I just got new hearing aids from the VA about 2 months ago - they are Signia brand and the connect to my Samsung Galaxy S20FE phone with no problem. When I got them my audiologist took the time to call Signia to verify that they were compatible. The 4 year old Signias that they replaced needed an external pendant to talk to my phone - I kind of prefer that because to answer a call I just had to push a button on the pendant; now I have to retrieve my phone and swipe the screen to answer a call.
These new ones also talk to a small streaming box that is connected to my TV set so I don't have to have the TV volume up at ear-splitting levels anymore!
