As is to be expected at a lower price, the new Sonos soundbar will omit certain features like Dolby Atmos, and it lacks built-in mics for voice assistant functionality. Sonos will position this as a soundbar for TV and music, leaving the smarts to its pricier siblings. In fact, internal specifications suggest there’s not even an HDMI port on this product (only an optical cable comes in the box). That limits the new soundbar to Dolby Digital surround sound. You’re still able to expand it to a 5.1 system if you own other compatible Sonos speakers.
