Thanks for the advice and encouragement.
I don’t think I’m reacting to the silicone, I think it was just the extra pressure of the larger double domes I tried first. They also went deeper into my ear canal, and weren’t vented. I don’t think I can tolerate non-vented, although I’ll probably give them another try just to make sure.
At the moment I’m getting along fair, by adding a concha lock (leash?) on the left side, which works pretty well. Right side it seems the shape of my ear just doesn’t want to keep the lock In place.
I’m guessing a bit, but it seems the shape of my canals don’t give the domes a good place to sit, there’s nothing to keep them from just pushing out.
I’ve got custom fitted molds coming, suggested by a friend here locally who’s got many years of experience with HA’s, and several good comments here about them.
The aids themselves are working out well in spite of the difficulty with the domes etc.
As many have advised, It takes time and experimentation to get it to all work!
