I have brand new Pardise rechargeable hearing aids.
My audiologist gave me an assortment of domes. He didn’t take a wax impression and make custom domes for me. I have no experience with those for Phonaks.
He did give me an assortment of 4 different dome sizes. All were what I think are open domes except for the smallest. It had no perforations at all and only covered the end of the receiver? in the ear.
I am using the largest open dome he gave me now with perforations all around. They are very comfortable. The other ones he gave me to try were all smaller. I tried them all and have been using the largest ones for about a week now. I believe they are the ones he set up my hearing aids with almost 2 months ago.
When I was using my B70’s the previous audiologist put on power domes. I hope that’s the right name. They had no perforations, and had two seals. They were awful. They set the B70’s up with that. after 2 days I changed back to open domes after being told in no uncertain terms that I wasn’t able to hear my wife. I went back to the audiologist who never reprogrammed the hearing aids.
My story isn’t important here; however, I feel that there are many choices. However, I think the right one depends on the gain of your hearing aids, your hearing loss and whether you need help with feed back.
