I guess the actual answer is that I should call my audiologist and see what she says.
However, thought with the many person-years experience of folks on this forum, it would be good to get a “second opinion” - (and a third, fourth, fifth, etc., ! ).
My left external mics were defective, turned the whole HA with receiver, mold and all into the audi and she said, “We’re going to send the whole thing off to ReSound and see what they can make of it.” I got a replacement HA back but I would have presumed that she would have kept the receiver, wire, and mold herself while ReSound inspected the body.
Just about the first day I cleaned the mold on the returned HA with my Jodi-Vac, I noticed that there was a small semi-circular flap flush with the rest of the surface of the mold and as the tip of the syringe vacuum needle runs over the area, the flap can be popped away from the rest of the surface of the mold, exposing a “rawer” area underneath. The flap is about as wide as a small power dome, 6 mm or less in the center of one of the lateral sides of the mold. The two “gestalt” things are the flap that comes loose almost looks like a different material from what’s underneath, a “skin” (??) formed by curing the silicone mold when it was made? - and the other amazing this is how perfectly circular most of the flap is.
Normally the flap is glued flush against the rest of the mold body and only disturbed by the Jodi-Vac needle or by wiping the mold with a Q-tip or alcohol wipe. I’m wondering if the fix is to just cut the flap off or to try to glue it back in place? My main concern is that as time goes by the gunk that accumulates under the flap and is difficult to thoroughly clean away is going to be a source of problems.
Any suggestion as to what to do would be welcome. I’ll see what my audi has to say. I’d hate to pay another $100 for a new mold if the current left one, other than my “gunk” concern, is perfectly functional. The mold passes the feedback test with flying colors and lets very little if any sound leak out between the mold surface and my ear canal, as the flap is normally flush against the rest of the mold surface when I am wearing the HA.
The very regular shape of the flap makes me think that it must have something to do with the manufacture of the mold. It’s hard to imagine post manufacture what could have loosened such a regular geometrical bit of mold “skin.”
