A USB microphone is the easiest upgrade for voice chat, streaming and recording, because it plugs straight into your PC with no extra gear. These are the things that change how it sounds.
USB or XLR
A USB microphone has the converter built in, so it works with a single cable. An XLR microphone needs an audio interface or mixer, which costs more but lets you upgrade each part separately. Under $100, USB is the simple and sensible route.
Condenser or dynamic
A condenser microphone is sensitive and detailed, which is great in a quiet room but also picks up keyboard clicks, fans and room echo. A dynamic microphone is less sensitive and rejects more background noise, which helps in an untreated room. If your room is noisy, a dynamic model, or a condenser used close to your mouth, will give cleaner results.
Pickup pattern
Most microphones for one person use a cardioid pattern, which picks up what is in front and rejects the sides and back. Some offer extra patterns such as omnidirectional, bidirectional or stereo, which are useful for interviews or for recording several people around one microphone.
Features that are worth having
- Headphone jack with direct monitoring lets you hear yourself with no delay.
- Mute button that you can reach quickly during a stream.
- Gain control on the microphone itself, so you can set levels before touching software.
- Stand and mount. A boom arm and shock mount reduce desk bumps and free up space.
Placement matters more than price
Place the microphone roughly a hand-width or a little more from your mouth and slightly off to one side, so breath sounds do not blast the capsule. A pop filter helps. Speaking at a steady distance gives a steadier volume than any software fix.
Clean it up in software
Streaming programs such as OBS include filters for noise suppression, a noise gate and a compressor. Record a short test and listen with headphones before you go live.
