I revear Shure line of MX400 gooseneck microphones which are my first choice for any live sound project I make. They are just perfect, being it for a conference room, a church or any other application that demands excellent audio, excellent feedback rejection, intense use and long life. With this capsule, R185B, I was able to revive, more than once, MX400 microphones that were there in the field for 12+ or 15+ years for a great price. They became as good as new! My customers were really grateful!
