Voice changer speaker with microphone will distort your voice to sound like a scary monster, a high pitched voice, or amplify your own voice! Comes with a belt clip and a self-lock strip for easy wear. There is enough wire to run from belt to mouth, and you can put the microphone inside your mask or clip to your shirt collar. Or you can run the wire down your sleeve and hold the mic in your hand. Be creative and switch between voices. Tapping the mic makes a creepy static noise, too. Requires 3 AA batteries, not included.
