I never turn mine off while I am wearing them. They filter out loud
noise. I turn mine off at night when I go to bed and I open the battery
door. I think that is important. My aids are 12 years old and they still
work very well and they have never needed any repairs.
I won't tell what brand they are because I don't want to advertise the
brand. Because I was supposed to get free batteries for life and they
cut me OFF after about 7 years. Of course, that is the dealer doing
that. I should write to the hearing aid company and tell them what this
dealer did. I paid that dealer $6,800 for a pair. Now when I go to a
dealer, a set runs about $4,000 and one told me "WOW, we don't even have
hearing aids that cost that much and THAT was 12 years ago!
