Amazon Echo Dot, Black

Controls lights, fans, switches, thermostats, garage doors, sprinklers, and more with compatible connected devices.
Connects to speakers or headphones through Bluetooth or 3.5 mm stereo cable to play music.
Hears you from across the room with 7 far-field microphones for hands-free control, even in noisy environments or while playing music
Includes a built-in speaker so it can work on its own as a smart alarm clock in the bedroom, an assistant in the kitchen, or anywhere you might want a voice-controlled computer
Always getting smarter and adding new features, plus thousands of skills.
Use Echo Dot to switch on the lamp before getting out of bed, turn up the thermostat while reading in your favorite chair, or dim the lights from the couch to watch a movie, all without lifting a finger...or even raising your voice.
Alexa, the brain behind Echo Dot, is built in the cloud, so it is always getting smarter.
The more you use Dot, the more it adapts to your speech patterns, vocabulary, and personal preferences. And because Echo Dot is always connected, updates are delivered automatically.
With the free Alexa App on Fire OS, Android, iOS, and desktop browsers, you can easily setup and manage your Echo Dot.
