I am trialling the Lumity 90s, having tried Marvel and Paradise without too much joy. But I reckon success is more down to a good fitting custom mold that anything else.
I have had at least 5 sets of custom molds made that just start to move after a while. I decided to see a different HAD (same company different location) and I showed her the custom molds that I had previously had made (by Phonak) and were Ok for a few hours but kept moving enough for the sound quality to degrade noticeably.
She immediately looked at my canals and remarked how large the canals were. She took an impression and sent it off to Phonak. The molds came back but she immediately returned them to Phonak as they would clearly have been too small. Whatever she then said to Phonak worked as the latest molds are much better. At first there was some minor movement in the right HA but I reckon the canal has some elasticity and that is much less now. So after many attempts over several years and much frustration, I really do feel that I am getting closer to a good fit. Without a good fit, tweaking the software is a fools game.
The key thing that I did that showed the issue was to show the HAD my old aids (PhonakVirto Q90 ITE) and compare the size to the shells that came back.
The previous HAD simply said that they can’t make molds so big for RICs which looking back was just BS. The moral of the story being that good custom molds are vital as well as having a good HAD.
I am still working on getting the Autosense progs to be useful. For example, going into a bar with music playing, you DO NOT want the aids to go to Music mode!
