Just as Amazon adds the whole-home audio to its Echo line of speakers, here comes the leader in the space with an Alexa-powered system of its own. The Sonos One Smart Speaker has built-in support for Amazon's voice assistant, with a six mic array and adaptive noise suppression to make sure your commands are heard correctly. Sonically, it has a pair of Class-D digital amplifiers driving its tweeter and mid-woofer, and it works seamlessly with your other Sonos gear, so you can control the music in any room using just your voice. In addition to Alexa, support for Google Assistant and AirPlay 2 is planned for next year. Available in white or black.
