The Shure Model WH20 is a rugged, light-weight, cardioid dynamic headset microphone that provides high-quality voice pickup. It fits securely for active microphone users, such as aerobics instructors and musicians, or for any voice communications application where comfort and reliability are required. An integrated elastic headband secures the headset comfortably. The headband, wireframe, and gooseneck are adjustable to accommodate any head size or shape. The WH20 is supplied with a foam windscreen and clothing clip.

The cardioid (unidirectional) pickup pattern provides greater gain-before-feedback and isolation from ambient noise and other unwanted sound sources. A carefully shaped frequency response includes a voice-frequency presence peak and a low-frequency roll-off to compensate for the proximity effect inherent in cardioid mics during close-talk operation.
