I’ve been wearing soft silicone skeleton molds for a couple of years. Some days they’re comfortable, other days not. Location of discomfort varies, and never any visible irritation. Maybe my cartilage is sensitive. Given all that, and absence of feedback, I figured it’s me, not the molds, and redoing them is unlikely to help. But I got especially annoyed one day and decided to do something. Asked my audiologist what material they’re made of, and she said M2000 as in the chart below. She suggested trying the softer M25. Got them made using the same impression, and I’ve had them since Friday.
So far I’d say they’re definitely more comfortable, though time will tell. One difference I’m pretty sure about. These molds come with a thin little handle for pulling them out. On the previous ones and their predecessor pair, the pull handle broke off the very first time I tried to use it, because it’s pretty fragile and it took some force to get them out. But I can pull these super-soft molds out using the pull handle, probably because they flex enough to easily get past some constriction. I hated pulling the old ones out.
