***SHURE SM Beta 58 Dynamic Vocal Microphone**
Perhaps the most obvious difference is the microphone polar pattern. The SM58 has a cardioid polar pickup pattern, while the Beta 58A is a supercardioid. The polar pattern subsequently affects how you should use the microphone and where it would be most appropriate.
As you can see from the diagrams, a cardioid microphone will reject best from the back while a supercardioid microphone will reject better from the sides. Both microphones pick up sound best from the front, but a supercardioid polar pattern has the added advantage of being more directional and therefore less susceptible to feedback when using correctly placed stage monitors.
Due to its neodymium magnet, the Beta 58A has greater sensitivity and a 4dB hotter output than the SM58
The Beta58 has an extended low-end and high-end compared to the 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.
The Beta 58A is quieter than the SM58 due to its advanced pneumatic shock mount system
The Beta 58A has a hardened grille, which makes it more difficult to dent.
To summarise, the is no doubt an upgrade for many applications, but in some scenarios, these upgrades can also be a hindrance. For example, if you're performing in a heavy-metal band, and you typically shout or scream into your mic - you may not want the extra sensitivity and detail of the Beta58. It's all a matter of application and taste - which do you prefer?
