Califone CLS7XX Series Wireless Headphones

Califone CLS7XX Series Wireless Headphones


Califone CLS7XX Series Wireless Headphones are ideal for language learning, literacy groups, ELL and ELD applications, story-time, audio book listening, and library uses. Their 100 feet reception range from the matching color coded transmitter (which is sold separately), helps create flexible learning situations where the students do not need to be next to the media player.


  • Califone CL57XX Series Wireless Headphones are made of rugged ABS plastic earcups and headstrap for durability

  • Each colored headphone operates on its own independent frequency, three different groups can enjoy wireless learning in the same room without any interference
  • There is no limit to the number of headphones which can be added, only that
    they must match the same color-coded transmitter frequency
  • Rechargeable batteries
