Phonak and Unitron Domes – £9.95 per pack of 10 domes.
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 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.
All Phonak and Unitron thin tubes except SDS4 tubes use SDS 3 domes, SDS4 tubes must use SDS4 domes. Older Phonak and Unitron RIC receiver wires use SDS 3 domes, the newer Phonak and Unitron hearing aids use SDS 4 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.
