While sized for the PreK-4th grade students, the streamlined design of this rugged stereo headphone makes it accessible to older students with a fit that's "just right". Generously padded headband and ear cushions makes for comfortable listening. Its passive noise reducing earcups fit around, not on, ears to better block external sounds and help students stay focused on the task at hand. The audio playback is calibrated to enhance the tonal range of the human voice in language learning. Inline volume controls ideal for use in assessments. Compatible with Chromebooks, iPads, iPhones, Galaxy, Surface, laptops, desktops, and Macs. Universal 3.5mm plug with 6' straight cord. 3-year warranty.
