Summarize this article in one sentence.
Depending on the type of headset you have, you will see one or more of the following wires: 3.5 mm audio out - This is the standard audio-out plug-in that you see on headphones and speaker systems. 3.5 mm connectors plug into headphone ports, and are usually green in color. Typically, 3.5 mm audio-out ports also support audio-in (e.g., microphones). 3.5 mm microphone - Some headsets have a separate 3.5 mm jack for audio input as well. These are usually pink. USB - USB connectors are flat and rectangular. These plug into USB ports on your computer. Laptop PCs typically have the 3.5 mm audio-out port on the left, right, or front side of the housing, while desktop PCs may have these ports on the front or back of the CPU box. Microphone ports are usually pink, while headphone ports are usually green. On laptops that don't have color-coded ports, the audio-in port will have an image of headphones next to it and the microphone input will have an image of a microphone next to it. USB port locations vary from computer to computer, but you'll normally find them near the audio ports. Plug the headset's cables into the appropriate locations on your computer. Some headsets require external power sources, though most will be powered via USB if this is the case. If you need to attach your headset to an external power source (e.g., a wall socket), do so. Once this is done, your headset is ready to be set up in Windows settings.
Check your headset's connections. Locate your computer's audio inputs. Plug your headset into your computer. Plug your headset into a power source if necessary.
