Summary: SOUND QUALITY IS GREAT! WARNING!!!! MAKE SURE YOU GET DIFFERENT FREQUENCY MICROPHONE IF USING MORE THAN ONE. SAME FREQUENCY WIRELESS MICS GIVE OFF FEEDBACK AND STATIC. THIS MIC IS GREAT FOR LOW OR HIGHS I REALLY LIKE IT. I DO WISH I WOULD HAVE KNOW ABOUT THE FREQUENCIES DO TO THE FACT I NOW HAVE TWO OF THE SAME MIC'S. NO WORRIES I KNOW A A GREAT BACKUP IF NEEDED.
Summary: As seen above, the unit is well built - for a plastic-housed microphone, it feels almost impossible to cross-thread the battery & mic housings, so it's very solidly built, with good heft. However, if the wireless receiver is on, but you turn off the microphone, there is a distinct (and rather loud) feedback output, which is quite disturbing.
