The Joyo MW-1 can take any dynamic wired microphone and turn it into a wireless microphone for small stage performers, power-point presenters and karaoke stars (microphone not included).   Four switchable channels means that you can use up to four wireless units at a time. 

This set includes (1) XLR wireless transmitter, (1) XLR Wireless receiver, (1) USB Charging cable to charge both transmitter and receiver at the same time.

It does NOT provide phantom power, so condenser microphones are not compatible.
