Phonak Audéo I CROS accessories & compatibility guide | Japebo
If you use Phonak Audéo I CROS, choosing the right accessories is mostly about one thing: compatibility. Small parts like domes, wax filters, and receivers must match your specific fitting and speaker type—otherwise comfort, sound quality, and retention can suffer. This guide explains which accessories typically fit Phonak Audéo I CROS, how to identify what you need, and what to do if something doesn’t feel or sound right.
What is Phonak Audéo I CROS (and why accessory choice matters)?
Phonak Audéo I CROS is a CROS hearing solution designed for single-sided hearing (one ear has unaidable hearing). Even though the system functions differently than a standard hearing aid, the parts that sit in or on your better-hearing ear still depend on the physical fit of the device: the speaker/receiver style, how the sound is delivered into the ear canal, and how the device is protected from earwax and moisture.
Because several Phonak families use similar-looking components, it’s important to select accessories that match your exact setup rather than relying on appearance alone.
Accessory types commonly used with Phonak Audéo I CROS
The most common accessory categories for Phonak Audéo I CROS users are:
Domes (ear tips): determine comfort, retention, and how “open” or “sealed” the fit is.
Wax filters / wax guards: protect the receiver opening from earwax buildup.
Receivers (speakers): the part that delivers sound into the ear; must match power level and connection type.
Retention locks: small stabilizers that help keep the receiver and dome in place.
Cleaning & care: cleaning tools, drying solutions, and accessories that help prevent blockage and moisture issues.
How to confirm compatibility for your Phonak Audéo I CROS
To choose the correct Phonak Audéo I CROS accessories, check these three points first:
1) Your receiver and coupling type
Many Phonak Audéo instruments use a receiver-in-canal (RIC) setup, where the receiver sits in the ear canal and connects via a thin wire. Domes, wax filters, and retention locks must match the exact receiver type you have.
2) The size and style of your dome
Domes come in different sizes and shapes (for example: open, closed, or power-style). The right choice depends on comfort, feedback (whistling), and how much outside sound you want to let in naturally.
3) Your wax filter system
Phonak uses different wax protection systems across models and generations. The best way to confirm the correct wax filter is to match the type you currently use (shape/colour/holder style) or check your hearing care provider’s documentation.
How to choose the right parts (simple decision help)
Choosing domes for Phonak Audéo I CROS
Use these guidelines:
Open domes: often chosen for comfort and a natural sound, especially if you have good low-frequency hearing in the better ear.
More closed domes: can help if you experience feedback (whistling) or want more focus/volume, but may feel more occluding.
Go by fit first: if a dome feels loose, sound may be thin and it may fall off; if it’s too tight, it can cause soreness.
Choosing wax filters
If sound becomes weaker or dull over time, a blocked wax filter is one of the most common causes. Choose the exact same wax filter type as your current one. If you’re unsure, identify it by comparing the filter tool and the filter shape—or contact support with a photo of your receiver tip.
Choosing receivers
Receivers must match both:
Connection type (the interface to your device)
Power level (often indicated by markings such as S/M/P or similar)
If you’re replacing a receiver, match the exact markings on your existing receiver wire (and the left/right side). When in doubt, choose based on the receiver code printed on the part you already use.
Common problems (and the most likely accessory fix)
“The sound is weak or muffled”
Most often: wax filter is blocked → replace it.
Also possible: moisture or debris in the dome → clean or replace the dome.
“It whistles (feedback)”
Dome is too small or not sealing well → try the next size up or a more closed style.
Receiver may not sit properly → check retention lock and insertion depth.
“It feels itchy or sore”
Dome may be too large or the style doesn’t suit your ear canal → try a smaller size or a different dome type.
Replace domes regularly—old domes can harden and irritate skin.
“The dome falls off”
Wrong dome size or worn dome material → replace with a fresh dome and verify the correct fit.
Check that the dome is fully seated on the receiver tip.

FAQ: Phonak Audéo I CROS accessories
Are Phonak Audéo accessories always compatible with Audéo I CROS?
Not always. Compatibility depends on the specific receiver and wax filter system used with your device. Always match the accessory to your exact receiver type and current consumables.
How often should I change domes and wax filters?
Wax filters should be changed whenever sound becomes weaker/muffled or you see wax buildup. Domes should be replaced regularly for hygiene and comfort (many users replace them every few weeks, depending on earwax and wear).
Can I use any Phonak wax filter if it “looks similar”?
No. Different wax filter systems may look alike but fit differently. Using the wrong one can lead to poor protection, blockage, or improper seating.
What if I don’t know which receiver I have?
Check the printing/markings on the receiver wire (often includes side and power code). If you can’t find it, compare your current receiver tip and connection type, or use a clear photo to confirm the correct match before buying.
Do I need special cleaning products for Phonak Audéo I CROS?
You don’t need anything complicated, but basic cleaning tools and regular care help prevent blockage and moisture issues. The most important “maintenance accessory” is often simply having the correct wax filters and spare domes available.
