About 3 inches (76mm) wide and 1.5 inches (38mm) tall, the Echo Buttons each have a multi-color LED on top that lights up the push button. The devices are powered by two triple-A batteries and connect to Echo speakers via Bluetooth.
Amazon says the buttons will work with four Alexa skills when they ship on December 19 in time for the holidays, including name-that-song game "Beat the Intro" and "Fourth Down Football Trivia", with support for more sound effect and quiz games expected further down the line.
The Echo Buttons are compatible with all old and new Echo devices as well as the forthcoming Echo Spot, but they don't work with the Amazon Tap, Amazon Fire TV, or any other non-Echo device.
