We want you to know:
Echo Sub must be paired with a compatible Echo device. Echo Sub is optimized for Echo (2nd Gen) and Echo Plus (2nd Gen). Currently, stereo pairing, speaker groups, and multi-room music only support music playback over your wireless network, and do not support Bluetooth, 3.5mm AUX in, or TV/video connections. Some Echo devices support different stereo and subwoofer configurations. Learn more.
