Currently staying with the in laws, daughter is sleeping in the same room with us so we couldn’t watch TV.
I connected my wife’s AirPods to the Apple TV to watch tv and noticed I could connect another one, so I borrowed my sister in laws AirPods and connected them and both work at the same time. So now we can watch TV together when daughter is asleep.
It only works with apple audio devices, so looks like I’ll pick up some new AirPods for myself!
