Headset

A headset is a headphone with a microphone. People can listen to sound with headphone and can record sound with a microphone. A headset is easy to use because it can be used without hands, just like a telephone. A person only needs to put the headset on his/her head and then can talk with a mic. Many people use headsets at the computer so they can converse and type easily. Headsets normally have only one speaker like a telephone, but also can be made with speakers for both ears.
