It’s a portable party with the SuperSound Karaoke™ machine! Stream your own music through Bluetooth® wireless technology or tune into the FM radio. Sing along to your favorite songs! Keep the vocals, turn them down, or take them out completely to let your voice shine. Add an echo, create a harmony, or make your voice sound high, low or like a robot. Try some vocal challenges with the Vocal Coach, then pick your song and sing to a cheering crowd. Create an epic party atmosphere with multicolored light projection. Just add a friend to double the fun! There’s a jack for a second mic (not included) with separate voice controls. Turn up the tunes, it’s party time! Intended for ages 14+ years. Requires 6 AA batteries. Batteries included for demo purposes only. New batteries recommended for regular use.
