AirPods libreated from Apple's ecosystem

I've wanted to try AirPods for my dad as hearing aids, but haven't done so because he would have to have the iPhone on hand. He's too old and blind to operate an iPhone. Can anyone here tell me how to take this awesome repo and make a hearing aid possibility for him with a simpler interface?

setting up hearing aids is a one time thing. then, the main adjustment is the amplification, which can be controlled by swiping on the stem. there is no need for an iphone for using it as hearing aids.
