I crafted a new music program for my Oticon More 1 based on the Phonak Lumity. I used NAL-NL2, which seems to be the closest option Genie 2 offers to Phonak’s proprietary fitting formula. Then I tweaked the frequencies I know that need to be lowered a bit. This early version is already considerably better than all my previous experiences with MyMusic. It sounds great for both streamed music and my two guitars.
As it is often stressed on this forum, much of hearing improvement comes from good implementation. I guess the same goes for manufacturers and their “modeling” choices (fitting formula, compression rates, gain targets, MPO, etc.). I will be sure to peruse other’s companies fitting software from now on
