Hey! You can connect Bluetooth headphones to the R85H TV. Refer to your headphone's user manual for how to pair. Once paired to the TV, go to: Home > top directional key Settings > All Settings > Sound > Sound Output > Bluetooth Speaker List. Choose the headphones you wish to use for sound output. ~ Samsung Ambassador

Hi Sdave, in short, no. Multi View, available on Samsung’s M80H Mini LED Series and above, allows you to display two types of content on-screen at once. You can view an app or HDMI source on the left, while mirroring your smartphone or casting from a compatible app on the right. While two HDMI sources can’t be displayed together, Multi View gives you the flexibility to combine streaming, live TV, mobile content, and more – side-by-side. ~ Samsung Ambassador

Hi Emptycods,

The M70H does not feature an optical output.

Hello Tony! To pair your Samsung Sound Tower speakers, first power on both speakers. On the primary speaker, press the Group Play or Stereo Pair button (the button name varies by model) until pairing mode is activated. Then press the same button on the second speaker. Once the speakers successfully connect, the display or indicator lights will confirm the pairing status. After pairing is complete, connect your phone, tablet, or other audio source via Bluetooth to the primary speaker, and audio will play through both units. This can also be done through the Samsung Sound Tower App.
