Well from reading posts I’m going to gather that a “more severe/profound” hearing loss dictates trying (first) a unvented soft hearing mold and testing to see if it works. I’m in Dani’s camp regarding issues with unvented mold and jaw movement (also walking) but its been a while since I’ve tried a unvented mold. Maybe eight years ago.
What I also find interesting is the depth of the “ear canal” mold. I’ve recently switched Audi’s but in the past (with old Audi) my ear canal (mold) section was made very long. And I’m not sure that’s ideal with a unvented mold, since the longer the mold the more it trigger occlusion with jaw movement. Just guessing here? A shorter ear can mold might allow for less movement when eating/walking etc. Maybe some here think I have this backwards, but the depth of a ear mold does play some role.
Just not sure how much.
