These mono headphones are longstanding teacher favorites (and student-tested) for literacy and language learning activities, computer-related classes classrooms and libraries.
Safety features begin with slotted earcup baffles to 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 and withstand the rigors of daily use.
