MJCMT...my ears have been subjected to being attached to a head that's been in the music biz for over 5 decades, and they work fine. I don't mix these small venue live shows to ear blasting loudness so that's not hard on my ears at all, and the styles of music have ranged from Jim Campilongo and Julian Lage to The Baltimore Consort and Bill Charlap (not on the same bill, but you get the drift). Decades of electric guitar likely did the most damage, but other than tinnitus that really doesn't bug me much and some very high frequency loss I can still hear better than most geezers.
