Califone's Children's Headphones feature shatter-resistant earcups with leatherette cushions to eliminate exterior noise. The internal speakers have slotted baffles to prevent damage and each set has adjustable volume control. The lengthy cord has a Mac- and PC-compatible plug set at a right angle to reduce accidental pull-out. The 12-packs have a rugged plastic case with a handle and snap closures so you can easily carry and store your headphones.
