Product Description:
Effortlessly enrich your entertainment experience with the latest generation of Beam, now with Dolby Atmos. Enjoy panoramic sound for shows, movies and games when the TV is on, and stream music radio and more when it's off.

• High Quality, even at low volumes
  Advanced audio processing ensures balanced sound from wall to wall at any volume level. When you want to watch TV but need to keep it down, turn on Night Sound in the app to reduce the intensity of loud effects and enhance quieter ones.
• Crystal clear dialogue
  Oscar-winning sound engineers helped fine-tune the soundbar to make sure you hear every word and can always follow the story. For even greater clarity when characters whisper or the action intensifies, turn on Speech Enhancement in the Sonos app.
• Tuned to perfection
  Trueplay tuning technology adapts the sound for the unique acoustics of the room so your content always sounds just the way it should. Requires iOS device.
• Breeze through setup
  Go from unboxing to unbelievable sound in minutes with only two cables and step-by-step guidance from the Sonos app.
• Beam, evolved
  A faster processor enables support for Dolby Atmos and creates two new audio paths for a virtual sound experience. Updated with a precisely perforated grille, Beam looks just as good as it sounds and blends seamlessly into your home.
• Hands-free help
  Ask Amazon Alexa or Google Assistant to set timers, check the news, control your smart home devices and more. Easily mute with the press of a button to turn off the mic. The LED light will also turn off so you know your voice assistant isn't listening.
• Made for music
  Stream music, radio, audiobooks and podcasts from all your favorite services with detailed stereo sound that fills the room.
• Dramatically realistic
  Dolby Atmos maps sounds in space for a 3D effect so you experience planes as if they're flying overhead, hear footsteps moving across the room, and feel the score all around you. Requires a TV that supports Dolby Atmos and Atmos-encoded content.
