I've been playing this game a long time, like back when Vandersteen had only two models....really one, but officially two. Anyway, my hearing back then was stellar, but after a lifetime of live sound, shooting sports, and other high SPL events, I have light tinnitus, and a definite disparity between right and left ears. So I realize I have ultimate limitations, but I also realize that my lifetime of critical listening has helped to overcome some of the actual loss. I still hear new things in familiar recordings.
Concentrate and enjoy the moments, they're still there.
