Shure WH20QTR | 1/4in Connector Cardioid Headworn Dynamic Microphone

The Shure WH20QTR is a highly reliable, lightweight, and dynamic headset microphone crafted specifically for high-quality voice pickup. This microphone is perfect for users who need to stay active while ensuring clear audio transmission, such as aerobics instructors, vocalists, and stage performers. With its rugged construction, the WH20QTR fits snugly and securely, providing low visibility for stage appearances and a polished, professional look.

Featuring a cardioid (unidirectional) pickup pattern, the Shure WH20QTR guarantees greater gain-before-feedback and excellent isolation from ambient noise and other unwanted sounds. Its carefully contoured frequency response includes a voice-frequency presence peak and a low-frequency roll-off, which compensates for the proximity effect often experienced with cardioid microphones during close-talk operation. With these detailed refinements, the WH20QTR offers a natural, smooth frequency response that rivals high-quality dynamic hand-held vocal microphones.

Reliable under extreme temperature and humidity conditions, the Shure WH20QTR is an excellent choice for any situation demanding durable and consistent audio performance. The microphone comes equipped with an extra-strong, small-diameter attached cable that resists breakage, a collapsible boom for easy storage and transportation, and accessories like a foam windscreen and clothing clip for convenience and enhanced performance.
