Shure SM7B Review

A broadcast-standard dynamic that delivers warm, noise-resistant vocals — but it needs a high-gain preamp or inline booster to reach its best sound (score: 8.6; price: £349.00).

The quick answer

If you record podcasts, livestreams or close-miked vocals and want a forgiving, natural broadcast sound, this is one of the few sub‑£400 mics that actually sounds like a pro studio piece. It’s worth £349 if you already own or are willing to buy a clean, high‑gain preamp or an inline booster; if you want plug‑and‑play USB simplicity, skip it.

What we tested

We evaluated the SM7B in XLR configuration over three weeks, running it into a Focusrite Scarlett 2i2 and again with a Cloudlifter CL-1 inline booster. Tests covered close‑miked spoken word, conversational podcasting in an untreated room, and close vocals with and without the included A7WS windscreen.

What it does well

Warm, neutral vocal tone The SM7B’s smooth, flat wide‑range response and selectable presence boost give a natural, broadcast vocal without heavy EQ; voices sit in the mix with less surgery than many condenser alternatives.

Rejects room and background noise Its cardioid pattern focuses on the speaker and rejects off‑axis sound, so you’ll get clearer speech in untreated rooms compared with most condenser mics at similar price points.

Built‑in pop and handling control Internal air‑suspension shock isolation plus the integrated pop filter (and optional A7WS windscreen) keeps plosives and handling noise out of recordings, reducing the need for post‑processing.

Rugged build and humming resistance Sturdy construction and advanced electromagnetic shielding mean less hum when you’re near monitors and studio gear — useful in cramped home setups where kit sits close together.

Simple tonal shaping onboard Selectable bass roll‑off and presence boost let you tailor warmth or clarity at the mic, which frequently saves one round of EQ later in the chain.

Where it falls short

Needs lots of gain — and added cost The SM7B has low sensitivity and typically requires ≈60 dB of clean preamp gain to perform at its best; if your interface can’t deliver that, factor in the cost of a Cloudlifter‑style inline booster or a dedicated mic preamp.

Not plug‑and‑play for beginners If you want USB simplicity or a cheap starter mic, this isn’t it — the SM7B’s setup and extra gear requirement make it a worse choice for people who need a fast, simple solution.

Cardioid rejection is good, not magical The unidirectional cardioid pattern helps with room noise, but it won’t match the isolation of a hypercardioid or a treated vocal booth; noisy environments will still benefit from room treatment or closer microphone technique.

How it compares

The closest competitor at this price is the Electro‑Voice RE20. Choose the SM7B if you want a warmer, more intimate broadcast tone and are willing to add gain; choose the RE20 if you prefer a dynamic that typically needs less preamp gain and sits a bit further forward without as much proximity effect. For most podcasters and streamers who mic up closely, I’d pick the SM7B — but only if you accept the extra cost and setup work for proper gain.
