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 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. The 3.5 mm 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.
