With a history of audio innovation spanning over 80 years, Shure has turned a passion for making great microphones and audio electronics into an obsession. No wonder Shure continues to set the worldwide industry standard for superior microphones and audio electronics.
The Shure WH20 is a rugged, lightweight, dynamic headset microphone that provides high-quality voice pickup. It fits securely for active microphone users, such as aerobics instructors and musicians, with low visibility for stage appearances.
The cardioid (unidirectional) pickup pattern provides greater gain-before-feedback and isolation from ambient noise and other unwanted sound sources.

Place the headset wireframe around the head so that the wireframe and elastic band are horizontal across the back of the head and the ends of the wireframe fit over and in front of the ears. Position the elastic headband either above or below the wireframe to provide the greatest comfort and stability. The white “SHURE” should face outward.
IMPORTANT: For maximum gain before feedback, position the gooseneck so that the microphone grille (silver side) is within 25 mm (1 inch) of the right corner of the mouth. Do NOT position it directly in front of the mouth.
If the headset feels loose or uncomfortable, carefully bend the sides of the wireframe to make it tighter or looser (Figure A). The angle of the wireframe earpieces may also need adjustment (Figure B).
Adjust the tension of the elastic headband across the back of the head by sliding it up or down the ends of the wireframe.
