I've used this sort of a mic since around 2005. The Shure one really impressed me but we found when some singers use them and others onstage use something more conventional, the conventional mics win out. Not a problem in my rock 'n' roll band as both mics are Elvis mics but in other bands we've found a more modern mic will be louder and clearer. Within the context of using them exclusively, we probably turn up a bit more to compensate but they absolutely deliver 100%.
