Originally developed in 1910 at Stanford University, interest in headsets did not expand until after WWI, when the U.S. Army purchased a handful of them for pilots. Headsets are headphones that have been combined with a microphone. There are two variations: single or dual ear. The device works just like a speakerphone, but with better call quality.
A hands-free method of communication, headsets increase operator efficiency and productivity. Without having to bend the neck to hold a receiver, they can also make things a little easier on the neck and shoulder muscles. With hundreds of models to choose from, there is something to fit every call center and every budget.
