform.
Choose the size for comfort and seal: too small can whistle (feedback) or fall off; too large can be uncomfortable.
Replace regularly: domes can harden over time and affect comfort and sound.
Wax filters/guards for Phonak CORE RIC series
Wax protection is essential for RIC receivers because the receiver sits in the ear canal. A blocked wax filter is one of the most common causes of muffled sound or “no sound” on one side.
How to select the correct wax filter
Use the same system as your current receiver: wax filters are not universal.
Check the receiver tip design: the opening and filter seat must match.
Replace at the first sign of blockage: if sound returns after changing the filter, you’ve found the issue.
Charging and power accessories (for rechargeable CORE RIC variants)
If your Phonak CORE RIC model is rechargeable, keeping the charging setup reliable matters as much as the ea
