Califone 2800-BL Listening First Stereo Headphones, Blue, Adjustable Headband Comfortable for Extended Wear, Specifically Sized for Young Students, Replaceable Leatherette Ear Cushions

This Listening First stereo headphone is specifically built for young students with safety as its first concern. Rugged ABS plastic earcups withstand daily use with slotted earcup baffles to prevent accidental damage from prying fingers or foreign objects.
