LED lights on all four sides of the mat with two modes of light show will make you feel like you are on center stage. The unit comes with two wired handheld vocal microphones and a sturdy stand for you smartphone or tablet, allowing two performers to amplify their voices as they sing along to karaoke tracks streaming from a BT-enabled device.
