I have ReSound hearing aids that I got from Costco. They work fine and connect to my iPhone. As near as I can determine, they use a non-standard version of Bluetooth to communicate. I have tried to connect them to my Windows 10 computer, but no luck. I can pair them via Bluetooth but they never show up as a sound device. A standard sound device like Bluetooth headphones would show up automatically. You can use these hearing aids fine with iOS and Android devices, but I believe they do not work with Windows devices, and likely not with Linux or Mac either.
