Listening centers help teachers offer differentiated learning opportunities to smaller groups of students. The Califone series of Stereo Listening Centers tailor this learning experience to the media source already in your classroom or library. The rugged jackbox of this six position system has both 3.5mm and 1/4” plugs to connect to the most popular audio players (including computers and stereos) and offers room for expansion with spots for four extra listeners. Like the jackbox, the high quality stereo headphones are also made with rugged ABS plastic so they won't shatter. They feature ambient noise-reducing earcups which block out external noises and reduce the need to increase the volume. The headphone rack or storage case will keep everything organized until the next activity.
