Students learn at their own pace and the Wireless Classroom Listening System allows you to teach up to 3 language groups at once. Simply choose a lesson per color-coded system. Each colored transmitter broadcasts the appropriate audio lesson on the correct frequency as its coordinating headphones.
Yellow system transmits at 72.100 MHz, blue system 72.500, green 72.900. Plus, any students wearing the colored headphones within 100 feet of the matching transmitter can hear the lesson, which means you can assign as many students as you have headphones.
Each transmitter also features a 1/4" mic input so you can communicate with your students over the sound of the lesson. The 1/4" audio input means you can connect any media source: computers, media players, and more. Headphones are ruggedly built to withstand the rigors of today’s classroom, the external casing is made with rugged ABS plastic -- the same material used in football helmets! Includes 4 yellow headphones, 1 yellow audio transmitter, 1 headphone charger with AC plug, 1 adapter cable to connect your audio source.
