The Sonos One offers significantly better music quality than your average Bluetooth or smart speaker without breaking the bank and includes the full Alexa experience. That means it's the first Sonos you can control with your voice. It's also a great first step into a multi-speaker setup for your home. The voice controls may have a few bugs to work out, and Spotify isn't available with full voice control just yet, but the more services and features will be added over time -- there's no reason not to dive in now.
