Just out of curiosity, have you ever had your hearing checked? Most of us....of any age, have significant hearing loss which we have just gotten used to. It turned out I had over 40% loss in my left ear (machine shop, rock and roll, firearms..typical American Male). I was amazed at what I was hearing again, and my wife is alot happier with the TV on only 1/2 the volume! I am hearing alot more out in the woods, too.
Alot of cheap "hearing aids" are only really, sound enhancers...think, turn up the volume, and dont really help in real world use. Actual quality hearing aids match the ranges you have lost to the aid. Amazing little things.
