To help you further understand why this is the case, we’ll discuss how the different PC audio ports work and why single-plug headsets won’t work on them. Sadly, that’s how it goes when using headsets on older PCs with multiple audio ports.

But what happens when you don’t have one? Unfortunately, that means your PC either won’t pick up your mic or playback audio. Usually, using an audio splitter will solve this problem. Many still prefer the simplicity of wired headsets, especially with the plug-and-play setup! However, things can get complicated when your headset only has a single plug, and your PC has two audio ports for input and output. We explain why using single-plug headsets on PCs requires a splitter and what you can do if you don’t have one. Purchases made via our links may earn us a commission.
