I guess it's different for different persons. Everybody tried to convince my stepfather for years and he didn't... listen (ahem, sorry) even if he has no problem paying for the aids. When he finally accepted to wear them, the situation has been pretty much what you describe. So I would really appreciate if you could remember or ask the name of the working ones.
