Phonak and Unitron Domes – £9.95 per pack of 10 domes.
Please note – we only ship to UK postal addresses and no longer ship outside of the UK.
Available in SDS 3 and SDS 4 versions. The two versions of domes used on Phonak and Unitron hearing aids are incompatible with each other, the easiest way to check 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 SDS 3 domes. If the tip looks like the bottom image then you should order SDS 4 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.
Another way to think about it is this, if your hearing aids are anything before Marvel technology then you will need SDS3 domes, and Marvel and Paradise technology used SDS4 domes. For NHS hearing aids anything before Nathos Nova uses SDS3 domes, Nathos Nova uses SDS4 domes.
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.
