I trialed a pair of Phonak Marvels last year and the molds were the C Shells, which are a 3D printed mold.
It was acrylic, but fit like a glove.
I preferred the sound of Oticon, so went to the ON S MiniRite, and the 1st 2 pairs of molds had the same issue, the left would slip, and occlude.
They finally came up with the same design as the Phonak C Shells, and are great, so check if you’ve had C Shells, and I understand Phonak offers a Titanium mold that may help ( $$$).
