Overview
A built-in microphone lets the Sonos Beam take Amazon Alexa voice commands, while the bar plays TV audio and music streamed over Wi-Fi. It links to the TV with the supplied HDMI cable or through the optical adapter, and a wireless subwoofer link is listed for adding bass later.
Voice control and Wi-Fi streaming in a single bar suit a living room or bedroom that wants better TV sound without extra boxes. Several spec lines contradict a plug-in soundbar, so treat the channel and battery entries with caution and confirm before buying for surround use.
Who it's for
Made for a living room or bedroom where the TV speakers fall short and a voice assistant is welcome. Households without Wi-Fi, or shoppers expecting a full surround kit in one box, should keep looking.
Pros and cons
- Alexa voice control built in
- HDMI cable included
- Optical adapter for TVs without HDMI audio
- Ethernet cable for a wired connection
- Bluetooth not listed
- No subwoofer in the box
- Several spec entries look like data errors
- Not water resistant
Performance notes
Sound depends on room size and placement, since a single bar has to spread audio from one spot below or above the TV. Voice control relies on the microphone hearing commands over playback, and streaming quality follows the strength of the Wi-Fi signal or the wired Ethernet link.
