Signia CROS Pure 312 X RIC accessories & compatibility guide | Japebo
If you’re looking for Signia CROS Pure 312 X RIC accessories, the most important thing is compatibility: the correct dome shape, the right receiver type (if relevant to your setup), and the matching wax protection system. This guide helps you identify what fits your Signia CROS Pure 312 X RIC so you can order with confidence and avoid returns.
What is the Signia CROS Pure 312 X RIC?
The Signia CROS Pure 312 X RIC is a CROS transmitter in a RIC (Receiver-in-Canal) style. In a CROS setup, the CROS device transmits sound from the non-hearing side to a compatible hearing aid on the better-hearing ear. Because CROS solutions can be paired with different hearing aid configurations, accessory compatibility can depend on the exact hardware combination you use (CROS unit + the receiving hearing aid).
In practice, the accessories you replace most often are the parts that sit in or near the ear canal (like domes and wax protection) and comfort/retention parts. The correct match ensures comfort, stable sound, and fewer dropouts or feedback issues.
How to check compatibility for Signia CROS Pure 312 X RIC accessories
To choose the right part, start by identifying:
Your exact model name: Signia CROS Pure 312 X RIC (and, if possible, the paired hearing aid model).
The ear-piece style: dome (open/closed/power) or custom earmold.
The connection system: what sits between the wire and the ear (receiver/dome interface) and which wax protection is used.
If you still have the original packaging or your clinician’s fitting sheet, it often lists dome size/type and receiver details. If not, you can usually identify parts visually by comparing them to product photos and checking the attachment style.
Domes for Signia CROS Pure 312 X RIC: types and how to choose
Domes are the soft silicone tips that sit in the ear canal. They affect comfort, retention, sound balance, and feedback control. The right dome depends on your ear canal and the sound strategy chosen for your fitting.
Common dome styles (what they’re for)
Open domes: More ventilation and a natural feel. Often preferred when you want less “plugged” sensation.
Closed domes: More sealing than open domes, which can help with feedback control and sound stability.
Power domes: Maximum sealing. Typically used when more isolation is needed.
Choosing the right dome size
Dome sizes are generally chosen by comfort and stability. If the dome feels loose or whistles (feedback), you may need a larger size or a more closed style. If it feels tight or causes soreness, you may need a smaller size or a more open style.
Tip: When changing dome type (not just size), the sound and comfort can change noticeably. If your hearing professional recommended a specific style, it’s best to stick with it unless you’re troubleshooting an issue.
Receivers, wires, and ear-side parts: what applies to a CROS RIC setup
With RIC devices, the sound is typically delivered via a receiver/wire assembly on the hearing aid side. In a CROS system, the CROS unit itself transmits, and the receiving hearing aid delivers the sound to the ear. That’s why it’s important to distinguish between:
Accessories for the CROS unit (comfort/retention parts, microphone port care, battery-related items), and
Accessories for the paired hearing aid (receiver, dome, wax filter).
If you are shopping for a receiver, you will usually need the receiver that matches the paired Signia hearing aid (the device on the better ear), not the CROS transmitter itself. If you’re unsure, match by model family and connection style, or check the receiver label/markings on your current part.
Wax protection (wax filters) for Signia: why the exact type matters
Wax filters protect the sound outlet/receiver opening from earwax and moisture. Using the wrong filter can lead to poor sound, intermittent audio, or a loose fit.
To choose the correct wax filter, identify the wax protection system used in your ear-piece/receiver. The easiest way is to compare your current filter to product photos and check how it mounts (press-in, click-in, tool-based removal, etc.).
Common problems with Signia CROS Pure 312 X RIC accessories (and quick fixes)
1) Whistling / feedback
Often caused by a dome that’s too small or too open, or by a dome that’s not seated properly. Try reseating the dome, then consider a larger size or a more closed style if the problem persists.
2) Sound seems weak or muffled
Most commonly wax blockage. Replace the wax filter (and dome), and check for moisture or debris around the sound outlet.
3) Dome falls off or stays in the ear
This can happen when domes are worn out or the wrong type is used. Replace the dome more often and ensure it is firmly attached. If this happens repeatedly, consider a different dome style or retention solution.
4) Irritation or soreness
Usually a size/style issue or a worn dome edge. Try a different size, switch to a more ventilated design, and replace domes regularly.
When should you replace domes and wax filters?
As a rule of thumb:
Domes: replace when they feel loose, look discolored, or no longer hold shape (often every few weeks depending on use).
Wax filters: replace whenever sound drops, becomes muffled, or you see visible blockage.
Regular replacement helps maintain stable sound and reduces troubleshooting.

FAQ: Signia CROS Pure 312 X RIC accessories
Are Signia CROS accessories the same as regular Signia RIC accessories?
Some are shared (comfort parts, general maintenance items), but ear-side parts like receivers, domes, and wax filters typically depend on the paired hearing aid and the specific ear-piece system used.
How do I know which dome fits my Signia CROS Pure 312 X RIC setup?
Match the dome style and size you currently use, or identify the recommended type from your fitting. If you’re troubleshooting feedback or comfort, adjust size/style step-by-step rather than changing multiple variables at once.
Can the wrong wax filter reduce sound?
Yes. A mismatched wax filter may not seal or protect correctly, leading to muffled sound or intermittent output. Always use the filter type designed for your receiver/ear-piece system.
What if I don’t know my paired hearing aid model?
Check the name printed in the hearing aid app, in your original documentation, or on the device itself. The receiving hearing aid model determines many ear-side parts (especially receivers and wax filters).
