There are some really customizable hearing aids available these days. Like you, I am blessed to not need them.
My sister is a PhD level audiologist who spent her career in clinical work and graduate teaching, so she is literally tuned in. I try to stay current myself, having completed a graduate degree with a focus on acoustics and noise control 48 years ago.
Hearing changes are real, but usually gradual. So we adjust and compensate. My biggest challenge is my wife’s soft sweet southern soprano drawl. If she is not looking at me, beaming her voice at me, I may miss what she says. Sometimes this is “convenient.”
I know from testing that my hearing responses above 15 kHz are suppressed compared to 50 years ago. Lucky for me there is little music up there. But shimmer and sparkle are affected by this loss.
When comparing equipment, the evaluation is always relative. Even comparing live to reproduction, if the same person listens to both, the preference that emerges is legitimate for that person.
Speaking of comparing live to reproduction, now that there is less fear of Covid, more live events are scheduled.
I find myself in the audience several times every month. Amplified performances, with drum booths on stage, bass, guitars, vocalists etc can be quite complex to unpack in the live setting. The best seat is usually next to the mixing board.
Oftentimes, the home system beats the live performance. Especially on drums. The booth just creates a thick veil on the natural sound.
But I’ve been in discussions after the fact, and many listeners hate live drums because they can be so dominant. The booth allows the drums to be brought down in the mix.
It’s just stuff. I like mine. I hope you like yours. I probably like yours too.
