USB headsets are available in three basic versions. Headsets with two earpieces and a microphone on a bracket provide stereo playback and have a high audio quality. In addition, they limit interference from ambient noise. The ear cups can be attached to a headband or neckband.
USB headsets with a microphone and one earpiece on a bracket allow users to perceive the surrounding noise and are a little easier to wear, because they are lighter. Playback is limited to mono sound.
USB headsets with in-ear headphones are also available. These devices are very light and unobtrusive. They have good sound quality and are equipped with an integrated microphone in the cable.
