Acase has introduced a new Bluetooth speaker that lets you enjoy a light show as you listen to your music. The Black Diamond 3 speaker has two 3W speakers inside, and it is “the first portable Bluetooth speaker capable of mimicking music beats and rhythms through colors and movement.” It comes with a remote to control the sound levels and the light show. You can select a single color, or choose to have the speaker flow through all its possible colors. The Black Diamond 3 can connect wirelessly to Bluetooth-enabled devices, or you can connect with an audio cable. It’s $120.00 at Amazon.com.
