If you order the wrong size / type of dome but can return unopened and in a re-saleable condition we are happy to replace with the correct item, however we cannot accept opened packets that we cannot re-sell.
N.B. These domes are suitable for all Phonak and all Unitron RIC and Micro / SlimTube products (apart from Phonak Audeo M (powered by Marvel).
If you are using the latest Phonak Audeo M receiver wires (SDS 4) you will need to order SDS 4 domes instead.
The two versions of domes are incompatible with each other, the easiest way to check is to look at the tip of the Phonak receiver wire.
See the image to the right, if your receiver wire tip (once you remove your dome or custom tip) in appearance with the ridged effect looks like the top image (SDS 3.0) you should order the domes on this listing.
If it looks like the bottom image (SDS 4) then you should order these domes instead.
(The new SDS 4 domes are only potentially available and suitable for Phonak Audeo M (powered by Marvel) hearing aids supplied and fitted from end of November 2018, anything previous to that is definitely the domes as per this listing).
