The Shure R189 mini-shotgun mic cartridge threads onto all Microflex® (MX) gooseneck and overhead mics, including Microflex Wireless and Microflex Complete. The narrow pickup pattern rejects ambient noise and prevents feedback in rooms with sound reinforcement, making it an ideal choice for noisy conference rooms and live presentations.
