Bit a side question since OP mentioned company's name: anyone from Europe with Phonak devices with recently replaced earmold? I wonder if you got a soft silicone or something that appears to be some firm 3D printed material.

Mother uses hearing aids since end of 90s and most of the time it was in-the-ear but recently due to increased hearing loss she had to pick a new behind-the-ear device - still with button battery tho.

I wear BTEs and got new earmolds made by phonak this past summer, but I'm in the US. I'd classify them as firm silicone, and doesn't seem 3d printed. Seems like the same material as the previous molds (which I wore for almost 8 years).
