Wireless audio streaming and portability are combined in the Bose SoundLink Micro Bluetooth Speaker in midnight blue with a smoky violet strap. This speaker pairs with devices over Bluetooth 4.2 with helpful voice prompts, enabling you to stream your favorite tunes through its 40mm driver and dual passive radiators. It can also pair with a compatible unit for Party Mode, where all speakers play the same track, or Stereo Mode, where one plays the left channel and the other plays the right channel.
