SM58 VS BETA 58A Comparison

SM58 VS BETA 58A Comparison

The Shure SM58 and Shure Beta58A are both popular dynamic microphones that are widely used in live performances, but they do have some noticeable differences that suit specific applications.

Shure SM58 Microphones

The SM58 is known for its warm and smooth sound signature, making it a staple for vocalists across various genres. It has a presence peak in the upper midrange, which helps to cut through the mix and provide clarity to vocals.

Shure BETA 58A Microphones

On the other hand, the Beta58A is designed to offer a brighter and more detailed sound. It has a higher output level, which provides a crisper and more present sound, making it suitable for vocalists who need to project their voice in louder environments or for genres that require more emphasis on treble frequencies.

  • Polar pattern: Beta 58A = supercardioid; SM58 = cardioid

    The polar pattern subsequently affects how you should use the microphone and where it would be most appropriate.

  • Output level: Beta 58A is 4dB hotter than SM58

    Due to its neodymium magnet, the Beta 58A has greater sensitivity and a 4dB hotter output than the 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

    This does not necessarily mean the Beta58 is better, and depending on the style/tonal characteristic of your voice, you may or may not benefit from the extended frequency response.

Overall, while both microphones are exceptional choices, the SM58 tends to provide a classic and versatile sound, while the Beta58A offers a more modern and brighter tone for specific applications. The Beta 58A is no doubt an upgrade for many applications, but it might not be a case for some scenarios. For example, if you are performing in a heavy-metal band, you may not want the extra sensitivity and detail of the Beta 58A.
