Hi

To pair your Bluetooth headphones to your Samsung Smart TV:

Put your headphones in discovery mode. The way to do it will depend on the brand of your headset. On Apple AirPods, place the earbuds in their charging case and leave the lid open, then press the button on the back until the status LED starts flashing white. On a Tozo earphone, you simply remove the earphones from their charging case.

Once the headphones are in discoverable mode, turn on your TV and press the MENU key on the remote. Then go to Sound > Speaker List > Bluetooth Audio and select your headphones.
