Still would appreciate responses but might of answered my own question.
Lumity is very similar to Phonak’s last generation (Paradise), but adds StereoZoom 2.0 and SpeechSensor, which together deliver clearer speech in background noise, according to Phonak.
Well if that’s the only (main) difference between two aids (and that’s currently stated for only the lower powered rechargeable battery Lumity), I’m not sure anyone should discard their current Naida Paradise aids for Naida Lumity. But if anyone is considering new power aids for the first time then it appears the Naida Lumity would be a better choice to buy.
For those currently using the Naida Paradise aid, I’d wait until 2025 for possibly a completely new power aid coming out. Since the Naida Lumity probably isn’t worth the costly short term upgrade.
