Teachers have to buy each student in the classroom a set of headphones so they can work individually on their own devices. Not only is this costly, but it’s also very inconvenient too, as you have to have the loudspeaker on for students to hear what’s being taught in class. The Audio Splitter is an extremely convenient accessory, particularly for classroom settings, taking one audio cord and splitting the connection to two different devices. This allows students to work together and keeps educators from having to use too many devices at the same time. The long 18” cord can easily stretch around computers for a secure connection and the 3.5mm outlet allows for connections with multiple different devices. Features: Long 18” cord 3.5mm headphone outlet 2-into-1 stereo connection Warranty: For use in school
