There’s a thread I started that may be of interest.
Latency is the issue. If your TV has Bluetooth the KS10 will connect to it but the audio and video being out of sync may be more than you can deal with. It’s possible that Android TVs might adjust the two streams as the Google TV with Chromecast seems to do. I haven’t tested.
As has been noted, it’s a solution for a single viewer only.
