Gearank Recommendation

The Beta 57A appeared on our recommended list for Dynamic Microphones from June 2020 until May 2021.


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.

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

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.
