Bluetooth option doesnt seem to work. Arris 4k video box. Push button at back of box, it flashes blue then headphones to flash blur/red. Nothing over and over. No DIN plug to RCA plugs for my old headphones. Need hockey, not a miserable wife.
Arris boxes don’t support Bluetooth functions. You would need to use the tv audio out to feed the headphone receiver.
Your best bet would probably be to connect headphones to your TV or receiver if you have one.
