A gaming headsets is a must have item for every gamer, not only as an alternative to speakers for late night gaming sessions, but also the built in microphone enables you to coordinate with teammates or taunt enemies online. Not only that, but most headphones provide better positonal order than speakers, so you're better able to judge if somebody is on your own left or right.
Wired gaming heasets connect to your PC using either an analogue 3.5mm minijack or USB cable. This means that unlike a wireless gaming headset you don't need to worry about the batteries running out at an inopportune moment, but you are tethered to your PC.
