A:Answer You can download the free Roku app on your smart phone or tablet to use voice search, voice control, and experience private listening. To enjoy private listening you simply click private listening in the app, and attach headphones to your smart phone or tablet. Or you can use the 3.5 mm headphone jack in the back of the TV to connect standard headphones/Bluetooth headphones with a transmitter. Hope this helps. Thank you, TCL Customer Support
