The Deluxe Series of stereo and monaural headphones are longstanding teacher favorites (and student-tested) for literacy and language learning activities, computer-related classes classrooms and libraries.
Califone understands equipment that's used repeatedly in classroom learning needs to be made to a higher standard. Safety features begin with slotted earcup baffles on all 2924 headphones protect the internal speakers against accidental perforation by sharp objects such as an unfolded paper clip or scissors. Noise-reducing earcups help hearing safety by resting around students' ears (not in them) to provide maximum protection against external noise, minimizing distractions so students won't increase the volume to hear the content. The rugged ABS plastic construction won't shatter (unlike materials used in consumer electronics items) into potentially dangerous shards and withstand the rigors of daily use.
The entry point of the 6' straight cord into the earcup is reinforced against accidental pull-out and is permanently attached on the stereo model (sold separately). The 1/4” plug on the monaural models connects the headphones with cassette player/recorders and can be used with jackboxes for group listening center activities.
