- The top 3 Shure vocal mics: the SM58 for the stage, the Beta 58A for demanding live shows, the SM7B for the studio.
- The supercardioid directivity of the Beta 58A tightens the pickup and gives some headroom against feedback when monitors are loud.
- The SM7B requires gain: its low sensitivity demands a generous preamp to deliver a clean, breath-free voice.
- All three rely on a dynamic capsule, which handles powerful voices and remains usable in an untreated room.
The question comes up quite often, whether for PA or home studio: which Shure vocal mic should you choose? The name reassures, and you can see why. The SM58 is the mic that survives years of shows, community halls and foot drops without losing clarity.
But the range of Shure vocal mics is not limited to one model, and the right choice depends first on where you sing. A stage where monitors blast, a rehearsal room, a bedroom turned home studio: each situation calls for a different mic. We picked three references, from live to studio, to help you decide based on your voice, your room and your audio chain.
Comparison of the best Shure vocal mics
Released in 1966 to succeed the 565, the SM58 was designed by Ernie Seeler and his team to withstand the rigors of both stage and studio. It celebrated its fiftieth birthday in 2016 and is still everywhere, from music schools to international tours. Simple, consistent, solid: that’s its whole secret.
Its curve is designed for voice. The midrange is emphasized so you cut through the band, and the lows are slightly reduced. This cut includes the proximity effect, that low-end boost that appears when you sing close to the grille. The diction stays clear, even very close up.
On stage, the cardioid capsule picks up what’s in front and leaves the ambiance aside. The pneumatic shock mount calms handling noise, the built-in pop filter softens "p" and "b" sounds, and the lack of a switch prevents accidental muting mid-chorus. Delivered with its clip, pouch and multi-step adapter, it’s ready to play right out of the box.
Pros
- Curve tailored for voice
- Built-in pop filter
- No switch to accidentally cut off
- Entry point of the trio
Cons
- High end limited to 15 kHz
- No tone switch
Sing two or three fingers away from the grille and keep that distance throughout the song. A dynamic mic rewards consistency: the level stays stable, the bass too, and the sound engineer doesn’t have to chase you on the fader.
The Beta 58A keeps the stage spirit and adds a supercardioid directivity. Its pickup zone tightens forward, with strong side and rear rejection. On a stage where wedges (floor monitors) blast, this feedback resistance makes all the difference at the end of the set, when volume has climbed.
Its response goes up to 16 kHz, with controlled lows and highs that cut through the mix without harshness. Its sensitivity of -51.5 dBV/Pa leaves some headroom: you can push the preamp without bringing up noise, and the dynamics stay clear. The directivity remains consistent across the band, so source separation holds from bass to treble.
It’s not limited to vocals. In home studio, its tight pickup allows clean takes near a guitar amp, a brass section or drum elements, and it copes with an untreated room. The built-in pneumatic suspension absorbs shocks when you pass it from hand to hand.
Pros
- Supercardioid, strong feedback resistance
- Extended highs up to 16 kHz
- Lightest of the trio (278 g)
- Versatile on guitar, brass, drums
Cons
- Requires singing well on axis
- No tone switch
Feedback happens when monitor sound re-enters the mic and loops, causing a whistle. A more directional mic pushes this threshold back, but monitor placement matters just as much: put them where your mic picks up least, and have them checked during soundcheck.
Change of scene. The SM7B was born for radio and television, then established itself in studios for spoken and sung voice. Podcast, streaming, voice-over, recorded vocals: that’s its territory. Its cardioid dynamic capsule delivers a dense, natural voice, on a bandwidth that extends up to 20 kHz.
Two switches adjust the tone at the source. The low-cut filter cleans up the low end, the presence boost brings out intelligibility without heavy post-production. Shielding repels interference from screens, speakers or neon lights, and the internal pneumatic isolation reduces handling and stand noise.
The point to anticipate is its sensitivity of -59 dBV/Pa. It delivers little signal and requires a preamp with gain to spare, whether on a console or a USB audio interface. Plan your chain before adopting it. The yoke mount, standard windscreen, and A7WS windscreen for close miking are included, and it also handles powerful sources: snare drum, guitar, hi-hat.
Pros
- Two tone switches
- Frequency response up to 20 kHz
- Shielding against interference
- A7WS windscreen included for close vocals
Cons
- Requires a preamp with generous gain
- 765 g: designed for a stand, not the hand
Before ordering an SM7B, plug in your current mic and note where your preamp gain sits for a normal vocal take. If it’s already near maximum, budget for an extra gain stage.
FAQ - Choosing your Shure vocal mic
What’s the difference between the SM58 and the Beta 58A?
Both are dynamic mics designed for the stage. The SM58 is cardioid, with a mid-focused curve and a frequency response from 50 Hz to 15 kHz. The Beta 58A is supercardioid: its pickup tightens, which helps against feedback, and its highs extend up to 16 kHz. The choice mainly depends on your stage size and budget.
Can you use the SM7B on stage?
It’s designed for studio and broadcast. At 765 g with a yoke mount, it’s meant for a stand or boom arm, not handheld. For a singer moving on stage, the SM58 and Beta 58A are made for that.
Is the SM58 enough to record your voice at home?
Yes, many demos start with it. Its cardioid capsule leaves out much of the untreated room ambiance, and it plugs easily into an audio interface. For more air in the highs and tone shaping at the source, the SM7B takes over.
Do you need an extra preamp for the SM7B?
It depends on your interface. The SM7B delivers little signal (-59 dBV/Pa) and demands generous gain. If your preamp maxes out before your voice reaches the right level, an extra gain stage becomes useful. Test it with your real voice, at the volume you actually sing.
Why choose a dynamic mic for vocals?
A dynamic mic handles high levels, withstands handling, and mainly captures what’s close to the grille. For a powerful voice, a noisy room, or a stage, it’s a safe choice. The three mics in this comparison all use a dynamic capsule.
How to choose your Shure vocal mic
Before comparing specs, ask yourself a simple question: where will you sing most often? The answer already eliminates half the doubts. The range of vocal mics is vast, and these three Shure models cover three very different uses. The following criteria help you set your priorities.
Stage or studio, the first step
On stage, the mic passes from hand to hand, takes knocks, and must hold up to monitors. The SM58 and Beta 58A are built for that: light, pneumatic suspension, sturdy grille. You put them on a stand, take them off to go to the audience, they keep up.
In the studio, it’s different. The mic stays fixed, and you look for detail and tone control. That’s the SM7B’s world, to set on a stable mic stand or boom arm, given its weight. You adjust it once, at the right height, and it doesn’t move during the session.
Directionality against feedback
Directionality describes the area the mic hears. A cardioid picks up the front and ignores the back. A supercardioid tightens the front even more and rejects the sides more. If you sing in a loud band with close monitors, this tightening gives you more headroom before feedback.
In a quiet room, in acoustic or rehearsal at reasonable volume, the SM58’s cardioid covers the need well. It also forgives placement errors more: you can turn your head a bit toward your musicians without losing your voice in the PA.
Sensitivity and gain, check your chain
Sensitivity tells how much signal the mic sends for the same sound. The lower the number, the more gain you need behind. The Beta 58A (-51.5 dBV/Pa) and SM58 (-54.5 dBV/Pa) plug easily into a rehearsal console or interface. The SM7B at -59 dBV/Pa demands more: check your studio preamps or interface gain reserve before adopting it.
To compare two mics, set them to the same listening level before judging. The louder one always seems better at first listen. Equalize volumes, then focus on the tone and presence of your voice.
Budget, chain included
The three models are clearly spread out. The SM58 is the entry point of the trio, the Beta 58A sits just above, and the SM7B represents the biggest investment. For the latter, think in terms of the full chain: mic, stand or arm, and possibly an extra gain stage if your interface is a bit weak.
Which Shure vocal mic for your voice?
If you sing live and want an ultra-versatile mic, the SM58 has done the job since 1966. If your stage is noisy and monitors are loud, the Beta 58A gives you more headroom. And if your voice lives mainly in recording, podcasting, or streaming, the SM7B brings the density and control expected in the studio.
Many singers end up with two of them: a stage mic in the bag, an SM7B on the desk. The question is which to start with. The best clue is where you’ve sung most often in the last three months.
