With this blister of 10, you will have enough supplies to replace your domes regularly. This will keep your hearing aid clean, hygienic and perform as you have come to expect.
What are Phonak SDS 4.0 domes?
Domes are small silicone ear pieces that are placed on the speaker of a hearing aid. They ensure that sound is properly directed into the ear, while at the same time contributing to wearing comfort. Phonak SDS 4.0 domes are the latest generation of domes from Phonak and fit only on hearing aids that work with the Phonak SDS 4.0 receiver, such as the Marvel and Paradise models.
The Large Open variant is designed to keep sufficient ventilation in the ear. This prevents a closed-off feeling and makes your own voice sound more natural.
Compatibility
These domes are suitable for:
-
Phonak Marvel hearing aids
-
Phonak Paradise hearing aids
Important: The SDS 4.0 domes are not compatible with older Phonak domes. Always check that your hearing aid uses the SDS 4.0 receiver before ordering.
Benefits of the Phonak SDS 4.0 – Large Open
-
Comfortable fit
The silicone domes are soft and flexible, adapting well to the shape of the ear. This makes them comfortable, even with extended wear. -
Natural sound experience
The open structure ensures that there is sufficient ventilation. This keeps your own voice sounding natural and prevents a “dense” or “full” feeling in the ear. -
Hygienic and replaceable
Domes come into contact with earwax and moisture on a daily basis. Regular replacement is important for the hygiene and performance of your hearing aid. -
Easy to replace
Thanks to Phonak’s Click mechanism, you can easily replace the domes yourself. This eliminates the need to visit the hearing care professional each time. -
Handy pack
This blister contains 10 pieces, so you always have a supply on hand.
Why replace domes regularly?
Wearing hearing aids daily causes accumulation of earwax and debris. This can lead to:
-
Reduced sound quality
-
Irritation or itching in the ear
-
Shorter earpiece life
Therefore, Phonak recommends that domes be replaced every 4 to 8 weeks on average, depending on usage and personal circumstances. With this blister of 10, you are assured of sufficient supplies for a longer period of time.
How do you replace the domes?
-
Grasp the hearing aid firmly.
-
Carefully pull the old dome off the receiver.
-
Click a new dome from the blister.
-
Place the dome firmly on the receiver until you feel it is secure.
-
Make sure the dome is properly attached before placing the hearing aid in your ear.
Thanks to the SDS 4.0 design, this process is quick and easy, without special tools.
