Let your vocals shine with the kid-size Sing It Out Karaoke Microphone™. Sing along to the 15 included songs, then press a button to drop out the vocals when you’re ready to sing alone. Children's favorites like "Twinkle, Twinkle Little Star" and "One, Two, Buckle My Shoe" make it easy for everyone to sing along to familiar songs. Party lights on the mic add pizzazz to your performance as they change color and flash along to the music. Use Bluetooth wireless technology to play your own music. Hit the voice-changer button and try out five silly voice effects like reverb, echo or robot sounds to impress your audience. Hear the cheers as the microphone adds sounds and encouraging phrases. Requires three AAA batteries. Intended for ages 2–5 years.
