If you’ve spent any time looking at professional studio setups, you’ve seen these two microphones. They are the “Big Two” of the broadcast world. Both are large-diaphragm dynamic mics, both have legendary status, and both are built like tanks.
But while they often compete for the same desk space, they offer distinct experiences. Here is the breakdown of how the Shure SM7B and the Electro-Voice RE20 stack up.
The Sound Signature
- Shure SM7B (The Smooth Operator): The SM7B is famous for its “radio ready” sound. It has a flat, wide-range frequency response that leans toward being warm and silky. It excels at smoothing out harsh voices and provides a natural “low-end bloom” that makes almost anyone sound more authoritative.
- Electro-Voice RE20 (The Honest Workhorse): The RE20 is known for its clarity and accuracy. It doesn’t “color” the voice as much as the SM7B. It provides a very balanced, natural mid-range, making it a favorite for broadcasters who want their voice to sound exactly like it does in the room.
Key Features & Performance
| Feature | Shure SM7B | Electro-Voice RE20 |
| Variable-D Technology | No | Yes (Eliminates proximity effect) |
| Output Level | Very Low (Requires a high-gain preamp) | Low (Moderate gain needed) |
| Internal Pop Filter | Excellent | Very Good |
| Mounting | Integrated Yoke | Requires external clip/shock mount |
The Proximity Effect Factor
The RE20 features Variable-D technology, which is a game-changer for many. Most microphones get “boomy” or bass-heavy as you get closer to them (the proximity effect). The RE20 stays consistent regardless of how much you move around the mic, making it much more forgiving if you tend to lean in and out while recording.
Gain Requirements
The SM7B is notoriously “gain-hungry.” To get a clean signal without cranking your interface into the hiss zone, you’ll likely need a dedicated preamp or an inline booster (like a Cloudlifter or FetHead). The RE20 is more sensitive and generally easier to drive with standard audio interfaces.
Design Aesthetics
The SM7B sports a sleek, dark, and modern look that has become the visual standard for video podcasts and streamers. Its integrated foam windscreen and yoke mount make it look incredibly clean on a boom arm.
The RE20 has a classic, industrial “Steelie” look. It’s iconic in a vintage way, often associated with legendary radio booths. It’s a bit bulkier and usually requires a separate shock mount, which adds to its footprint on camera.
Which One Should You Choose?
- Pick the Shure SM7B if: You want that “thick,” polished podcast sound, you have a high-quality preamp, and you want a mic that looks modern and sleek on your video feed.
- Pick the Electro-Voice RE20 if: You want absolute vocal clarity, you tend to move around a lot while talking, or you want a microphone that is a literal piece of broadcasting history with no-nonsense performance.
Final Verdict: You truly can’t go wrong with either. The SM7B favors the “vibe,” while the RE20 favors “precision.” Both will last you a lifetime.
