USB vs XLR: Which Should You Choose?
The first decision is connection type. USB microphones plug directly into your PC with no extra equipment needed: perfect for beginners and streamers who want simplicity. XLR microphones require an audio interface but offer better sound quality, upgrade flexibility, and professional-level control.
Best USB Microphones for Streaming
USB mics are the fastest path to dramatically better audio. Most streamers on Twitch, YouTube, and Kick use USB condenser microphones.
- Excellent sound quality for USB
- 4 polar patterns: very versatile
- Built-in headphone monitoring
- Blue VO!CE effects software
- Large and heavy
- Picks up keyboard noise easily (use cardioid)
- Pricier than entry-level options
- RGB lighting looks great on stream
- Built-in shock mount reduces desk rumble
- Tap-to-mute is genuinely useful
- RGB can be distracting
- Slightly coloured sound (some prefer neutral)
- Clipguard prevents distortion
- Wave Link virtual mixer is excellent
- Clean, flat frequency response
- Cardioid only (no pattern switching)
- Pricier than similarly-specced rivals
- Chroma RGB integration with other Razer gear
- Tap-to-mute sensor
- Supercardioid picks up less room noise
- Razer Synapse required for full features
- No headphone monitoring port
Budget USB Option: FIFINE K678
If you're just starting out and don't want to spend more than $50, the FIFINE K678 (~$40) is genuinely good for the money. USB-C connection, cardioid pattern, and a built-in headphone jack. It won't match the Blue Yeti but it's a massive step up from any headset mic.
Best XLR Microphones for Streaming
XLR microphones require an audio interface but offer better noise floor and more upgrade flexibility. The Focusrite Scarlett Solo (~$120) or Solo 4th Gen is the standard entry-level interface recommendation.
- Legendary broadcast sound
- Built-in preamp solves SM7B gain issue
- Excellent noise rejection
- Industry standard: holds value well
- Expensive (mic + interface = $500+)
- Dynamic mic: less sensitive than condensers
- Excellent sound for the price
- Wide, detailed frequency response
- Well-built: lasts years
- Picks up room reflections (needs acoustic treatment)
- Requires interface and XLR cable
Buyer's Guide: What to Look For
Polar Pattern
For streaming and gaming, cardioid is almost always the right choice. Cardioid mics pick up sound primarily from the front and reject sound from the sides and rear: which means less keyboard noise, less PC fan noise, and less room echo reaching your stream.
Dynamic vs Condenser
Dynamic mics (like the SM7B) are less sensitive and work better in untreated rooms with background noise. Condenser mics (like the AT2020 and Blue Yeti) are more sensitive and pick up more detail: great for quiet rooms but they also pick up every keyboard click and fan hum.
Boom Arm vs Desk Stand
A boom arm is essential for consistent positioning and to keep the mic off your desk (reducing vibration noise). The Rode PSA1+ (~$99) and Elgato Wave Mic Arm (~$100) are the most popular choices. Don't rest your mic directly on your desk: vibration from typing and mouse clicks will be audible.
Setup Tips for Better Audio
- Position matters: Keep the mic 15–20cm from your mouth, slightly off-axis to reduce plosives (p and b sounds)
- Use a pop filter: A foam windscreen or pop shield prevents plosive sounds from distorting
- Treat your room: Heavy curtains, bookshelves, and soft furnishings reduce echo. You don't need acoustic panels
- Gate your mic in OBS: A noise gate filter removes background noise between sentences. Set threshold just above your background noise floor
- Use a noise suppressor: NVIDIA RTX Voice or Krisp.ai can remove keyboard and fan noise in real-time with AI
Frequently Asked Questions
Is a USB or XLR microphone better for streaming?
For most streamers, a USB microphone is the better starting point. It requires no extra equipment, sounds excellent at $100 to $150, and is genuinely indistinguishable from XLR for most viewers. XLR becomes worthwhile when you want broadcast-level quality (Shure SM7dB), plan to expand your setup with multiple mics, or want a quieter noise floor for recording in a treated room.
What is the best streaming microphone under $150?
The Blue Yeti X at around $130 is the top recommendation. It offers four polar pattern modes, a built-in headphone monitoring jack, and excellent voice reproduction. The Elgato Wave:3 at $150 is an alternative with its Clipguard anti-clipping technology and Wave Link virtual mixer built in.
Does the Shure SM7B need a preamp?
The original SM7B requires around 60dB of clean gain, which many budget interfaces cannot provide cleanly. The newer Shure SM7dB solves this with a built-in preamp that adds up to 28dB, making it compatible with most audio interfaces including the Focusrite Scarlett Solo. If you choose an SM7B over the SM7dB, pair it with a Cloudlifter CL-1 for extra gain.
How do I reduce background noise in my stream audio?
Use a cardioid polar pattern microphone positioned close to your mouth (15 to 20cm). Apply a noise gate filter in OBS to silence the microphone between sentences. NVIDIA RTX Voice and Krisp.ai both apply real-time AI noise suppression and are very effective at removing keyboard and fan noise. Physical room treatment (heavy curtains, soft furnishings) also helps significantly.
Do I need a boom arm for streaming?
A boom arm is strongly recommended. It keeps the mic off your desk, reducing vibration from typing and mouse movements from reaching the microphone. It also makes positioning easier and keeps the mic consistently in front of your mouth. The Elgato Wave Mic Arm and Rode PSA1+ are the most popular choices among streamers.
