My first pair of hearing aids opened up a lot of sound that I was missing, and even a few that I don't mind missing. My second set was a great improvement adding the convenience of an interface with my smart phone, but replacing the batteries was a hassle. My latest set, rechargeable, much improved sound quality, smart phone interface, multiple programs and the ability to allow my audiologist to interact remotely if needed makes them so much better.
The technology in this area truly is continuing to handle my hearing issue and open a more friendly world of sound. I do wish they could eliminate the impact of cars with sonic sound vibrations. Can't have everything I guess.
