I've been using a pair of Eargo hearing aids to compensate for my general hearing loss due to age and years in a loud workplace environment. Their top model (around $3000) is made specifically for hi-fi enthusiasts. There are 4 preprogramed volume levels and you can adjust the bass and treble response on one or both ears for each of the 4 programs. They also have preprogramed algorithms for such things as conversation, crowd, theatre venues, etc. Control everything with their ap on your phone. Totally invisible, FDA approved, and rechargeable. Made a big difference for me. Have very limited high frequency hearing. Worth looking into.
