Dynamic microphones are one of the most popular types of microphones out there. But as with all microphones, they work best when they’re used properly in the right setting.  

In this ultimate guide, we’ll cover everything you need to know about dynamic microphones, from how they work to their most common uses. We’ll also dive into the differences between dynamic microphones and condenser microphones, before focusing on their maintenance and care. Read on to explore this topic in depth. 

What is a Dynamic Microphone? 

Known for their rugged and durable construction, dynamic mics are well-suited for live performances and untreated environments. To give you a clear understanding of dynamic microphones, we’ll examine how they work, review their key features, and explore their most common uses. 

How Dynamic Microphones Work 

Dynamic microphones convert sound into an electrical signal by means of electromagnetism. These microphones work in a manner similar to how placing a magnet near a coil generates current. Dynamic mics utilize this electromagnetic principle to produce electrical energy, which can then be transformed into audio signals. When the diaphragm vibrates in response to the incoming sound waves, the coils attached to it rapidly move towards and away from the magnet. The movement generates an electric current that travels through the microphone’s wiring. The electricity produced by dynamic microphones tends to be minimal and requires amplification. 

Key Features of Dynamic Microphones 

Dynamic microphones typically have a cylindrical body with a rounded grille at the top. The grille is often a ball-shaped mesh (like the classic Shure SM58) or a flat, barrel-style grille (like the Shure SM57). The body is usually made of metal or heavy-duty plastic, designed to be rugged and withstand drops or rough handling. They’re most commonly available in a handheld form. 

One of their greatest strengths is the ability to handle very high sound pressure levels, which makes them ideal for capturing loud sources like drums, guitar amplifiers, and powerful vocal performances without distortion. These mics produce a warm, natural tone that works well in many settings. Most models feature directional pickup patterns such as cardioid or supercardioid, helping reject unwanted sounds and reducing feedback, especially on stage. Also, they tend to be less affected by humidity, temperature changes, and environmental stress. 

Do Dynamic Microphones Need Phantom Power? 

Dynamic microphones operate entirely without the need for any form of external power, such as phantom power or batteries. Instead, they rely on a simple, rugged electromagnetic design to generate an audio signal. This makes them especially convenient for straightforward, reliable plug-and-play use in a wide range of recording and live sound situations. 

Common Uses for Dynamic Microphones in Broadcasting and Content Creation 

Dynamic microphones are widely used in broadcasting and content creation because of their durability, directional pickup, and ability to handle loud sounds without distortion.  

In radio and podcasting, they’re a popular choice for capturing clear, warm vocals while minimizing background noise, making them ideal for home studios, professional studios, and noisy environments.  

In streaming and live content creation, they’re often used for voiceovers, commentary, and gaming streams, where background sounds need to be suppressed, and a strong, consistent vocal signal is important. They are frequently used for interviews, due to their ruggedness and ability to perform reliably without external power. Many creators use them to record instruments or live performances due to their ability to handle high volume sources like drums or guitar amps without distortion.  

Dynamic Microphones vs. Condenser Microphones 

The two most well-known types of microphones are dynamic and condenser. While both are widely used, key differences like sound quality, portability, and pricing set them apart. 

Understanding the Core Differences 

The overriding difference between the two microphone types is in how they capture sound and the environments in which they perform best. 

Dynamic mics don’t tend to pick up significant background noise. That makes them ideal for podcasting at home or in untreated environments that aren’t soundproof. They don’t tend to overload or distort when capturing high sound pressure level (SPL) sources such as guitar amps, drums, and horns, and don’t require extra power.  

Alternatively, condenser mics capture details and nuances well. They come in two major categories: large-diaphragm and small-diaphragm. Normally, large-diaphragm condenser mics are ideal for studio recording, while small-diaphragm condenser mics are more often used for instrument recording and live sound. However, the smaller version is more sensitive to background noise and requires phantom power. 

Sound Quality Comparison: Dynamic vs. Condenser 

Compared to condenser microphones, dynamic mics are less sensitive to background noise and room reflections, making them a strong choice for untreated or noisy spaces. They are often preferred for use on stage, because they’re sturdy and don’t require external power. In the studio, however, engineers typically choose condenser microphones (or in some cases ribbon microphones) which may be less robust but deliver more detailed sound reproduction.  

Durability and Portability: Which One Wins? 

When comparing dynamic and condenser microphones, dynamic mics are generally recognized as significantly more portable and durable, based on their rugged internal construction and ability to withstand physical impact, temperature changes, and high sound pressure levels without compromising performance.  

Price and Accessibility: What to Consider 

Dynamic microphones are generally more affordable than many of their condenser counterparts, providing reliable, consistent performance at a lower cost and making them an attractive choice for beginners, budget-conscious buyers, and professionals who need sturdy, dependable gear without a high price tag. 

Choosing the Right Dynamic Microphone  

Here’s a look at some of the most popular dynamic microphone options for broadcasting, podcasting, content creation, and live events to help you decide what dynamic mic is right for you and your work. 

Best Dynamic Microphones for Broadcasting 

When it comes to broadcasting, popular high-quality options include the Shure SM7B and the Electro-Voice RE20. Many broadcasters prefer close-micing because it adds warmth and richness to voice, but often shift or move about, forgetting how important it is to stay consistently positioned. Microphones like the RE20 are designed to minimize this issue, allowing natural movement that doesn’t affect sound quality. The Shure SM58 also remains a durable and versatile budget-friendly option, while the Heil Sound PR40 is another great choice for this application. 

Ideal Microphones for Podcasting  

For podcasting, a close-proximity studio microphone, like the Shure SM7dB, delivers a warm, midrange-rich sound. It's not the cheapest dynamic mic, but it holds its own in the studio against condenser mics that cost much more. In recent years, these qualities have given it a new lease on life as the go-to podcasting mic for streamers and YouTubers.  

Top Picks for Content Creators 

The best dynamic microphones for content creators depend on budgetary considerations and setup. Popular options include dynamic mics like the Shure MV7 for a versatile USB/XLR blend. The Maono PD200W Hybrid is another strong option, offering unique wireless capabilities in a dynamic format.  

Best Mics for Live Events 

When selecting microphones for live events, durability is crucial, since they often have to withstand heavy handling, drops, and varying environmental conditions on stage. A dynamic microphone like the Sennheiser e 835 Dynamic Vocal Microphone is a reliable option for both singing and speech. The Sennheiser E935 Dynamic Stage Microphone is another popular choice, as is the Beyerdynamic M 88.
