In this article, we’ll delve into the world of microphone technology and explore the truth behind the SM58’s classification.
Understanding Microphone Types
Before we dive into the specifics of the SM58, it’s essential to understand the fundamental differences between condenser and dynamic microphones.
Condenser Microphones
Condenser microphones are known for their high sensitivity and wide frequency response. They consist of a thin diaphragm suspended between two electrodes, which creates a capacitor. When sound waves hit the diaphragm, it vibrates, changing the distance between the electrodes and creating an electrical signal. Condenser microphones require an external power source, known as phantom power, to operate.
Condenser microphones are commonly used in studios and live performances where high-fidelity sound reproduction is crucial. They’re ideal for capturing the nuances of instruments and vocals, making them a popular choice for acoustic guitar, orchestral recordings, and podcasting.
Dynamic Microphones
Dynamic microphones, on the other hand, are sturdy and can handle high sound pressure levels. They consist of a coil suspended in a magnetic field, attached to a diaphragm. When sound waves hit the diaphragm, the coil moves within the magnetic field, generating an electrical signal. Dynamic microphones do not require an external power source and are often used in live performances, public speaking, and recording loud instruments.
The SM58: A Dynamic Microphone
So, what type of microphone is the SM58? The answer is clear: the SM58 is a dynamic microphone. Shure, the manufacturer, explicitly states that the SM58 is a unidirectional dynamic microphone. Its cardioid polar pattern, rugged design, and ability to handle high sound pressure levels all point to its dynamic nature.
But why do people think the SM58 is a condenser mic? There are a few reasons for this misconception:
High-Quality Sound
The SM58 is known for its clear, crisp sound and high-frequency response, which is unusual for dynamic microphones.

What is the SM58 Conundrum?
The SM58 Conundrum refers to the long-standing misconception that the Shure SM58 is a cardioid dynamic microphone. This myth has been perpetuated by many in the music industry, including musicians, sound engineers, and even Shure’s own documentation. However, the truth is that the SM58 is actually a unidirectional microphone with a frequency response tailored to emphasize the human voice.
Despite the myth, the SM58 has remained a beloved and widely used microphone in the music industry. Its durability, versatility, and affordability have made it a staple in many live performances and recording studios. The SM58 Conundrum highlights the importance of understanding the technical specifications of audio equipment and not relying solely on conventional wisdom or hearsay.
Is the SM58 really not a cardioid microphone?
Yes, that’s correct. While the SM58 is often referred to as a cardioid microphone, its polar pattern is actually unidirectional. The main difference between cardioid and unidirectional microphones lies in their pickup patterns. Cardioid microphones have a heart-shaped pickup pattern, which captures sound from the front and rejects sound from the sides and rear. Unidirectional microphones, on the other hand, have a more focused pickup pattern that primarily captures sound from the front.
The SM58’s unidirectional design is intended to help reject background noise and feedback, making it well-suited for live performances and public speaking applications. Its frequency response is also tailored to accentuate the human voice, which is why it’s often used for vocals. Despite the misconception about its polar pattern, the SM58 remains a popular choice among musicians and sound engineers.
Why does the myth about the SM58’s type persist?
The myth about the SM58’s type has persisted for several reasons. One reason is that Shure’s own documentation and marketing materials have historically referred to the SM58 as a cardioid microphone. This has contributed to the widespread misconception and made it difficult to correct. Another reason is that the terms “cardioid” and “unidirectional” are often used interchangeably, even though they have distinct differences in terms of pickup patterns.
Additionally, many musicians and sound engineers have learned about microphones through hands-on experience and word of mouth, rather than formal education or training. As a result, they may not have a deep understanding of microphone types and polar patterns. The myth has simply been perpetuated through repetition and a lack of clear information.
