Connect to a Bluetooth speaker, an AirPlay device or a smart TV, tap once, and your voice fills the room. No hardware to buy, no cables, nothing to pair twice. SING KARAOKE ANYWHERE Your phone becomes the karaoke microphone. Sing over any backing track through the speaker at your party, in the backyard or on vacation, and hear yourself loud and clear with almost no delay. BE HEARD IN ANY ROOM A wireless microphone in your pocket means you can address a classroom, a wedding, a meeting or a crowd without a PA system. Speak normally; the speaker does the work. SOUND THE WAY YOU WANT Choose from 29 voice effects, from echo and reverb for singing to robot, cave and cartoon voices for fun.
