Pyle PDWM100 Dual Function Wireless/Wired Microphone System
It just happened to be a losing one, for me.  I've never heard such muddy audio in my life. I've only tested the wireless functionality, as I don't need another wired mic. I would not recommend this, to anyone, ever.   It's possible that some of these units don't make you sound like you're speaking through three feet of wet burlap, but it's not worth the gamble. Avoid.
