The main difference between Sonos Beam and a regular soundbar is their connectivity options. While both products provide high-quality sound for TVs, the Sonos Beam offers greater flexibility. The Sonos Playbar requires an optical connection to the TV, while the Sonos Beam uses an HDMI ARC port, which is the preferred choice for most setups. The Beam also includes an optical adapter, allowing it to connect to TVs without an HDMI ARC port. Additionally, the Sonos Beam has a more compact design compared to the Playbar, making it suitable for smaller spaces. It has also been specially tuned by Oscar-winning sound engineers for optimal sound quality. Furthermore, the Sonos Beam can be expanded to create a multi-room streaming system, allowing you to enjoy in-depth sound throughout your home.
