This is a work in progress. It is fully working at the moment. I am thinking about designing a board that can be dropped in with only few connection points. It is a BK3266 module with bluetooth 5.0 i have it setup to switch on the headphone on the switch when it comes on. There is 2 touch buttons on the back one will turn it on and off and the other is for paring.if anyone would like to know anything more ,just ask
