Everyone’s desk and setup requirements are different, so a mic must perform well under a handful of different scenarios. Suppose a microphone sounds better than all the rest combined but only when it’s on a suspended mic stand with a shock mount positioned precisely six inches away from your mouth. In that case, it’s not necessarily a reliable option to recommend.
Saying that, however, there are some valuable bits you might want to pick up if you're looking to clear away clutter or build a more professional setup.
A boom arm certainly helps achieve both of those things. These almost always clip onto the side of your desk and are super handy to keep your mic close to hand while off your desk, saving precious real estate.
While a pop filter will help reduce plosives, the sound of air escaping violently from your mouth and towards the mic, from making their way over to airwaves to your listeners' unfortunate ear holes. It'll also stop your microphone from getting grubby when you're up-close and sounding sibilants.
A shock mount is perhaps the least necessary of the lot, at least for gaming. These prevent vibrations from traveling through your microphone stand or boom arm and into the microphone, which can come through as rustle, thuds, or otherwise unwanted noise. Certainly a must-have for music studios, unless you are one to slam your way through a match of Apex Legends, you might be okay without.
