Teachers understand one secret to a successful class is engaging their students. These fun animal-themed Listening First Headphones are built to do just that with playful Bear, Panda and Tiger patterns.
Purpose built with the proper age-appropriate size and weight for day care to elementary school-aged students, these unique headphones are ideal for computer-based programs (including testing to meet Common Core State Standards), literacy and language learning activities, read alongs in classrooms, library and lab settings.
Safety was a design priority for the Listening First headphones with slotted earcup baffles protecting the internal speakers against accidental perforation by sharp objects. Noise-reducing earcups rest around not in the ears to provide maximum protection against ambient noise so students won't increase the volume to hear the content. The rugged ABS plastic earcups won't shatter (unlike materials used in consumer electronics items) into potentially dangerous shards and withstand the rigors of daily use to help children remain focused on learning. The entry point of the cord into the earcup is reinforced and has in-line volume control for individual preferences. The 3.5mm stereo plug enables student listening to smartphones, tablets, computers and other audio sources. Creating a small group of differentiated learners is possible with the use of a stereo jackbox.
Optional disposable hypoallergenic cloth earpad covers (2800EC) are available for headphones in high use settings. Students and teachers tell us the covers help make the headphones feel even cooler, are comfortable to wear and help keep the earpads clean.
