Interesting topic.Being a musician as well, Music is by far the most complicated thing for modern devices compared to the older analog hearing aids.
Currently I still have a couple of Phonak Dalia MicroPaids which are setup lineairily (no automaticshaping as far as possible). Speach recognition is at most average, but I have little compaints about disturbing behaviour when playing on stage.
I am not a singer but play electric guitar and as such my aids need to handle clean playing as well as distortion in a band.
I am about to try Phonak Paradise soon, though I indeed also read about Oticon More and am very curious about those.
Opn was no option for me since I want direct bluetooth connectivity to and from my android phone and other bluetooth devices.
As far as I know the More will have a need for asha protocol just as many others. Phonak is the only one with native bluetooth available. And since on stage we use in ear monitoring (which I now use with a neckloop and telecoilinstead of earbuds), I want to be able to put a bluetooth transmitter on that portable receiver and connect it straight to my devices.
So based on this latter, I still think the paradises are the only way to go for me. If not, I’ld be happy to hear this.
