The echo dot is a hands free voice controlled device that can play your favorite songs, provide information, set alarm clocks, control your smart home devices like opening garage doors, fans, thermostats, sprinklers and turning off/on lights. It is very specific. It can connect to speakers and headphones through Bluetooth. It works where you would want a voice control computer around your home and can hear you well even across the room. There will be many more features added to this in the future. A link down below will help you to purchase this item or learn more.
