Whenever a discussion on the best dynamic microphone comes up, it’s always an opportunity to learn and see what works for others. After all, we can’t all use the same thing the same way.
The best things always come at a price, since the maker must have put so much into them for their uniqueness. This uniqueness could however just be in the design or technologies used, and may not guarantee a top class performance. It may be otherwise too. However, as opposed to that general believe that quality goes with price, paying so much for a microphone does not nullify the fact that something cheaper can do the same job. Price may therefore not be the only criteria for us to determine the best dynamic microphone, but it is worth considering.
So, if all you need is a simple microphone for podcasting, or you will be setting up your home studio soon, you should keep reading. And if you are a pro and wish to upgrade your standard studio or live performance microphones for a better output, this buying guide will ease your decision making on the right choice of dynamic microphone.
Our review covers the best cheap dynamic microphones for you to get things running. You will also learn about some ‘high-class but expensive’ dynamic microphones that are known to deliver an output worth their price. Irrespective of how much you have, it will still fall within the range of the best budget dynamic microphones in this buying guide.
So What is a Dynamic Microphone?
A dynamic microphone is a type of receiver that changes audio signals to electrical signals through electromagnetism. There is a unique name for dynamic microphones coined from their working principle. They are called “moving coil microphones” because they function like a reversed loudspeaker. A dynamic microphone consists primarily of a diaphragm, a magnet, and a voice coil wrapped around it. When we make a sound, it sets the air around the diaphragm into vibration. The movement of the voice coil around the magnet then creates an electric current. The generated current then goes through the cables into the mixer and amplifiers for a boost. The amplified current is then sent back to the speakers through connecting cables to produce sound in a reversed process.
As a measure to cut-off feedbacks in dynamic microphones, they suffer a poor sensitivity to very high frequencies, unlike their condenser counterparts. The physics behind this low sensitivity to high frequencies is in the large mass of the voice coil in a dynamic microphone. It becomes difficult to set the diaphragm into vibration if there isn’t enough energy produced by the air around it, which is the case for high frequencies.
Dynamic microphones come in various sizes, shapes, and designs and are commonly used for live performances because they are sturdier and can withstand pressure.
Dynamic Microphones VS Condenser Microphones
There have been several discussions on dynamic microphones and condenser microphones difference over the years, but here we will clarify and check few relevant facts on them.
It is important to understand that the two receiver types in question do not have the same directional characteristics and they both make use of different transducer principles which makes them unique in their way. Therefore, our “dynamic microphone versus condenser microphone” debate will be a general review of their functionality principles, build, efficiency and performance, both in and out of the studio to help you understand how they work.
1. A dynamic microphone does not require an extra power supply
A condenser microphone relies on a DC polarizing voltage called ‘phantom power’ to produce the required power needed by its transducer elements for the best result. Some of these condenser microphones depend on mixing consoles or microphone preamplifiers to get the needed voltage supply while some others depend on dry cells.
Unlike condenser microphones, all dynamic microphones, apart from the active dynamic type, will perform optimally without any extra power supply. A dynamic microphone, therefore, can save cost and reduce power consumption.
2. High sensitivity limits condenser microphones to the studio
In a live production setup, a condenser microphone due to its high sensitivity may pick feedback noises around, something a producer does not want in his mix. The sensitivity of the condenser microphone can be reduced to this effect too, but there will be a consequent reduction in its loudness.
On the other hand, a well-positioned dynamic microphone on stage can cut-off enough feedbacks because of its lower sensitivity, compared to its condenser counterpart. It is not to say dynamic microphones don’t pick feedback noises too. “Feedbacks” become minimal if the microphone is not so sensitive or built with a multi-directional transducer – a common element in condenser microphones.
3. Dynamic microphones are cheap
There are several high quality, yet cheap dynamic mics out there that can perform as much as their condenser counterparts in and out of the studio.
Unfortunately, most people purchase very expensive gears because they believe anything cheap may suffer in quality, while some believe going for the most expensive gadgets is a show of class and prestige. Most studio standard condenser microphones are very costly, yet delicate. Studio engineers who know what they want rather go after the specs and give it a shot as long as it meets their requirements without breaking their budget. If you are thinking of having your home studio, or want to start your podcast recording in your room, you don’t have to wait till you can afford very expensive condenser microphones. There are several low-cost dynamic microphones to pick from, and anyone of them will be a good way to start something.
4. Condenser microphones are not always as robust
Unlike in dynamic mics where a voice coil of high mass must be set into vibration to produce sound, a condenser microphone makes use of a much thinner gold-plated plastic film. This thin film is delicate and can burnt-out or cut-off if there is too much sound pressure. In that case, condenser microphones work best in a controlled environment rather than around a loud sound source, which is the situation in outdoor live performances.
Also, considering outdoor programs where people can carelessly drop a microphone, pull it down or spill stuff on it, a condenser microphone exposed to that much pressure may get damaged soon. A dynamic microphone will therefore thrive and survive in such situations due to its rigidity.
Dynamic microphones often come in extra weight for a more robust feel and are not as fragile as condenser microphones. Dynamic microphones are always ready for the road and perfect for any outdoor show.
It will not be correct to say dynamic mics are better than their condenser counterpart since condenser microphones serve specific purposes. But if we would go by, which of these two receiver types have a healthy lifespan and a wide range of usage out there, dynamic microphones will have it.
Dynamic microphones are not without limitations too, but they are still a better choice than the condenser microphone especially for an out-of-the-studio performance. Here are few drawbacks of most dynamic microphones.
- It has a cardioid pick-up pattern
A dynamic microphone will not be able to pick audio signals from more than one direction. In situations where backups are out of microphones, and about one or two of them will need to share a single microphone, its loudness would suffer, and the vocalist directly in front becomes more audible than the others. Dynamic microphones, therefore, can only pick signals if the projected sound is parallel to the direction where it points. Consequently, this means more microphones will be needed to serve a larger number of backups when a single condenser microphone can just do the job.
- Low sensitivity to high frequencies
Just like other kinds of microphone, a dynamic microphone has its frequency range, and this varies depending on which product you choose. But in general, condenser microphones do have a sensitivity that is much higher than what a dynamic microphone can possess. It is as a result of the thin gold-plated film in their transducers which vibrates at any slight audio signal. It becomes a limitation for dynamic microphones in situations where you need to pick distant audio signals.

What You Need to Record with a Dynamic Mic
It is important to learn about everything that surrounds the use of dynamic microphones before going for one. You need to understand the right positioning for studio use or live performances, and how you can help its final output quality. But not no worry, this buying guide got it all covered for you!
As we have discussed the features and downside of a dynamic microphone earlier, it will be a good thing to come up with ways to optimize its performance or cover-up its lapses too. Below are few things worth considering;
1. A GOOD ACOUSTIC TREATMENT
You must take into account your recording environment. If you are recording with your dynamic microphone in a standard studio with a proper padding, then you should worry less. You have the standard environment for recording.
If you are using your dynamic microphone in your improvised home studio, however, you have to reduce the room’s acoustics even if you won’t be able to eliminate it entirely.
For your podcasts or vocal recording in a room without proper padding, you should consider getting an acoustic isolation shield which looks like a mini-voice booth. If its price is out of your budget, you can as well improvise. You can get a cushion large enough to cover the ceiling and at least two of the four walls of the room. You can then position your dynamic microphone well in the angle between the cushioned walls. The cushion will absorb sound waves that could be bouncing back into the microphone. It will do well to eliminate echoes.
Microphones do not have their power sources, except for condenser microphones that make use phantom power. In that case, a dynamic microphone’s mic-level signal is not enough to move the cones of a loudspeaker. It, therefore, calls for an additional boost of that signal to line-level with an extra power source, hence the need for a preamplifier.
3. CONVERTERS FROM ANALOG TO DIGITAL
If you will be doing a direct vocal recording into computer software, there is a need for a converter to translate the electric signals of the microphone to digital signals in a binary language that a computer understands. This conversion is carried out by an ADC, an element in sound cards. It is until conversion into binary signals has been done that digital editing of the recorded signals will be possible. It is, therefore, important to get yourself a good one as this analog to digital converter is what will determine the quality of your digital production outputs.
4. AN AUDIO INTERFACE: ALL-IN-ONE
An Audio Interface is the all-in-one solution that helps you upgrade the signals from your computer’s audio output. There are hundreds of audio interfaces available out there for different purposes, and choosing the right one could be a bit confusing because they all come with varying strength and features. Some are specially built for outdoor performances while some are only good in the studios. Identifying the right one that will deliver is more important than what your budget is if you are buying for professional use.
Irrespective of the design, build and size of an Audio interface, the important features that should determine your choice includes its form factor, its microphone preamp channels, its compatibility with digital audio workstations, and its input and output count.
Condenser microphones depend on some extra phantom power to function optimally. It is a different case for dynamic microphones as they do not rely on this to perform well. Conventional mixers and preamps now have provisions for condenser microphones that require the extra phantom voltage of about 48 Volts.
If you connect a dynamic microphone into a phantom power, it is unlikely to be harmed by the high voltage. But for best practices, you should always turn the phantom power off when a condenser microphone is not on the mixing console.
