How to use Apple Watch to MFi hearing aids for phone calls... without iPhone present!

I put a SIM into Apple Watch... works fine. But it does not connect to my (Widex) hearing aids, so I can't use it stand-alone away from an iPhone. Audio from the watch is insufficient to use. Without hearing aids, it's useless.

Hi Everyone, I am an audiometrist with Specsavers Audiology and I have some answers on these different devices. Any MFi hearing device will not connect to the apple watch directly - this includes brands like Widex, Signia, Rexton, GN resound and others I'm sure. There is one manufacturer that I am sure will work and that is Sonova who own Phonak and Unitron. They still employ classic bluetooth within their products and can be paired via traditional bluetooth pairing. This type of bluetooth does traditionally chew through battery life of hearing aids which is why LE bluetooth (MFi and ASHA supported devices) is now more commonly used by hearing aid manufacturers. We deal with most of the above manufacturers with no preference, there are many variables we use to select a device and should be discussed with the client based their needs. This is definitely worth bringing up with your clinician if its an issue and see what options you might have employing a compatible bluetooth streamer, if you're unable to return/exchange the devices. Good luck everyone
