They make horrible mics, its simple as that. I take decent care of my mics and I'm also on my 3rd one. My friend is already on his 4th wireless mic and this is less then a 2 year span. His second wireless mic broke after 92 days and it had a 90 day warranty so they wouldn't replace it. I think a miniature C4 charge goes off in the wireless mics after 90 days.
