Dynamic or condenser: decide by your room
A dynamic microphone hears mostly what is close to it, which suits an ordinary room with a fan, a keyboard and hard walls. Samson, for example, describes its dynamic Q2U as less sensitive to background noise and suited to untreated rooms.
A condenser microphone is more sensitive and picks up more of the room with your voice. It rewards a quiet, soft-furnished room. The USB condensers here take their power from USB; an XLR condenser would need 48 V phantom power from the interface.
Whichever you choose, set the level with the microphone test: its room-noise reading shows how loud the room is between your words.
Streaming ASMR? Whispers and taps need a stereo or very quiet condenser and none of the voice filters: ASMR microphone for streaming.
USB, XLR or both
A USB microphone contains its own converter and plugs straight into the computer. An XLR microphone sends an analog signal that needs an audio interface or mixer with a microphone preamp, and an XLR cable; the interface then connects to the computer over USB. A hybrid does both, so you can start on USB and move to an interface without replacing the microphone.
The interface matters more for some microphones than others. Shure says the SM7B needs more than 60 dB of gain, more than most entry-level preamps give, so check the interface’s gain before you buy either. The setup builder checks that for you, and USB versus XLR explains the whole chain.
Put it close to your mouth
Distance changes how you sound. Shure’s guide puts the SM7B 1 to 6 inches from the mouth to keep out off-axis noise, and says moving closer adds bass. A microphone at arm’s length on the desk hears more of the room and the keyboard. A boom arm lets you keep it close without it sitting in your camera shot; check that the arm fits the microphone’s thread, which each model’s page lists.
What to budget for besides the microphone
The site does not list prices, but it can tell you what else each model needs. Count these before you choose:
- An interface and an XLR cable for an XLR microphone. For a hybrid on USB, neither.
- A stand or boom arm when none is in the box: the MV7+, PodMic USB, SM7B and Wave DX come without one.
- The right cable for your computer’s ports. Several models come with USB-C at both ends; a computer with only USB-A ports needs a different cable.
- Headphones to hear yourself through the microphone’s headphone socket, which every USB model here has.
Each product page lists these under What else you need, worked out from the maker’s own box contents.
Check it before you go live
Open the microphone test and speak at your normal volume, then your loudest. Its meter uses OBS’s own zones: speech should sit in the upper yellow and reach the start of the red, never 0 dBFS. Then record ten seconds in OBS and listen back. If OBS shows no level at all, follow microphone not working in OBS.
Questions
What is the best budget microphone for streaming? The site does not track prices, so it cannot rank by cost. What keeps the total down is buying nothing extra: a microphone whose box already holds the stand and cables, such as the Samson Q2U, whose box has a USB cable, an XLR cable and a tripod stand, needs nothing more to start.
Do I need an audio interface for streaming? Only for an XLR microphone. A USB microphone, or a hybrid used over USB, plugs straight into the computer. The audio interface guide matches the current interfaces to each situation.
Is the Shure SM7B good for streaming? Shure lists radio announcing and talk shows among its uses, and it suits a close, speech-focused setup. It is XLR only and needs more than 60 dB of preamp gain, so budget for the interface and an arm as well.
Which microphone is best for gaming streams? The same rule applies: a dynamic microphone close to your mouth keeps keyboard and fan noise down. The MV6, MV7+, Q2U, PodMic USB and Seiren V3 Pro are dynamic.

A plug-in USB dynamic microphone for voice
Shure MV6
Use it directly over USB. Choose an XLR or hybrid microphone instead if you intend to move the same mic onto a standalone analog mixer.
Connections & full profile →USB now, an XLR interface later
Shure MV7+
Use USB for the microphone’s DSP and headphone features. On XLR, plan processing and monitoring at the interface; those USB features do not follow the analog cable.
Connections & full profile →A USB and XLR dynamic microphone with its cables and a desk stand in the box
Samson Q2U
Its USB audio is 16-bit at 44.1 or 48 kHz. On the XLR route it needs an interface with a microphone preamp.
Connections & full profile →View at Samson ↗A USB and XLR microphone: a computer now, a mixer later
RØDE PodMic USB (Black)
Choose a mount that supports the microphone’s documented weight. Use USB for its onboard processing, or plan processing and monitoring separately on the XLR route.
Connections & full profile →A dynamic hybrid microphone for direct USB or an XLR interface
Razer Seiren V3 Pro
Use USB when you want the microphone’s software processing. On XLR, add an interface and do the processing there; the USB features don’t carry over to the XLR output.
Connections & full profile →A broadcast dynamic microphone for a close, speech-focused voice
Shure SM7B
It needs more gain than most entry-level interfaces give: Shure asks for a preamp with more than 60 dB of gain, or an inline booster. Choose the interface before the microphone.
Connections & full profile →View at Shure ↗An XLR voice microphone for use with an audio interface
Elgato Wave DX
Add an XLR cable and an interface with a microphone preamp. A USB cable or passive XLR adapter alone cannot connect this microphone to the computer.
Connections & full profile →A USB condenser for a controlled recording space
RØDE NT-USB+
Use the direct USB route and place the microphone close enough for a clear voice before treating room reflections with processing. Choose another microphone if an XLR mixer connection is required.
Connections & full profile →A USB microphone with Elgato’s Wave Link software
Elgato Wave:3 MK.2
Choose the MK.2 as your audio device and set up its processing before adding it to OBS; guides for the first Wave:3 describe different processing.
Connections & full profile →A plug-in USB microphone for a simple desk
Elgato Wave Neo
Choose it for one direct USB speaking position and use its headphone jack to monitor your voice. For two separately controlled speakers, plan two microphones and an interface with two inputs.
Connections & full profile →A USB condenser microphone with four pickup patterns, tap-to-mute and a shock mount
HyperX QuadCast 2 S
For one voice, use the cardioid pattern and keep it close: the omnidirectional and stereo patterns take in the whole room by design.
