About Califone CLS729-4

Helping create flexible learning situations where the students do not need to be next to the media player with its reception range of 100' from the matching color-coded transmitter, the Califone CLS729-4 4-Person Wireless Headphone Learning System is ideal for language learning, literacy groups, ELL/ELD applications, story-time, audio book listening and library uses. There is no limit to the number of headphones which can be added, only that they must match the same color-coded transmitter frequency. They have ambient noise-reducing rugged ABS plastic earcups and headstrap that diminish external distractions and add durability. It is powered by rechargeable batteries. This unit has a frequency of 72.900 MHz and has a green color-code.

This system includes four wireless headphones, a matching color-coded VHF transmitter that plugs into any audio source (MP3 player, computer, multimedia player, VCR/CD/DVD player, or television monitor), all necessary charging cables and an AC adapter.
