The kubu WiFi Audio app allows you to listen to audio from televisions or other audio sources that are equipped with the kubu WiFi device.
Public venues such as restaurants, bars, lobbies, etc may be kubu WiFi equipped or you can purchase small, low cost kubu devices to allow family members to listen to televisions at home with the volume turned down or muted to not disturb others.
To listen to a kubu equipped television over WiFi just connect your iOS device to the kubu WiFi network that appears and then launch the kubu app and start listening.
