I was not sure if these were the exact domes I need for my Phonak Audeo hearing aids because the image is a little blurry. I took a chance and ordered them and they are the exact match. Not only that, the price was better than just about anywhere else, and I received the domes in just a few days all the way from Canada to NE Tennessee. OmniHearing is now my go to place for my hearing aid supplies.
