This is the smart speaker that raises the audio and aesthetic experience to a level never seen before. The WiFi, Alexa, and Bluetooth enabled 20-watt smart speaker pairs two active drivers with two passive radiators to produce immersive, room-filling sound. You can use Alexa voice commands to stream music from services such as Pandora and Spotify, or you can pair it with a Bluetooth device to take your music on the go. The speaker looks as good as it sounds thanks to its refined craftsmanship using machine edged aluminum, finely stitched Japanese speaker fabric, and genuine leather panels. Volume and music controls are accessed with an analog knob and capacitive touch buttons on the speaker, Alexa voice commands, or a free app for iOS and Android devices. Multiple speakers can be paired to expand the immersive audio throughout your home. Rechargeable battery provides up to 10 hours of music playback on a three-hour charge via USB-C cable or by placing the speaker into its leather AC-powered dock. Includes canvas travel case. Blue/Tan. Speaker: 83/4" H x 3" diameter; dock: 1" H x 3 3/4" diam. (1 3/4 lbs.)
