Since it doesn't take an expert to set it up, the Vonyx WM522 wireless microphone system is a fuss-free solution for house parties and Friday night karaoke. This simple system runs on fixed frequencies within the VHF frequency band and includes two handheld microphones that feature a built-in mute function and can be used simultaneously. Simply pop in two AA batteries per microphone and they're good to go. The dual receiver, meanwhile, features individual volume controls, a handy little display and a jack output for connecting to an amplifier.
