I have hearing aids, and they cost $3000. Insurance did not cover them.
Amazing that something as advanced as an iphone costs like $600 or so but hearing aids are way expensive. Of course, for that price you get the aids, 2 years of warranty and replacement cost if they're lost, hearing test, programming the aids. Worth it? Meh.
The aids don't just boost sound, they boost sound at the frequencies you don't hear well at. They are fully digital and have some "speech in noise" capabilities. They will probably give you, at best, 50% of your old hearing back. My hearing was so bad, I needed to do something.
