A wired headset is a set of headphones attached to a microphone and connected to either a telephone or a computer using a wire connection. The connection is usually made via a headphone jack or a USB plug. A wired headset allows the user to both listen and speak using only one piece of equipment. In some instances, the headphones and microphone attach to the electronic device using a single connection, while some wired headsets must use separate wires for the two components. A wired headset can be worn either over the head, around the back of the neck, or looped around the ears, much like the variety of headphones that exist on the market. There is often confusion surrounding the function of two devices. The major difference between headphones and headsets is that, whereas headphones are meant for listening to audio, headsets are designed for two-way communication.
