I’m wondering how much it would cost to get new custom full shells for a pair of used hearing aids, like this pair of Oticon Alta Pro’s3. These don’t say what power the are 75, 85, or 90. So that’s one problem.
Not that I want to do this. I wear . I’m just curious.
Also could the re-shell be done with a home kit and a Lab?
