iOS 11 does not work correctly with MFi hearing aids and Apple MUST fix this ASAP, right?

I have used iPhones and iPads for many years. I am a disable veteran and rely on Oticon MFi hearing aids to function. Since the early releases of iOS 11 beta, which I tested, these hearing aids have not worked correctly. It is probably related to Bluetooth and how it is implemented.

iPhone 8, iOS 11.1

Hi SpunkyinAZ. The problems that I'm having with my Resound Line 9 MFi hearing aids are similar to yours. With iOS 11 on an iPhone 8, they are very slow to make a connection either on a call or when streaming a talking book. The connection is then extremely erratic, switching from aid to aid and sometimes failing totally and reverting to the phone's speaker. I have worked round the problem by buying a device that Resound call a clip; I think they are generically called streamers. This small device has to be worn and its job is to sit in the communication between the iPhone and the hearing aids. The iPhone is paired with the clip by standard b bluetooth and the clip is paired with the hearing aids using the low energy bluetooth the MFi hearing aids use. This means that the low energy bluetooth connection is between two devices made by Resound and removes Apple support from the picture. The iPhone communicates with the clip as if it were a standard bluetooth headset. The clip cost me around £200. I'm now pretty confident that the problem is with Apple withdrawing support for older versions of the MFi hearing aid standard, so it may be the those of use who have older models (mine are just three years old) may never have Apple fix this. I'm trying to confirm this but I did learn it from an authoritative source. Sadly, it's common practice for the IT industry to stop providing support for older standards. Think of all those different floppy disks that our older computers used. I think we'll discover that hearing aids are no different. They may all look the same, but internally they will be using different standards to communicate with phones as the technology evolves and it's very unlikely that Apple or other manufacturers will support older devices forever. We may just be unfortunate in having purchased or acquired devices that were among the last to use an older standard. The good news is that streamers aren't terribly expensive and they seem to work.

ChrisJ4203, thanks very much for getting back on this. My Linx hearing aids were bought about three years ago, which is why I was particularly disappointed that iOS 11 no longer streamed reliably to them.

It's interesting to learn that your hearing aids may also be the original Linx model. I suppose that there may have been some changes during the lifetime of the Linx model. I'd be very grateful if you could let me know the model number that is reported at Settings/General?Accessibility/MFI hearing devices. My LiNX 3d hearing aids show up as LT961-DRW, for example. My original Linx 9 hearing aids show as LiNX 961. It would be interesting new information if your hearing aids appear to be the same as my Linx hearing aids since that would suggest that I need to revise my analysis!

Thanks again, Brian
