Shure SM7B vs RE20: Which Podcast Mic Wins?

Sound Showdown: Frequency & Performance

After analyzing Audio University's side-by-side tests, I can confirm both mics deliver broadcast-quality vocals but with distinct sonic signatures. The Shure SM7B ($400) features a low-mid dip and 5kHz boost that cuts through mixes – ideal for voices needing presence. Meanwhile, the Electro-Voice RE20 ($450) counters with dips at 2kHz/4kHz and an 8kHz lift for smoother highs. In proximity tests, the RE20 demonstrated slightly better off-axis rejection, though both leveraged their cardioid patterns effectively to minimize room noise.

Critical insight from testing: While the SM7B's mid-scoop helps reduce boxiness in untreated spaces, the RE20's extended top-end captures more vocal nuance. For deep voices, the SM7B's low-end roll-off prevents muddiness, whereas the RE20's flatter response suits versatile vocal ranges.

Practical Considerations: Setup & Value

Gain Requirements

Both mics demand significant clean gain – a lesson reinforced when Kyle maxed his Focusrite Scarlett 2i2 preamps. I recommend interfaces with 60dB+ gain or inline boosters like Cloudlifter. Budget-conscious creators should note: the SM7B works adequately with mid-tier interfaces, while the RE20 often requires premium preamps.

Physical Design Differences

• Mounting: The SM7B's integrated swivel mount allows quick adjustments during podcasts. The RE20's stock mount tends to sag without its $100 shock mount (adding 25% to total cost).
• Aesthetics: Video podcasters often prefer the SM7B's iconic look. The RE20's broadcast-style design suits radio studios better.
• Durability: Both feature all-metal construction, though the SM7B's internal suspension better isolates handling noise.

Pro tip: RE20 users should invest in the shock mount immediately – its front-heavy design causes fatigue during long sessions.

The Verdict: Which Mic Should You Buy?

Based on cost-to-performance ratio, I recommend the Shure SM7B for most podcasters. At $400 with no add-ons needed, it delivers 90% of the RE20's quality while saving $150. However, voiceover artists capturing subtle vocal textures should consider the RE20 despite its premium.

Industry perspective: Major podcasts like The Joe Rogan Experience standardized the SM7B for a reason – it consistently delivers that "radio-ready" sound with minimal processing. The RE20 remains the gold standard in broadcast booths but demands optimal acoustic environments.

Your Podcast Mic Toolkit

Actionable checklist:

1. Test your interface's preamp gain (aim for 55-65dB headroom)
2. Allocate $100 extra for RE20 shock mount if choosing EV
3. Position mic 3-4 inches from mouth to minimize plosives
4. Use a pop filter regardless of model
5. Record test clips in your actual recording space

Recommended gear:

• Interfaces: Audient iD14 (clean gain) > Focusrite Scarlett (entry-level)
• Boosters: Cloudlifter CL-1 ($149) for SM7B, FetHead ($99) for RE20
• Acoustic Treatment: Kaotica Eyeball ($120) for untreated rooms
