Long-lasting headphones with safety features such as recessed wiring to avoid curious little fingers. Appropriately sized, lightweight and comfortable for beginning readers. The key to listening centers is the jackbox, the distribution point to the headphones. Califone gives more attention to this eight-position jackbox with features such as silver-plated contact points for a solid connection and moisture resistance, individual volume controls, and rugged ABS plastic housing for durability. Two predrilled holes to permanently affix to a surface.
