Unfortunately, there are no audiophile hearing aids. The IEM’s, such as the ASI’s would work for voice also but are ear buds with a small belt pack so not inconspicuous. I also read that while other voices sound fine, your own voice sounds weird.
Quality hearing aids are very small and inconspicuous, but are designed for voice. They have music settings to improve music listening and help a lot for listening to music for those with hearing loss.
There is no perfect solution. For me, I think my best solution is hearing aids for the real world and the ASI’s for music. If only one purchase, I would choose hearing aids. However, IMHO doing nothing is not a wise choice.
Side comment, some studies have shown a link between untreated hearing loss and dementia. With dementia and untreated hearing loss in my family, my choice was easy… and my music sounds much better!
