The Bose Soundbar 550 is a compact smart soundbar featuring Dolby Atmos and proprietary TrueSpace technology for fully immersive, three-dimensional sound. The acoustic architecture includes five transducers, with two firing upward to reflect sound off the ceiling, creating a captivating surround-sound experience that spreads audio horizontally left, right, and forward, as well as above.

TrueSpace technology intelligently analyzes non-Atmos signals like stereo or 5.1 content and upmixes them to create an immersive multi-channel sound experience, separating instruments, dialogue, and effects and placing them around the room. The soundbar supports wireless music streaming via Wi-Fi, Bluetooth, Apple AirPlay 2, Spotify Connect, and Chromecast built-in, with access to integrated music services and internet radio through the Bose Music app.

The soundbar features AI Dialogue Mode for enhanced voice clarity, and can be controlled via the included remote, the Bose Music app, or voice commands. It measures 27.34 inches wide by 2.21 inches tall by 4.09 inches deep, with a sleek matte black top surface and perforated wraparound metal grille. Connectivity includes HDMI eARC/ARC output, optical input, analog input, and Bluetooth. The soundbar can be expanded with optional wireless bass modules and surround speakers for a complete home theater system, and supports Bose SimpleSync for pairing with compatible Bose headphones and speakers.
