Bob, you can pair one Bluetooth headset at one time; however, you can turn on both the TV speaker and Bluetooth headphones at the same time. When this function is active, you can set the volume of the Bluetooth headphones higher than the volume of the TV speaker. Here is how to play both TV and headphone sound simultaneously: Home > Settings > General > Accessibility > Multi-output Audio. From there, select which Bluetooth device you want to play audio. ^Gina
