The Sennheiser RS 120-W headphones cannot be connected directly to your Samsung QE65Q70T TV via Bluetooth as they do not support Bluetooth. Instead, you need a connection via RCA or 3.5 mm jack to connect the headphones to an external device such as a soundbar or an amplifier, which is then connected to the TV. If your TV does not have a 3.5 mm connection, you can use an adapter or an optical connection to send the sound to another device that supports the headphones.
