WBH53 Headworn Vocal Microphone

The WBH53 (wireless version of the Beta 53) is a fully adjustable omnidirectional condenser microphone, designed for applications where unconspicuous appearance and incredible sound quality are required. It's lightweight, adjustable, modular headband, flexible wireframe and soft earpieces provide a comfortable fit while still allowing the Beta 53 to be positioned as close to the left or right corner of the mouth as possible, assuring maximum voice pickup.

  • WBH53B - Black, 5-foot (1.5 m) attached cable with 4-pin mini connector (TA4F), foam windscreen, clothing clip, carrying case
     
  • WBH53T - Tan, 5-foot (1.5 m) attached cable with 4-pin mini connector (TA4F), foam windscreen, clothing clip, carrying case

 

Beta quality, sensitivity and consistency in a nearly invisible, ultra-thin design. Omni, condenser.

The Beta 53 microphone itself features an extended frequency response and high SPL handling ability. The Beta 53 is uniquely designed to provide the sound quality and performance consistency required for environments such as professional theater, event production, trade shows or seminars - the best sound with minimal visibility.

 

  • Comfortable, latex-free Dynaflex® earforms that hide behind the ears

  • Ultra-thin detachable microphone boom mount for right or left positioning
  • Interchangeable frequency response caps (mild or high, two pieces each)
  • Two foam windscreens included
  • Clothing clip for securing cable
  • Corrosion resistant
  • Easy to clean
  • Durable carrying case for protective storage
  • Available with either TA4F connectors or tinned leads (no connector) for full wireless system compatibility
