Shure SM7B

The Shure SM7B is one of the most recognised microphones in professional audio. Originally released in 1973 as the SM7 and updated to the SM7B in 2001, this large-diaphragm dynamic microphone has become the industry standard for vocal recording, broadcasting, and podcasting. Its smooth, warm frequency response and exceptional noise rejection have made it the go-to choice for everyone from radio presenters to rock vocalists — most famously, it was used to record Michael Jackson's vocals on Thriller.

Sound Character

The SM7B delivers a naturally flat, wide-range frequency response from 50Hz to 20kHz with a warm, smooth character that flatters vocals without sounding hyped or harsh. Two switchable response filters on the rear of the mic let you tailor the sound: a bass rolloff that attenuates frequencies below 400Hz to counter proximity effect when close-miking, and a presence boost that adds around 3dB of lift in the 1–10kHz range to help vocals cut through a mix. With both switches off, the response is remarkably even — one of the reasons engineers trust it on such a wide range of sources.

Build and Shielding

The SM7B features an internal electromagnetic shielding system with a humbucking coil that rejects interference from computer monitors, lighting dimmers, and other electronic equipment. This makes it particularly well-suited to home studios and podcast setups where the mic sits close to screens and other gear. The build is tank-like — a steel and aluminium housing with a dark grey enamel finish that feels like it could survive decades of studio use. A detachable foam windscreen is included, along with a close-talk windscreen (the A7WS) for even more pop and wind protection.

Practical Considerations

The SM7B has a low sensitivity rating of -59dBV/Pa, which means it needs a lot of clean gain from your preamp or interface. Budget interfaces may introduce noise at the gain levels required. Many users pair it with a Cloudlifter CL-1 or similar inline preamp to boost the signal before it hits the interface. Shure addressed this with the newer SM7dB, which adds a built-in preamp, but the original SM7B remains the standard.

The yoke mount allows precise positioning, and the XLR output connects with any standard mic cable. There are no pads, no phantom power requirements, and nothing to configure beyond the two response switches — it is straightforward to use.

Who Is This For?

• Podcasters and broadcasters who want broadcast-quality vocals with excellent noise rejection
• Vocalists recording in home or professional studios across any genre
• Streamers and content creators who need a mic that rejects background noise and electromagnetic interference
• Engineers who want a versatile dynamic mic that works on vocals, guitar amps, and drums

The SM7B has earned its reputation through decades of consistent performance. It is not the most detailed or transparent microphone available — condensers will capture more room and high-frequency air — but for close-miked vocals with warmth, presence, and zero fuss, it remains the benchmark.
