XLR Microphone Comparison for Podcasters: Shure, Rode, and Electro-Voice
TL;DR: RØDE describes the PodMic as a speech-focused XLR mic with an internal pop filter and shock mount (RØDE). The Shure SM7B adds electromagnetic hum shielding and switchable response settings, and Shure says it needs more gain than most entry-level or mid-tier preamps deliver (Shure SM7B guide). Electro-Voice says the RE20's Variable-D design holds your low end steady without a proximity bump (Electro-Voice), and the Shure MV7+ has both USB-C and XLR outputs (Shure). Prices change often, so check current retailer listings; the specs below link to each manufacturer.

Why XLR Over USB?
XLR microphones need an audio interface or mixer, and in return you get:
Separate preamp: The preamp lives in your interface, so you can choose one with the gain and quality you need.
Upgrade path: You can improve your audio interface separately from your microphone instead of replacing both.
Compatibility: An XLR mic plugs into any interface or mixer with an XLR input, so it moves with you when you change the rest of your setup.
No drivers for the mic: A passive XLR microphone has no firmware or software of its own; the interface handles the computer side.
The trade-off is complexity. You need an audio interface, an XLR cable, and possibly an inline booster. Price the whole chain at current retail before you commit.
XLR Microphones at a Glance
| Microphone | Type | Worth a look if you |
|---|---|---|
| RØDE PodMic | Dynamic | Want a speech-focused mic with internal pop filter and shock mount |
| Shure MV7+ | USB-C and XLR | Want USB now and XLR later |
| Shure SM7B | Dynamic | Want hum shielding and switchable response settings |
| Electro-Voice RE20 | Dynamic, Variable-D | Want minimal proximity effect |
Shure SM7B: Shielded and Versatile
Shure markets the SM7B for broadcasting, podcasts and studio recording (Shure).
What Stands Out
Versatility: Shure describes a flat, wide-range frequency response for clean reproduction of both music and speech, with bass rolloff and presence boost settings.
Electromagnetic shielding: Improved rejection of electromagnetic hum, aimed at interference from computer monitors. In a home office full of gear, that matters.
Built-in protection: Internal shock mounting and a pop filter, so fewer accessories.
The Catch
Shure says the SM7B requires more gain than most entry-level or mid-tier preamplifiers can deliver, and suggests an inline booster or stronger preamp if yours doesn't have more than 60 dB of gain (Shure SM7B guide). So plan for either:
- An audio interface with enough clean gain (check the preamp gain spec), OR
- An inline booster such as the Cloudlifter CL-1 or FetHead
Factor this into your budget.
Specifications (Shure spec sheet)
- Type: Dynamic cardioid
- Frequency response: 50Hz - 20kHz
- Output level: -59.0 dB, 1.12 mV (0 dB = 1 V/Pa at 1kHz)
- Weight: 0.764 kg (Shure SM7B user guide)
Rode PodMic: Built for Speech
RØDE describes the PodMic as optimised for podcasting, livestreaming and other speech applications, per its product page.
What Stands Out
Built-in essentials: Internal pop filter, internal shock mount and an integrated swing mount mean fewer accessories to buy.
Speech-focused: RØDE says the PodMic is optimised for podcasting and speech.
All-metal build: RØDE lists robust all-metal construction.
Sound Character
RØDE's published frequency range is 50Hz to 15kHz, against 50Hz to 20kHz on Shure's SM7B spec sheet. How the two compare on your voice depends on your room and processing, so listen to recordings made in conditions like yours.
Specifications
- Type: Dynamic cardioid
- Frequency response: 50Hz - 15kHz
- Connection: XLR; needs an audio interface
Electro-Voice RE20: Variable-D Broadcast Mic
Electro-Voice calls the RE20 "the mic for broadcast" and describes it as a Variable-D dynamic cardioid (Electro-Voice).
What Stands Out
Variable-D design: Electro-Voice says Variable-D holds your low end steady on and off axis, with no bass-heavy proximity bump when you move in close and no thin edge when you back away.
Test it in your room: Try it in the room you'll record in before committing.
Specifications (Electro-Voice)
- Type: Dynamic cardioid with Variable-D
- Frequency response: 45Hz - 18kHz
Shure MV7+: USB and XLR
The MV7+ has USB-C and XLR outputs (Shure), so you can start simple and move to an interface later.
The Hybrid Advantage
Dual connectivity: USB-C and XLR outputs, so you can plug straight into a computer now and connect to an interface later.
Built-in processing: Shure lists a real-time Denoiser, Digital Popper Stopper and Auto Level Mode.
Touch panel: An LED touch panel on the microphone lets you mute and customize the lighting.
When to Choose It
The MV7+ makes sense if:
- You're not sure whether you'll need XLR later
- You want built-in processing without external software
- You want USB simplicity now without rebuying a microphone when you upgrade
Specifications
- Connectivity: USB-C + XLR

Gain Requirements Explained
Different microphones need different amounts of amplification. This matters when choosing an audio interface.
Compare Published Sensitivity
A lower sensitivity figure means the mic needs more gain from your interface:
- Shure SM7B: −59.0 dB (1.12 mV), where 0 dB = 1 V/Pa (Shure spec sheet); Shure says it needs more gain than most entry-level or mid-tier preamps deliver (Shure SM7B guide)
- RØDE PodMic: 1.4 mV at 94 dB SPL (RØDE)
- Electro-Voice RE20: 1.5 mV/pascal (Electro-Voice)
- Shure MV7+: use it over USB to skip the interface question (Shure)
Solutions for Gain-Hungry Mics
- Cloudlifter CL-1: Inline booster providing up to +25dB of clean gain; regular price $129.00 on Cloud Microphones' site as of September 2026
- FetHead: Inline booster adding +27dB of clean gain; €69.95 on Triton Audio's site as of September 2026
- An interface with more clean gain: Compare preamp gain specs before you buy
Shure also sells the SM7dB, with a built-in preamp that Shure says provides up to +28 dB of gain, so you may not need a separate booster.
FAQ
Is an XLR microphone worth the extra complexity?
If you plan to podcast for years and want room to upgrade, we think so. An interface plus an XLR mic lets you change one part at a time. USB microphones work fine, and the MV7+ gives you both options.
Which XLR microphone is best for untreated rooms?
We suggest a dynamic microphone such as the SM7B, PodMic or RE20 for an untreated room, worked close up. Test in your own room: what matters most is how close you work to the mic and how much reflection is around you.
Can listeners hear the difference between an entry-level and a premium microphone?
We haven't found a published blind listening test comparing these specific microphones on finished podcast audio. Differences show up most in the recording itself and during mixing. Listen to sample recordings in conditions like yours, and treat your room and mic technique as seriously as the microphone.
