This pack of twelve animal-themed headphones is ideal for engaging students. Each of the four playful Bear, Panda, and Tiger headphones has an adjustable volume control for individual preferences and is built for young students with appropriately sized and rugged ABS plastic earcups. These stereo headphones are ideal for library, story-time, classroom, and computer uses. Adjustable headband comfortable for extended wear. Lengthy 6 foot straight cord with 3.5mm plug set at right angle reduces accidental pull-out. Around-ear ambient noise-reducing earcups deliver maximum protection against exterior sounds. This reduces the need to increase the volume (protecting the ears) and helps keep students on task. Replaceable leatherette ear cushions. IBM, iMac and Mac compatible. One year warranty for school use - unlike headphones purchased at consumer electronics stores whose warranties would be voided if used in schools.
