Connect to your own external music player via Bluetooth® to listen and sing-along to your favourite tracks! There are 15 built-in sing-along songs on the Singing Sounds Microphone, sing-along to all of them with or without the vocal track at the press of a button! For extra fun, apply a funny voice changing effect to see how silly you can sound! The multicoloured light on the microphone lights up with the responses and music. There's also dedicated buttons which control volume level, pause, play, previous, skip and instant applause sound effects.
