I use the Live Wire cables for my main singer microphone, and have never had a failure. But with as much audio equipment as I have, I wanted plenty of cables. Early on, I heard someone say, "Imagine how many cables you need, then double it. And you still won't have enough."

That is eighteen 20' mic cables. I put several on a hose reel for easy winding, and those are what I use for connecting powered speakers. I also use them for the extra singer mics and the DJ mic.
They are actually quite good, and I don't mind using them handheld. They lay pretty flat, and I haven't had one go on me yet.
