The new Sonos One Smart Speaker has Amazon Alexa built right in for the ultimate hands-free control of your music. You can use your voice to select songs, turn up the volume, and more–all while you’re doing other things. You’ll get all of Alexa’s best features, like checking news and traffic and managing smart devices using a single Sonos speaker. When you’re ready to expand your Home Sound System sound system, you can wirelessly connect your Sonos One to additional Sonos speakers for complete multi-room listening.
