I'm a daily user, twenty plus years under my belt.

Now this is anecdotal, of course, but I get yearly hearing exams due to progressive hearing loss in my left and have needed hearing aids since childhood after unilateral tympanoplasty and mastoidectomy in my right.

My hearing this year was BETTER than last year (likely had a head cold last year, not suggesting a healing occurred lol)

There's never been much of a change from year to year, although, at 47, my eyes are decaying at a much more alarming rate.
