If you like your electronics with bells and whistles, the JBL PULSE Wireless Speaker that comes with an LED light show is right up your alley. At its core, the PULSE is a wireless Bluetooth stereo speaker with a 10-hour battery, high-performance drivers and a built-in bass port that will rock your world with high fidelity sound. The bells and whistles come in the form of a visual experience involving programmable LED lights that put up a light show in sync with the music being played. You can download programs and use them to reprogram the light show into something different, or even customize the colors and brightness patterns yourself. Turn off the lights in the room and let the PULSE rip to create a disco ball room in your own home.
