About the Shure SM7B

The Shure SM7B is the most recognizable broadcast and podcasting microphone in the world, but its roots are in recording studios — it was the mic used for Michael Jackson's "Thriller," and it has been a staple of radio and music production since the 1970s. Four distinct variants have been produced since the original SM7 launched in 1973, each adding features while retaining the core dynamic cardioid capsule design. The SM7B (2001–2023) became the default recommendation for home studios and podcasters; the SM7dB (2023–present) added a built-in preamp for interfaces with limited gain. Confusion between variants is widespread on the used market — sellers frequently list older SM7 or SM7A models as "SM7B" without realizing they're different products.

Tone Character

Smooth, flat frequency response with gentle presence boost option; proximity effect gives warmth at close range; rejects room noise well

Buying Guide

  • 1Verify the exact variant before buying: SM7, SM7A, SM7B, and SM7dB are all different microphones. The SM7B is the most common and most versatile; the SM7dB adds a built-in preamp. Check the label on the bottom of the mic.
  • 2The SM7B requires significant gain — around 60dB for a quiet voice. If your interface has a noisy preamp or limited headroom, budget for a Cloudlifter or inline preamp, or consider the SM7dB instead.
  • 3Counterfeit SM7Bs exist. Check that the Shure logo on the body is engraved (not printed), the yoke mount feels solid metal (not hollow plastic), and the EQ switches click firmly.

Shure SM7 Variant Guide — SM7, SM7A, SM7B, and SM7dB

Four distinct SM7 variants have been produced since 1973. They share the same dynamic cardioid capsule concept but differ in features, EQ switching, and electronics. Used listings frequently mislabel older variants as SM7B — verify before buying.

How to Read Your Serial Number

The Shure SM7 series does not use serial numbers as a meaningful identifier for dating or authentication — Shure does not publish serial-to-date databases for these models. Variant identification is done by the model designation on the nameplate (on the bottom of the mic body), the presence or absence of EQ switches (SM7A/B/dB have them; original SM7 does not), and the presence of a built-in preamp (SM7dB only). If you need to confirm the exact production date for warranty or documentation purposes, contact Shure directly with the serial number.

Spotting a Counterfeit or Mislabeled SM7B

  • 1Check the nameplate on the bottom of the mic — it must clearly read the correct model designation (SM7B, SM7dB, etc.). Sellers sometimes describe the wrong model; always verify the physical label.
  • 2The Shure logo and model text on the body should be engraved or screened clearly — not a sticker or worn decal.
  • 3The detachable yoke mount (SM7B and SM7dB) should feel solid and metal. Counterfeits often use hollow or lightweight plastic yokes.
  • 4Both EQ switches should click firmly between positions. Sloppy or intermittent switches indicate either a counterfeit or a damaged unit.
  • 5The internal pop filter is a foam disc inside the headgrille — it should be present and intact. Missing foam can increase plosive noise.
