Shure SM7dB — Editorial Review

The Shure SM7dB takes the legendary SM7B broadcast dynamic microphone and adds a built-in active preamp, solving the SM7B's biggest practical headache: its very low output. For podcasters and streamers without a high-gain interface, that changes everything.

The SM7B sound, minus the gain problem

Sound On Sound and MusicRadar note the integrated preamp — built on technology licensed from Cloud Microphones — adds a switchable +18dB or +28dB of clean gain, so you no longer need an external booster like a Cloudlifter. The warm, smooth SM7B voicing and strong off-axis rejection are unchanged, making it forgiving in untreated rooms. In Podcastage's review and test — featured above — it's compared head-to-head against other broadcast dynamics.

Honest cons

• Requires phantom power. Uniquely for a dynamic mic, the active preamp needs +48V — so it won't run on gear that can't supply it.
• Redundant for some SM7B owners. If you already own a capable preamp or Cloudlifter, you're paying for gain you don't need.
• Heavy. At ~837g it needs a sturdy boom arm.
• Cardioid dynamic limits. It won't match a condenser's airy detail or offer other polar patterns.

Where this microphone fits

• Podcasters and streamers using interfaces or mixers that lack high clean gain.
• Broadcasters and voice artists who want the iconic SM7B tone with plug-and-play levels.
• Untreated-room recordists who benefit from strong background rejection.
• Not existing SM7B-plus-preamp owners, condenser-detail seekers, or gear without phantom power.
