This is for a rock jam karaoke machine. Particularly for kids. Comes with two microphones and allows you to play your own music through it either from a device such as a phone via Bluetooth or a cable connected device. Has some voice effects you can apply which I’m sure the kids will love and generates a light show on the front in response to the music. Nice condition both the unit and the microphones it doesn’t have a power cable with it, but it’s a standard 5 V DC plug. I used a generic multi adapter that I have to test it.
