Shure WH20XLR Dynamic Headset Microphone



Product Description

The Shure WH20 Dynamic Headset Microphone is rugged, lightweight, and provides high quality voice pickup. The Shure WH20 microphone fits securely for active microphone users, such as aerobics instructors and musicians, with low visibility for stage appearances.

Shure WH20 Dynamic Headset Microphone Features:

  • Lightweight wireframe and elastic headband adjust for a secure, comfortable fit
  • Extra-strong, small-diameter attached microphone cable resists breakage
  • Collapsible microphone boom for easy storage and transportation
  • Smooth, natural frequency response comparable to high-quality dynamic hand-held vocal microphones
  • High input clipping level eliminates overload distortion
  • Reliable at temperature and humidity extremes
  • Supplied 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.
