The USB Headset is the first headset designed specifically for school use with USB connectivity. Its unidirectional mic and ambient noise-reducing earcups are ideal for high speed internet use and applications such as distance learning, tutorials, language learning and situations requiring isolated vocalized feedback. This 10-pack of headsets is designed for AV carts, literacy groups, computers on wheels and computer labs.


  • Recessed wiring resists prying fingers for school safety
  • Fully adjustable headstrap, earcups and headstrap made with rugged ABS plastic for durability in high-use settings
  • Permanently attached cord with reinforced connection resists accidental pull out for classroom safety
  • 10’ straight cord won’t tangle with other wires and is lengthy enough to reach rear computer ports
  • Backwards-compatible USB 2.0 plug ideal for high speed internet use, delivers a more balanced sound distribution and eliminates the need for a sound card for “plug and play” performance (meaning Windows and Mac compatibility)
  • Accessible in-line volume and mute control, mic on/off switch
  • Unidirectional electret mic with flexible gooseneck and built-in wind screen reduces recording of unintended sounds
  • Noise-reducing earcup lowers ambient noise so volume does not need to be as high - recommended by the American Speech-Language-Hearing Association for hearing safety
  • Foam-lined storage case
      -  One year warranty for school use - unlike headsets purchased at consumer electronics stores whose warranties would be voided if used in schools
