15) There are no instant setting options available to change to the appropriate environment
Do you mean multiple programs, and possibly automatic switching? Because I know I've had aids that have done that. My previous set of aids (Phonak) had 3 programs, and I'm told the generation after that (same line, new model) switched automatically. My current aids don't exactly switch programs, but they do dynamic noise filtering, so they do adapt the the environment. And some of the current Oticons (not sure about other brands) have multiple programs - I think you can have them switch automatically or set it to manual only, as you wish.
