For a solo stream, a USB microphone is usually the simpler place to start. An XLR setup makes sense when you want to choose the microphone and interface separately, connect several microphones, or use a mixer. The useful question is how you want your setup to work.
This guide compares the connections, the equipment around them and the costs you should count before buying. It is based on manufacturer documentation and setup guidance; it does not assign listening-test scores to microphones.
USB vs XLR: the practical differences
| Question | USB microphone | XLR microphone |
|---|---|---|
| How does it reach the computer? | Digital audio through the microphone’s USB connection. | Analogue audio to an interface or suitable mixer, then to the computer. |
| Where are the preamp and converter? | Built into the microphone. | In the interface or other recording hardware. |
| What should the budget include? | Microphone, suitable cable and mounting; check what is included. | Microphone, XLR cable, interface and mounting. |
| Can you monitor your voice directly? | If the model supports direct monitoring. | If the interface or mixer supports direct monitoring. |
| What changes when you upgrade? | You can keep using the complete USB microphone; changing its built-in electronics usually means changing the mic. | You can change the microphone or interface separately. |
| What about several microphones? | Check the operating system, software and device support. | Choose an interface with enough suitable microphone inputs. |
What happens between your voice and the computer?
A USB microphone puts the microphone, preamp and analogue-to-digital converter in one device. With XLR, the microphone sends an analogue signal to external recording hardware. An audio interface supplies the preamp and converter and can itself connect to your computer over USB. Seeing a USB port on the interface therefore does not make the attached XLR microphone a USB mic. Focusrite explains microphone inputs and preamps here.
The connection also does not tell you whether the microphone is dynamic or condenser. For example, RØDE lists the PodMic USB as dynamic and the NT1 5th Generation as condenser; both offer USB and XLR. These are separate characteristics to check when comparing models.
Will XLR make your stream sound better?
Judge the complete recording chain. The microphone, placement, room, gain and processing all matter. RØDE’s explanation of the NT1’s two outputs shows why: USB uses its internal preamp and converter, while XLR uses external hardware. The equipment and processing settings can change the result.
If your recording is full of room echo, start with microphone placement and the room. Shure explains the balance between direct speech and reflected sound. Moving the microphone into a sensible speaking position can be more useful than buying another connection type. Record your normal speaking voice and listen back before deciding what needs changing.
Compare the whole setup cost
For USB, check whether the price includes a usable stand or arm, the correct cable and any pop filter you need. For XLR, add an interface with a microphone input, an XLR cable and mounting. Headphones may be another purchase with either setup. A cheap microphone can become an expensive shopping basket once you add the missing pieces.
If you already own an interface, count that differently from buying one from scratch. For several speakers, count suitable microphone inputs rather than the total number of sockets. Before ordering, check the interface’s connections, gain range and supported operating systems against the microphone you intend to use.
Check monitoring before worrying about latency
Direct monitoring lets you hear the microphone through the hardware without waiting for the signal to travel through your recording software. Focusrite describes this as a near-zero-latency monitoring path. USB microphones can also provide this feature; the PodMic USB is one documented example. Check the specific device rather than assuming every USB or XLR setup behaves the same way.
If you hear yourself twice, check whether hardware monitoring and delayed software monitoring are both active. Direct monitoring does not remove the delay between broadcasting and a viewer receiving the stream. For the practical recording and filter steps, continue with our Twitch microphone setup guide.
Which setup fits your stream?
- One voice, one computer, few extra boxes: start by comparing USB microphones with suitable mounting and, if you want it, direct monitoring.
- An interface already on your desk: compare compatible XLR microphones and check the input and gain requirements.
- Several people in the same room: an interface with enough microphone inputs is worth considering. Multiple USB microphones can work too: Apple documents Aggregate Devices on macOS. Check your own software and operating system before buying.
- USB now, an interface later: a model with both connections gives you those options. Check which controls and processing features work in each mode.
An example with both connections
The RØDE PodMic USB datasheet lists USB-C, XLR and a headphone output with direct monitoring. That makes it a useful example of a microphone you can connect directly to a computer or use with an interface. Check the exact PodMic USB model, included accessories and mounting before buying.

Questions before you buy
Do all XLR microphones need 48V phantom power?
Check the microphone’s manual. Many XLR condenser microphones need phantom power, while ordinary passive dynamic microphones do not. Active electronics can change that requirement. Focusrite explains the differences and recommends switching phantom power off before connecting or disconnecting equipment.
Can a USB microphone be enough for a serious stream?
Yes. Choose a microphone whose features fit the way you record, then work on placement, levels and monitoring. XLR gives you more choice over the separate hardware; USB can provide a convenient complete device.
What should I do after choosing?
Make a short recording at your desk, including normal speech, a louder sentence and a pause. Listen for distortion, distracting room sound and keyboard noise. Then use our OBS Studio setup guide to finish the software side.
