Dani - you post was very insightful. I’m all for “better hearing” and if wearing a unvented soft mold improves my hearing level great. I’ve just worn hard shell hearing aid molds since day one and gotten used to them. I did not have a chance to put soft molds in by ear but when I tried to remove them - it was hard. With acrylic molds you push on the bottom part of my back ear and molds pop out. That didn’t happen with soft mold so the (not glued) tubing came off hearing aid.
I’m tempted to take something to chew on when I test the unvented soft molds in my Audi office. But I’ll probably hold off until I come home and start the trial period. You might be right regarding the relationship with a unvented ear mold and jaw movement. But other then “mold depth” entering ear canal, I don’t see how you could adjust a hearing aid mold to jaw movement.
