I don’t know about Phonak but my OPN has a size 12mm dome, although this size is not available for open dome, only available for bass domes or power domes.

I figure if the OPN has size 12mm domes, the Phonak probably also has a size 12mm as well.

Thank you for the suggestion, I will look into that.
