Correct! Altho my outer ear is pretty stable, once you get to the ear canal DOORWAY (does that have a name?) it swells up and down throughout the day. It’s not like I’m a sodium addict, but that is just an area of swelling that’s come on with aging.
I get what you mean about the friction element of a softer layer applied to a hard plastic mold. Hmmmm. What we need here is a SHOE horn for the EAR canal. Yes, a little spoon-shaped device to literally ease that hard mold into the ear.
(If it weren’t so ridiculous, I’d add that little shoe horn to my Dream Features list - one sold with every HA purchased.)
