Shure now sells three microphones that look like members of the same family, and in a sense they are. The SM7B is the original, a broadcast dynamic microphone that has been in production in one form or another since 1973\. The SM7dB is the same microphone with a small preamplifier built into its body. The MV7+ is the creator version, inspired by the SM7B but with a USB (Universal Serial Bus) connection, onboard processing and a light-up touch panel. All three sit in the same price neighborhood, all three get recommended for podcasts, vocals and streaming, and buying the wrong one usually means spending more money a month later. Here is how they really differ and which one we would buy for each kind of setup.

## The quick answer

- **Buy the SM7dB** if you are starting from scratch with an audio interface and XLR, the three-pin professional microphone connector. It solves the SM7B's one real problem for less than the cost of fixing it separately.
- **Buy the SM7B** if you already own a high-gain preamp or an inline booster, or you record loud sources such as singers and guitar amps.
- **Buy the MV7+** if you do not own an interface and want to plug one microphone straight into a laptop or phone and sound good tonight.

## The radio microphone that made Thriller

The SM7 story starts with the SM5, a dynamic boom microphone Shure introduced in 1964 for television and film studios. Late in that decade Shure set out to build something for recording studios, radio stations and voiceover booths, and the SM7 arrived in 1973 as part of its SM line, short for Studio Microphone. Its diaphragm was made thinner, and so more flexible, than usual, and the housing left a larger pocket of air behind the cartridge. Both choices push the low end forward, which is exactly what radio voices wanted. It cost $257 at launch, which Shure calculates as about $1,741 in today's money.

Then music found it. The SM7 recorded most of Michael Jackson's vocals on Thriller, a radio microphone on the best-selling album ever made, and it has stayed in studios ever since for vocals, guitar cabinets and even drums. The SM7A replaced it in 1999, and the SM7B followed in 2001 with a larger windscreen. Today's SM7B ships with a second close-talk windscreen, the A7WS, for speech right up against the grille. If you want the full story of the microphone on its own, our [Shure SM7B guide](https://www.unknowndivide.com/shure-sm7b-dynamic-microphone/) goes deeper.

The design has barely changed, and neither has its famous quirk. The SM7B is a quiet microphone. Shure rates its sensitivity at -59 dBV/Pa (decibels relative to one volt per pascal of sound pressure), which works out to just 1.12 millivolts. Point it at a normal speaking voice and your interface has to supply a lot of clean gain to bring that up to a healthy level. Many entry-level interfaces can do it only near the top of their gain knob, where hiss creeps in. That is why so many SM7B owners end up buying a second box.

## SM7B vs SM7dB: the gain problem, solved

![Singer wearing headphones performing into a Shure SM7dB microphone on a stand in a vocal booth with acoustic panels](https://storage.ghost.io/c/25/41/254117cc-2631-4fb7-9f78-fa31eac12f1a/content/images/2026/11/shure-sm7db-singer-vocal-booth.jpg)

That second box is usually a Cloudlifter, a small inline gain booster that runs on phantom power. The SM7dB simply moves the idea inside the microphone. Shure designed the built-in preamp itself, using technology licensed from Cloud Microphones, the company behind the [Cloudlifter CL-1](https://www.unknowndivide.com/cloudlifter-cl-1/). A switch on the back gives you three positions: bypass, +18 dB or +28 dB. In bypass the SM7dB behaves exactly like an SM7B, at -59 dBV/Pa. At +18 dB it reads -41 dBV/Pa, and at +28 dB it reads -31 dBV/Pa, which is enough to make a modest interface sound relaxed rather than strained.

There is one requirement. The preamp is powered by 48 volt phantom power, so your interface or mixer must supply it, and almost all do. If you are unsure what that means, our guide to [phantom power](https://www.unknowndivide.com/what-is-phantom-power-48v-explained/) explains it in two minutes. The cartridge, the cardioid pickup pattern, the 50 hertz to 20 kilohertz frequency range and the bass roll-off and presence boost switches are the same as on the SM7B. Shure's stated aim was to keep the classic sound "unchanged", and the bypass position lets you check for yourself.

So why does the SM7B still exist? Because not everyone needs the extra gain. A singer belting into it, a guitar amp or a snare drum produces plenty of level on its own, and a studio with good preamps never misses the booster. The SM7B is also slightly heavier at 852 grams against 837 grams for the SM7dB, a difference no boom arm will notice.

The money is where it gets interesting. In mid-November the SM7B was selling for $369 against a list price of $439, and the SM7dB for $459 against $549\. A Cloudlifter CL-1 was around $128\. Add that booster to an SM7B and you pay about $497, more than the SM7dB, for a setup with an extra cable and an extra box on the desk. Unless you already own a booster, the SM7dB is the cheaper way to get the SM7 sound working properly.

## SM7B vs MV7+: a different kind of microphone

![Man in headphones speaking into a black Shure MV7 plus podcast microphone with a glowing touch panel in a room lined with blue acoustic foam](https://storage.ghost.io/c/25/41/254117cc-2631-4fb7-9f78-fa31eac12f1a/content/images/2026/11/shure-mv7-plus-podcast-microphone-led-panel.jpg)

The MV7+ borrows the SM7B's silhouette and its job description, but it is a computer peripheral as much as a microphone. It has both a USB-C port and an XLR output, so it can plug straight into a laptop or phone, or into an interface later if you grow into one. Inside it does a lot of work on your behalf with DSP (digital signal processing). Voice Isolation Technology separates your voice from the room, a real-time denoiser removes steady background noise, an Auto Level Mode adjusts gain based on your distance and volume, and a Digital Popper Stopper cleans up plosives. There are three onboard reverbs, Plate, Hall and Studio, plus a 3.5 millimeter headphone jack for monitoring with no delay.

The touch panel on top is an LED (light-emitting diode) strip with 16.8 million color options in Shure's free MOTIV Mix app. It works as a level meter, and tapping anywhere on it mutes the microphone, which anyone who has coughed during a livestream will appreciate. At 574 grams it is also much lighter than either SM7, so cheaper boom arms and desk stands hold it comfortably.

The trade-offs are real. Shure lists the MV7+ frequency response as 50 hertz to 16 kilohertz, against 20 kilohertz for the SM7 pair, so it gives up some of the air at the top that singers and acoustic instruments use. And all that processing is a convenience for speech, not a substitute for a quiet room when you are recording music. It lists at $299 and was selling for $255 in black in mid-November, the least expensive of the three by a clear margin, and it needs nothing else to work.

## Which Shure mic should you buy

- **The podcaster with a budget interface:** the SM7dB on +28 dB. You get the classic broadcast sound without riding the gain knob into the hiss. Pair it with something like the [Focusrite Scarlett 2i2](https://www.unknowndivide.com/focusrite-scarlett-2i2-4th-gen-audio-interface/) and you are done.
- **The singer recording at home:** the SM7B if your interface has strong preamps, the SM7dB on +18 dB if it does not. A dynamic microphone forgives an untreated bedroom far better than a condenser, as our guide to [condenser vs dynamic microphones](https://www.unknowndivide.com/condenser-vs-dynamic-microphones-explained/) explains.
- **The streamer or solo podcaster with just a laptop:** the MV7+. Plug in, tap to mute, let Auto Level handle the rest.
- **The guitarist miking an amp:** the SM7B. A loud cabinet gives it all the signal it needs, so the built-in preamp would sit unused.
- **The owner who already bought a Cloudlifter:** the SM7B. You have already paid for the fix.
- **The two-person show:** two SM7dBs into a two-input interface. Two USB microphones on one computer is a headache that an interface avoids.

## Our call

**Our call: buy the SM7dB.** For anyone starting an XLR setup today it is the SM7B with its one weakness fixed, and at current prices it costs less than an SM7B plus a booster. Buy the plain SM7B only if you already own the gain to drive it or you are recording loud sources. Buy the MV7+ if you never want to own an interface; it is the easiest of the three to sound good on, just not the one to grow into a music studio with.
