Sonos One smart speaker review: Sonos and Alexa, a match made in heaven

Sonos has multi-room audio down to a science, but it desperately needed a speaker capable of voice recognition if it was to fend off the veritable flood of smart speakers coming to market. The Sonos One is that speaker. It sounds better than the last entry-level Sonos speaker, it's compatible with Amazon's Alexa digital assistant, and it will be compatible with Google Assistant soon. If you already have Sonos speakers in other rooms, you can control all of them with voice commands with the addition of a single Sonos One to your network. And once you have that, you can control any Sonos speaker from any Amazon Echo.
