Great sounding mics. I use them in in my karaoke show setup for the main singer(s) mics because of the sound quality you get from them and they have proven to have great durability to be handled as much as they do over many shows and singers where people tend to be a little rougher with mics for obvious reasons. My only problem is that the power plug had the lead prongs pulled out of the body of the transformer plug ( the end that goes into the wall/electrical outlet ). which I now have to replace... but at least those are easier and cheap to find. hopefully calling support will help out which is my next step.. but overall I love the mics and would love to product test the rack mounted 4 mic version before trying another rack mounted brand. I knocked off a start only because of the issue with the quality of the plug, not the actual mics or system itself. Certainly not studio quality, but for live performance and specifically karaoke groups with rough handling?? Perfect solution at a tremendous value. For a sponsorship I'd talk these mics up all day!! lol very happy with them though completely honest..
