What would that look like? Can you provide a couple of specific pieces of hardware examples?

Any USB audio interface such as those made by Focusrite, MOTU and many others. That plugs into your computer.

Any XLR mic, such as the Shure models mentioned in the article. That plugs into the audio interface.

Any (analog+wired) headphones (you'll have my MDR-7506s over my dead body). These plug into the audio interface.

Done.
