While it shares the same number as the fabled Shure SM57, the Beta 57A is an entirely different microphone but shares some traits with both the SM57 and the SM58.

Unlike the SM57, the Beta 57A has a grille.

Shure notes that the material of the grille is made of a tougher and more durable material than their SM series.

While the SM58's grille adds space from the capsule and the sound source, the Beta 57A's grille is shorter and therefore shares more with the SM57 with regards to pickup distance.

It also sports a Supercardioid pattern versus the SM57's cardioid.

Lastly, a Neodymium magnet provides a more hi-fi frequency response as well as higher output: perfect for driving mic preamps for that extra grit.


  • Type: Dynamic
  • Polar Pattern: Supercardioid
  • Frequency Response: 50Hz-16kHz
  • Impedance: 150 ohms
  • Applications: Live and recorded guitars, guitar amps, vocals, drums & more


Users are satisfied with the mic's response, saying that it is a definite upgrade over the SM57. It retains some of the characteristics of its lower-priced sibling but adds punch, clarity, consistency (thanks to it's polar pattern). The mic itself is noted by several users to be solid and durable, with some reviewers mentioning they've owned one or several for years without a single breakdown. Baritone vocals shine on the mic.


It may be harsh on female vocals as a few have reported. Highs may be too harsh for some voices.


While it was tailor made for instruments, vocals definitely shine on the Beta 57A especially for deep-voiced singers like Baritones. It may be too bright for some voices and may not be the best pick for a bright snare mic but for balancing out dull or deep sounding sources, it's a great performer at this price range with durability to boot.

Although this was previously on our recommended list, there are now more highly rated options available which you can see in our guide to The Best Dynamic Microphones.
