I had the distinct privilege of utilizing this microphone during a live performance. As a vocalist, it does not get much better than to hear your own voice reproduced exactly as you hear it in your mind; and that is exactly what the 87A provides. I, personally, consider this microphone to be Shure's masterpiece. Every nuance is picked up just as it is put out. Issues with muddiness, save for a vocalist's natural sound, vanish instantly.
