Phonak and Unitron Domes – £6.95 per pack of 10 domes all variations except £16.95 for per pack of 8 EasyGuard domes.
Please note – we only ship to UK postal addresses.
Available in SDS3, SDS4 and EasyGuard versions. Older SDS3 domes are NOT interchangeable with newer SDS4 and newest EasyGuard domes used on Phonak and Unitron hearing aids, but SDS4 and EasyGuard ARE interchangeable with each other. The easiest way to check for compatibility is to remove the dome and look at the tip of the receiver wire / tube.
See the image to the right, if the receiver wire tip looks like the top image you need to order SDS3 domes. If the tip looks like the bottom image then you should order SDS 4 or EasyGuard domes.
Phonak and Unitron thin tubes also have the same overall design as receiver wires, apart from the fact that they do not have any colour, they are clear transparent.
If your hearing aids are older than Marvel technology then you will need SDS3 domes, and Marvel, Paradise, Lumity and Infinio technology uses SDS4 and EasyGuard domes. For NHS hearing aids anything before Nathos Nova uses SDS3 domes, Nathos Nova uses SDS4 and EasyGuard domes.
Why choose the more expensive EasyGuard domes over SDS4 domes? EasyGuard domes are specially designed to offer extra protection from earwax using a sealed, sound-transmitting membrane. This innovation simplifies hearing aid maintenance by reducing the need for changing the wax guard as the membrane acts as a built-in wax barrier. This leads to easier cleaning and less hassle while also helping to extend the life of the hearing aid.
Please take care when ordering that you know what size and type of dome you require. If in doubt please ask our advice or alternatively the company that supplied your hearing aids.
