SCA604. Amazon Echo Plus

Echo Plus has a built-in Zigbee hub to easily set up and control
your compatible smart home devices, so your smart home can be set up without a separate hub. Alexa can be used to control compatible smart lights, switches, sensors, door locks, and more. Call almost anyone hands-free, instantly drop in on other rooms in your home, or make an announcement to every room with a compatible Echo device. With seven microphones, beamforming technology, and noise cancellation, Echo Plus hears you from any direction— even while music is playing. Premium speakers powered by Dolby play 360° audio with crisp vocals and dynamic bass response; you can also use your voice to adjust equalizer settings or pair with a second Echo Plus (2nd Gen) for stereo sound.
