Query: Unbelievable piece of JUNK!!!

I received this and immediately found that the wireless mic section had very low output, not much above speaking volume and thus useless. I plugged in a mic to test the wired section which worked okay, not super-loud but sufficient for my purposes. I thought maybe it needed a charge but found that, when plugged in, the LED charging light never came on. I called Pyle in Brooklyn and they said I could return it at my cost and they'd take a look. I then contacted Amazon and was pleased to see that they would pay for its return and send me a replacement. But when I got ready to re-pack it I found that the mic cord I'd plugged in could not be removed from the jack--somehow locked in! I call Pyle and they were of no help at all, so I'm now sending back this unit (with my mic cord still plugged into it) for a REFUND. I sure hope someone at Amazon returns my mic cord as I requested...
