Califone 4-PERSON WIRELESS LEARNING SYSTEM CLS725-4 - headphones

The wireless headphones are 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. Since each colored headphone operates on its own independent frequency, three different groups can enjoy wireless learning in the same room without any interference.
