Shure SM7B (2001–)
A broadcast dynamic that spent two decades as a studio secret before podcasting made it the most recognizable microphone on the internet.
Overview
The Shure SM7B is a cardioid dynamic microphone introduced in 2001. It succeeded the SM7A and is the flagship of the SM7 series. It has a warm, flat frequency response that picks up natural vocal tones clearly and rejects off-axis noise. That made it a broadcast standard long before a webcam ever pointed at one. It turns up in radio studios, scoring stages, and bedroom podcast rigs alike.
The physical package explains a lot of the devotion. Shure builds the SM7B around a rugged all-metal body of dark gray enamel aluminum and steel, and the thing feels like it could survive being dropped down a stairwell. At 766 grams according to Thomann's published figures, it is a substantial piece of hardware on the end of a boom — heavy enough that a cheap desk stand will sag under it. Dimensions run 190 x 64 x 96 mm. The locking yoke mount uses a captive stand nut on standard 5/8-inch–27 threads and allows up to 90 degrees of rotation, so angling the capsule toward a seated announcer is a matter of loosening two nuts rather than fighting a clip.
Inside, the design is aimed at close-miked voice. An internal air-suspension shock mount, with the isolator integrated directly into the microphone's structure, keeps handling noise and stand vibration out of the signal. A humbucking coil reduces electromagnetic interference by up to 11 dB at 60 Hz. That helps when the mic sits inches from a computer monitor or a bank of neon. Two switchable filters do the tonal work: a bass roll-off to tame proximity effect for close-talk work, and a mid-range presence boost for intelligibility. The cartridge is an enhanced Unidyne III with a thinner diaphragm and larger air volume than the SM57's, which Shure credits with superior low-end reproduction. The frequency range is quoted at 50 - 20,000 Hz.
This catches first-time buyers: the SM7B is a low-output dynamic, and Shure recommends at least +60 dB of preamplifier gain for optimal performance. It wants a decent preamp, or one of the inline boosters the market has built around this model.
Historical Context
The SM7B descends from Shure's broadcast microphones, a line that begins with the original SM7, launched in 1973 for radio and television announcers at an initial price of $257. That price belongs to the 1973 model, not the SM7B, and resale listings mix the two up constantly. The SM7A followed in 1999, and the SM7B arrived in 2001 as its successor and the series flagship.
The SM7 family was used on Michael Jackson's Thriller album in the 1980s, engineered by Bruce Swedien. That predates the SM7B itself but attaches to the whole SM7 family. By the mid-2000s the SM7B was already a working studio tool, appearing alongside the SM57 in sessions such as bassist Dave Hernandez's rig, where his amps were miked with the two Shure models respectively (Mix, December 2007, p.77). Through the 2000s and 2010s its popularity grew among podcasters, streamers, and content creators. In 2020 Shure released the MV7, a hybrid USB/XLR microphone inspired by the SM7B's design. In 2023 it introduced the SM7dB with a built-in preamp and released a signature edition SM7B to mark the product line's 50th anniversary.
