you DO NOT get noise cancellation with these. DONT BUY THESE LOOK FOR SOMETHING ELSE BUT DEFFO NOT COMMAND PRODUCTS! I teach line dance and use mics from multiple venues and DJs and this one was recommended by a DJ friend as a "good, but not great" mic to try. It also looks more expensive!

I contacted Flexz to get replacements and they required pictures, proof of purchase, etc etc that has no validation at this point anyway, when I provided them, they wouldnt respond. Generell lässt sich aber sagen, dass die Telefonie wirklich besser ist, als die bisher getesteten Produkte von Zolo bzw.

Well seeUpdate: Flip flops are my primary footwear. Like I said before, when it works, it works fine.
