As it turns out, there will soon be an option for people to have sound relayed directly to their hearing aids via their Apple (iPhone, iPad, etc) product, without the need for an intermediary device such as the Oticon Streamer, which I just discussed this past week. According to the Reuters article linked above, Starkey Technologies is also working on a hearing aid that will work similarly for iPhones but there's no details as of yet.
It sounds like GN ReSound may be at the forefront of "iHearingAids," but it does remain to be seen whether the elderly market for hearing aids will actually want to take advantage of the technology. I think it may take a few more years - for people in their thirties and forties now - before this kind of connectivity is basically expected.
