Yes directly to the aids from my iPhone using MFI.
I also have a Resound Multi Mic that I use to stream from my Mac into my hearing aids, but I think the sound quality is not as good as MFI streaming from my iPhone, although it’s hard to compare directly as the streaming program is different to my music program. But I did recently make exactly that assessment.
I don’t know how the bit rate varies between Phonak and Resound. I didn’t like Phonak when I owned a pair a few years ago, although they were better than Widex that I also tried three different times (I bought two different pairs so did give them a good try). The Resound Quattros weren’t good for music in retrospect, but the Ones are much better. But I know people in the HiFi community that I’m also in who prefer Phonak to Resound.
I do spend quite a lot of money buying new hearing aids, about one new pair a year. I know I’m lucky to be able to do that without worrying about it.
