Vocal microphone provides a brightened midrange and bass roll-off with frequency response to control proximity effect, a steel mesh grille for durability, a shock mount for low unwanted noise, and a neodymium magnet for high signal-to-noise ratio.

  • Frequency response tailored for vocals, with brightened midrange and bass rolloff to control proximity effect
  • Uniform supercardioid pattern for high gain before feedback and superior rejection of off–axis sound
  • Neodymium magnet for high signal–to–noise output
  • Hardened steel mesh grille that resists wear and abuse
  • Advanced pneumatic shock mount system that minimizes transmission of mechanical noise and vibration
  • Minimally effected by varying load impedance
  • Legendary Shure quality and reliability

What is the Beta 58A best suited to?

The Beta 58A is a premium vocal mic ideally suited for professional lead and backup vocals, either on stage or in the studio.

How does this compare to the legendary SM58?

Both are designed for vocal use and have a bright midrange and bass roll-off. The Beta 58A has increased sensitivity and high-end frequency response which results in a cleaner more detailed sound. It also features a supercardioid polar pattern compared to the SM58’s cardioid, giving it greater unwanted sound rejection and more resistance to feedback.

Beta 58A Wireless Options

As a wireless microphone the Beta 58A is available in different wireless systems - analogue and digital.


How does it differ to the Beta 57A?

The form factor of the mics is different. The different grilles influence the frequency response resulting in a slightly different sound reproduction in the higher frequencies. In addition, the Beta 57A grille allows a little closer placement of the microphone cartridge, which translates to higher output, more gain before feedback, and a more bass response due to the proximity effect.

How does it differ to the Beta 87A/C?

The Beta 58 uses a dynamic element; the Beta 87 a condenser. That’s why they sound different. It will be a matter of personal preference, not a technical choice. Auditioning both at a Shure dealer is our best advice.

How does it differ to the SM58?

There are several differences between the two mics. Here are the most relevant ones: Polar pattern: Beta 58A = supercardioid; SM58 = cardioid Output level: Beta 58A is 4dB hotter than SM58 Handling noise: Beta 58A has less handling noise than the SM58 Grille: Beta 58A has a hardened grille that is very difficult to dent Frequency response: Beta 58A has extended low and high end compared to SM58

Is there a version with a switch?

No, there is no switch version available. You might want to have a look at the SM58SE which is an SM58 version that uses a switch.

Is there a wireless version available?

A Beta 58A head is available for all current Shure wireless microphone systems except for BLX and GLX-D.
