Amazon Echo is a hands-free smart speaker that connects to Alexa, a cloud based assistant designed to listen to your voice and help you by playing music, setting alarms, controlling smart home devices, managing to-do lists, making calls as well as checking the calendar, weather, traffic, sports scores and more. It features a 2.5" down-firing woofer with a 0.6" tweeter for crisp vocals and dynamic bass throughout the room and utilises far-field voice recognition so Alexa will be able to hear you even within noisy environments. To wake Echo simply say the wake word 'Alexa' and the Echo will light up and respond to your request.
