With integrated wireless connectivity, voice recognition, and home automation support, the sandstone fabric 2nd-generation Amazon Echo isn't your typical wireless speaker. Equipped with dual-band Wi-Fi and a 7-microphone array, the 2nd-generation Echo connects to your home's wireless network and allows you to intuitively play music, check the weather and traffic anywhere in the US, hear sports scores, and more. Using far-field voice recognition technology, the 7 built-in microphones allow the Echo to recognize your voice from any direction in the room, even while music is playing. Bluetooth is also on-board, enabling the Echo to wirelessly pair and play audio from a variety of audio sources, such as smartphones and tablets.
