Put your phone or tablet next to the speakers and play some music.
The lights blink to the real rhythm of the music currently played on your sound system.
You can choose single or 3 lamp mode. The lamps react to low tones (bass), treble and mid tones. Invite friends with their tablets / phones, on each one choose a different lamp for better effects.
