Hansaton 4.0 domes
Hansaton 4.0 domes are replacement earpieces for compatible Hansaton hearing aids using the 4.0 receiver or thin tube system. The dome sits in the ear canal and helps provide the correct balance of comfort, ventilation and acoustic sealing for your hearing aid fitting.
At Japebo, you can find Hansaton 4.0 domes in different styles and sizes, including open, vented and cap domes. The correct dome should match the type and size already selected for your hearing aids.
Choose the right Hansaton 4.0 Dome
The dome plays an important role in both comfort and sound. A more open dome allows greater airflow through the ear canal, while a more closed dome creates a stronger acoustic seal.
Your hearing care professional normally chooses the dome according to your hearing loss, receiver strength and individual ear shape. For this reason, you should generally replace your existing dome with the same type and size.
Hansaton Open Domes 4.0
Open domes 4.0 have ventilation openings that allow more natural sound and airflow into the ear canal. They are commonly used in fittings where less acoustic sealing is required.
Open domes are available in several sizes so the fitting can match the shape of the ear canal.
Hansaton Vented Domes 4.0
Vented domes provide more sealing than an open dome while still allowing some ventilation. They are often used when the hearing aid fitting requires more amplification without completely closing the ear canal.
This makes the vented version a middle option between an open dome and a more closed cap dome.
Hansaton Cap Dome 4.0
The Hansaton Cap Dome 4.0 is the smallest and most open option in the Hansaton 4.0 dome range.
Its compact design is intended for fittings where only a minimal earpiece is needed at the end of the receiver. Because it provides very little acoustic sealing, it allows a more open and natural feeling in the ear canal.
The Cap Dome should only be used when it matches the fitting selected for your hearing aids. If your current setup uses an open or vented Dome, do not switch to a cap dome based only on size or comfort, as changing dome type can affect the acoustic response of the hearing aid.
Hansaton Receiver 4.0 compatibility
Hansaton 4.0 domes are designed for compatible Hansaton hearing aids that use the SDS 4.0 receiver and fitting system.
Hansaton has used the 4.0 system with hearing aids including selected AQ sound XC, sound XC and AQ sound XC Pro models.
The Receiver 4.0 system is available in different power levels, and the suitable dome can depend on the receiver fitted to your hearing aid. Hansaton documentation lists Standard, Moderate, Power and Ultra Power receiver options within the 4.0 system.
If you are unsure which receiver generation your hearing aid uses, compare the replacement dome and receiver with your existing parts before ordering.
Do not change dome type based only on size
Two domes with a similar diameter can still have very different acoustic properties. Open, vented and cap domes allow different amounts of sound and ventilation through the ear canal.
Changing from one dome type to another can therefore change how your hearing aids sound and may affect the fitting. If you are replacing worn domes, choose the same style and size as the ones currently fitted unless your hearing care professional has recommended a change.
When should Hansaton 4.0 domes be replaced?
Check your domes regularly for earwax, damage, hardening or discolouration. Replace them when they become worn, loose, blocked or no longer sit securely on the receiver.
If the sound from your hearing aids becomes weak or muffled, also check the wax filter in the receiver. A blocked wax filter can reduce sound even when the dome itself looks clean.
How to replace a Hansaton 4.0 dome
- Gently remove the old dome from the receiver.
- Check the receiver and wax filter for earwax or damage.
- Take a new dome of the same type and size.
- Push it firmly onto the receiver until it sits securely.
- Check that the dome cannot easily come loose before placing the hearing aid in your ear.
Never use a dome that does not attach securely to the receiver.
