Concept Learning Educational Wireless Infrared Headphones Silver [HH00514]

Concept Learning Educational Wireless Infrared Headphones

Concept Learning Educational Wireless Infared Stereo/Mono Headphones in Silver. The Concept Learning multi-purpose Infra-red headphones can be used for monaural language-based activities or with the flip of a switch, also for stereo computer-based programs. The wireless headphone receives the audio signal not only with media players equipped with a built-in infrared transmitter, but also from a classroom computer (Mac or Windows compatible) with a connected USB transmitter and extender (sold separately).

The headphone has an adjustable headband with ambient noise-reducing earcups to help block out external distractions and keep students on task. The ambient noise-reducing earcups of the Concept Learning wireless headphones lowers external noise so volume does not need to be as high, as recommended by audiologists for hearing safety.

There is no limit to the number of listeners so long as they're within the 6m transmission range with a clear line of sight between the headphone and transmitter.
