Thanks to eleven sound channels facing various directions and the Dolby Atmos and DTS:X technologies, the elite Samsung speaker system achieves a totally immersive effect. The two included rear wireless speakers channel the sound sideways and upwards for it to reflect from the ceiling. Then, the speaker syncs with your Samsung TV and activates the Q-Symphony function to combine the power of integrated TV speakers and this Soundbar. Thus, the sound becomes ever more immersive. As you sit on your couch in front of your TV, you have a feeling that the sound is all around you like in the real world. If you would like to play black music from your smartphone with this powerful speaker, just touch the surface of the speaker with it. The smart device will vibrate and connect, taking over play-back of any premium quality audio. You can also use a remote control or a voice assistant to control your speaker.
