MadBoy AERO Wireless Bluetooth Karaoke system

You can send music from any smart device via bluetooth wirelessly to the mixer while singing to wireless microphones. So playing music from Youtube, for example, is very easy. Of course, you can also connect any traditional karaoke player to the mixer with cables. The only wires you should connect are the power and speaker cables. This means that the operation is almost cordless. Can't there be an easier sound system than this?
