The K-4M adds a multimedia version to our wildly successful K-4 line of educational headphones. The entire K-4 series is designed to meet the needs of small children. Most educational headphones droop when placed on their heads due to such a dramatic difference in size. K-4’s are sized for proper fit and built to be tough enough to survive a year in the classroom. Shared headphones pose a significant sanitary risk, exposing children to viruses bacteria and parasites when the headphones are passed from one child to another in a short time frame – i.e. the switching of classes. SchoolPHONES are a KID/Teacher friendly solution to the growing need to use headphones in the classroom.
