Phonak microSavia Art CRT dSZ accessories & compatibility guide | Japebo
If you use a Phonak microSavia Art CRT dSZ hearing aid, choosing the correct accessory is mainly about matching the exact speaker/receiver setup and the connecting parts that sit in (or close to) your ear. This guide explains which accessory types are typically used with Phonak microSavia Art CRT dSZ, how compatibility works, and how to identify what you need before you buy.
What is Phonak microSavia Art CRT dSZ (in accessory terms)?
The name CRT is commonly used by Phonak to indicate a thin-tube / receiver-on-tube style fitting where the sound is delivered through a slim connection to the ear. For accessories, that usually means you will be replacing one (or more) of these parts over time:
Eartip (dome) or earmold that sits in the ear
Tube / thin tube (and the small retention pieces that keep it stable)
Receiver/speaker unit (if your version uses a receiver element near the ear)
Wax protection (filters/guards) that prevent earwax blockage
Because model names and fittings can vary by country and clinic configuration, the most reliable method is to identify the part currently on your hearing aid (see below) and match that system.
How compatibility works for Phonak microSavia Art CRT dSZ
Accessories are not “universal” across Phonak models. For Phonak microSavia Art CRT dSZ, compatibility is typically determined by:
Connection type (how the tube/receiver connects to the hearing aid and to the eartip)
Tube/receiver size/length (left vs right and length numbers)
Dome attachment system (how the dome clicks/grips onto the sound outlet)
Wax protection system (the exact filter/guard type used with your eartip/receiver)
If you are unsure, the fastest path is to compare the shape of your current outlet and the dome mount, or check any part numbers printed on the tube/receiver.
Common accessory types for Phonak microSavia Art CRT dSZ
Domes (eartips)
Domes are the soft silicone tips that sit in your ear. They affect comfort, feedback (whistling), and sound balance. Phonak microSavia Art CRT dSZ fittings commonly use one of several Phonak dome systems depending on the tube/receiver generation.
Choose a dome based on: fit (open vs more closed), size (small/medium/large), and the attachment style that matches your current setup.
Tubes / thin tubes
CRT-style fittings commonly use a thin tube. Tubes can be left/right specific and come in multiple lengths. A mismatched length can cause discomfort, poor positioning, or the hearing aid not sitting securely.
Tip: many tubes have a small marking for side (L/R) and a length number. Matching these markings is usually the safest choice.
Receivers / speakers (if applicable)
Some CRT configurations use a receiver element located close to the ear. If your Phonak microSavia Art CRT dSZ uses a receiver unit, it must match the connector type and the power level used in your fitting. If you are replacing a receiver, match the exact model/connector and side (left/right).
Wax filters / wax protection
Wax protection prevents blockage and loss of sound. Different Phonak eartip/receiver systems use different wax filters, so the correct filter is determined by the sound outlet you have (and sometimes by the dome/receiver system).
Signs you need a wax filter change: sound is weak or intermittent, the hearing aid seems “quiet,” or one side suddenly sounds different.
How to choose the correct accessories (quick identification steps)
Check your current parts: remove the dome and look at how it attaches (push-on, click-fit, or locking style).
Look for markings on the tube/receiver: side (L/R) and length numbers are common.
Compare the outlet shape: the end where the dome sits often reveals which system you have.
Match what you already use if it was comfortable and sounded right. Change style (e.g., open to closed) only if you are solving a specific issue.
If you are replacing parts because of feedback, poor retention, or uncomfortable fit, consider changing the dome style/size rather than only replacing the same type.
Common problems and what to replace
Whistling (feedback): try a larger dome size or a more closed dome style; check that the tube/receiver sits correctly.
Weak or muffled sound: replace the wax filter/guard first; then check for moisture or a damaged tube.
Dome falls off in the ear: dome may be stretched/old or not the correct attachment type; replace dome and confirm compatibility.
Hearing aid won’t sit securely: tube length may be wrong or retention piece is missing/worn.

FAQ: Phonak microSavia Art CRT dSZ accessories
Are Phonak microSavia Art CRT dSZ accessories universal across all Phonak hearing aids?
No. Many Phonak accessories look similar, but compatibility depends on the tube/receiver generation and the specific attachment and wax protection system.
How do I know which dome fits my Phonak microSavia Art CRT dSZ?
Match the dome attachment style to your current setup and then choose the size and openness (open vs more closed) based on comfort and sound needs.
What should I replace first if sound is reduced?
Start with the wax filter/guard if your system uses one. If the issue remains, check the tube for blockage, moisture, or damage, and replace if needed.
Do left and right tubes/receivers matter?
Yes. Many tubes/receivers are side-specific (L/R) and come in different lengths. Using the wrong side or length can affect fit and performance.
Can I switch to a different dome style?
Yes, as long as it is compatible with your attachment system. Switching style can help with feedback, comfort, and retention, but may also change how sound feels.
