The iDance Groove 508X is a portable 500-watt battery speaker with 2 wireless microphones and a built-in light show. You stream music wirelessly via Bluetooth or play music via the radio, from a USB stick or SD card. This means that you always connect a suitable sound source to the speaker. You sing karaoke with the 2 included wireless microphones. From a bad boy band to happy hardcore, you decide for yourself which music to sing along with. With the built-in mixer you ensure a smooth transition between 2 numbers. This allows you to mix music seamlessly, just like a DJ. When you use the speaker outdoors, you don't have to lift it, because it has wheels.
