Hi Andy welcome to the forum.
Yeah, I’m not player/singer, but an avid listener, attend a lot of classical concerts, and part-time/amateur luthier for cellos and guitar/bass. So my HAs performance with music was non-negotiable. I tried Phonak Lumity and Paradise, as well as Orticon Real - none of which made the cut. Eventually, I found what I was looking for when I trialed Widex Moments. Their higher sampling rate provided much needed clarity, and the Puresound ZeroDelay (though it’s actually 0.5ms) lag make the performance with music like getting the hearing back.
As to HCP’s not being music aware/oriented… it’s sad but true. It’s like their training is to stay away from tinnitus and music optimization. Nearly all brands have dedicated Music program, in which they typically have feedback suppression reduced/off and have increased/reduced compression - they can be a mixed bag! They can be fine tuned though and is where usesr opt for DIY than working with an audi that doesn’t have that background. Performance with music is still limited to internal hardware - which is Widex’s unchallenged advantage. They should be on your shortlist!
