This cool LED bar provides a visual representation of ambient sounds. No wiring required, as it has a built-in microphone to detect the sound. 2 light bars included.

This LED bar has 32 separate color LEDs that can be displayed in 8 different options as an audiometer. There are 60 different color options. The color settings can be selected with a button on the back of the bar. This is also where the 5-volt USB port for charging is located. The cable is, of course, included.
