To those of you who wear them ; how often do you need to replace the ear mold ? I wonder if there's any way to tell how reliable the manufacturer is at making the molds ? My audiologist said the maker she uses was very good at it when they were local. They relocated to another state, and now, "don't seem to know what they're doing". Don't know who to rely on, now. I feel like going to all those trials hearing aid dealers offer, one after another, & see what I come up with. Take all the hearing tests they offer,compare one to another. Maybe, just maybe...I'll find someone competent. Hearing is very important, after all.
