Whether you plan on creating a podcast/newscast, recording music, or entertaining an evening of karaoke at home, a dependable microphone plays a crucial role. Although most microphones stick to a familiar form – it’s like handling a flashlight, except that the business end records audio instead of illuminates – you can find ones exhibiting a little more creativity with different shapes and sizes. And as with many other types of modern technology, microphones can showcase a variety of specialties and useful features.

Microphones are sold across a wide range of prices. Affordable models can be had for less than US$50, while the expensive (often considered for professional use) ones can add up to the thousands of dollars. Some common examples of microphones:

  • Single/multiple polar patterns (how the microphone isolates the sound to be recorded)
  • Battery-powered
  • Wired/wireless recording
  • On-mic volume/gain/mix controls
  • Additional connection options

Despite there being a lot to choose from, almost every single microphone will fall into one of two basic types: dynamic and condenser. The other, less common kind you can encounter is the ribbon microphone. Although each is a transducer that performs the similar duty of picking up and capturing sound, the methods of creating electronic output signals are quite distinct.

Depending on the particular recording needs/situations, one may be the better option over the other. The thing is, it's terribly difficult to tell the different types apart just by looking at them. So here’s what you should know.

Dynamic Microphones

Typically you can relate the operation of dynamic microphones to that of a traditional (i.e. passive) speaker, but in reverse. So with a traditional speaker, the audio signal travels from the source all the way to the voice coil, which is attached to a cone (also known as a diaphragm). When electricity (the audio signal) reaches the coil, a magnetic field is created (electromagnet principle), which then interacts with the permanent magnet located right behind the coil. The fluctuation of energy causes the magnetic fields to attract and repel, forcing the attached cone to vibrate back and forth, which is what produces the sound waves that we can hear.

So in reverse, a dynamic microphone picks up sound pressure, which vibrates the cone and causes the magnetic fields to interact, resulting in the creation of an electric signal. One great benefit of dynamic microphones is that they can work passively. This means you can use them without the need of any external power, since the current that creates the output signal is generated through the electromagnetic action. However, there are some active dynamic microphones – usually of higher quality and expense – that require power in order to operate. So always check the product specifications first.

As with traditional speakers, dynamic microphones are excellent at handling high volumes with tried and true technology. Not only are dynamic microphones typically less expensive (but not always so) to manufacture (which often makes them more affordable), but the electronic insides tend to be more rugged than their condenser counterparts. This means they can take a hit and handle a drop – ideal for actively holding in hands versus leaving it mounted on a fixed stand. But keep in mind that overall durability comes through quality construction; just because a microphone is a dynamic doesn’t guarantee it’s built to last, let alone outlast a condenser microphone.

Dynamic microphones aren’t as sensitive – for the most part, since there are some expensive models that can deliver incredible results – as condenser microphones. This is largely due to the weight of the magnets and coil, which inhibits how quickly the cone can respond to sound waves (especially high frequencies, since they don't have as much power to move the mass of the diaphragm). While certainly a drawback, depending, it’s not always a bad thing. Lower sensitivity and a more limited high-frequency response generally means less detail captured in recordings, but that also includes ambient/unwanted sounds.

So if you want to cut out most all of the environmental and background noise around you while recording, a dynamic microphone may be the way to go. Also, the relatively slower response of the cone makes dynamic microphones quite adept at capturing forceful, low frequency sounds, such as drums, bass guitar, cello, and so forth. Combined with the ability to handle high volumes, dynamic microphones tend to be the preferred choice for live recording rather than studio recording. On top of all that, the lower sensitivity means dynamic microphones are better at resisting audio feedback loops.

However, many dynamic microphones can add a bit of unintentional coloration (sometimes referred to as warmth) to sounds being recorded. This effect can be significant or minimal, depending on the brand and/or quality of the microphone itself. One may not notice or even care, unless the accuracy of sound is of utmost importance. But in some of those instances, a condenser microphone may be the preferred choice.


  • Does not require external power and/or batteries

  • Easily handles high volume sounds/instruments

  • Typically more affordable (but not always the case)

  • More durable than condenser microphones (usually)

  • Ideal for outdoor/live recording environments


  • Generally requires an additional amplifier (for best results)

  • Not as sensitive/responsive as condenser microphones (especially at higher frequencies)

  • Frequency response can vary greatly depending on design/application

You can relate the operation of condenser microphones to that of an electrostatic speaker, but in reverse. So with an electrostatic speaker, a thin diaphragm is suspended between two grids (also known as stators), which are connected to a voltage supply. The diaphragm is constructed with electrically-conductive materials so that it can hold a fixed charge and interact (attract and repel via electromagnetic fields) with the grids. Audio signals (in the form of electricity) of proportional strength but opposite polarity are sent to each grid – if one grid is pushing the diaphragm, the other grid is pulling with equal strength. As the grids fluctuate from the changes in voltage, the diaphragm moves back and forth, which results in creating the sound waves we can hear. Unlike dynamic microphones, condensers don’t have any magnets.

So in reverse, a condenser microphone picks up sound pressure, which moves the diaphragm’s distance in relation to the grid (known as a back plate for microphones). This interaction between the electromagnetic fields results in changes to the current, which is what translates into the audio output signal. One thing of note is that the fixed charge on the diaphragm is maintained by a capacitor, which means that condenser microphones require external (also known as phantom) power to operate (e.g. through batteries or cables). The power is also necessary for the microphone’s amplification circuitry – the changes in current are too small to be registered by connected equipment unless there is also a built-in amplifier.

As with electrostatic speakers, major benefits of condenser microphones are enhanced sensitivity and response. By design, the thin diaphragm is capable of quickly reacting to faint and/or distant pressures of traveling sound waves. This is a reason why condenser microphones are exceptionally accurate and adept at capturing subtleties with crisp clarity, which makes them ideal for high-fidelity recordings – particularly ones involving vocals and/or higher frequency ranges. And because of how the electronics are designed to work, condenser microphones can be found in a wider variety of shapes and sizes than dynamic microphones.

Although enhanced sensitivity may seem fantastic, there are some drawbacks. Condenser microphones are subject to distortion, such as when attempting to record very loud instruments or sounds. They are also more susceptible to audio feedback – this happens when sound received by the microphone passes through a speaker and gets picked up again by the microphone in a continual loop (resulting in those ear-piercing squeals). They can also pick up on unwanted noise, particularly if you’re not in a very quiet or sound-proofed room. For example, a condenser microphone may not be the best to use for an outdoor interview/recording when there is wind, rain, or city/nature/people sounds in the background. Although such noises can be removed with software for editing music and sound recordings, it does require that extra step.

The electrostatic technology inside condenser microphones tends to make them more fragile and expensive (most often but not always) than dynamic microphones. Unlike the sturdy magnet and coil mechanism of dynamic microphones, the thin diaphragms in condensers are delicate and can end up easily torn or damaged through excessive sound pressure levels (SPL) or physical impact. You definitely want to handle these with care, especially if a replacement condenser microphone could cost you several hundred (or more) dollars. Ever seen someone perform a mic-drop on stage? It probably was a dynamic microphone and not a condenser.


  • Creates strong audio signals without need of a preamp

  • Generally more sensitive to picking up faint and/or distant sounds

  • Greater dynamic frequency response

  • Ideal for indoor/quiet recording environments (usually)


  • Requires external (phantom) power and/or batteries

  • Enhanced sensitivity can lead to distortion in certain situations

  • Can be more expensive (but not always the case)

  • More fragile electronics than that of dynamic microphones

Deciding Between Dynamic and Condenser Microphones

Although both types showcase strengths relating to how they function, there are other aspects to consider if you’re looking for a new or replacement microphone. Many microphones are designed with a specific use in mind, so it’s best to match uses with needs. You might want a microphone that's specialized for: general purpose recording, live performances/events/shows, PA systems, interviews, studio recording, vocals, acoustic instruments, electric instruments, high-frequency instruments, low-mid frequency instruments, flat frequency response, enhanced/tailored frequency response, podcasting/newscasting, and so forth. You can find excellent options with either dynamic or condenser microphones across the many brands.

Also, certain features and specifications can result in leading one type to being more suitable than the other (and vice versa). For example, microphones with larger-sized diaphragms tend to be more accurate/sensitive than ones with smaller diaphragms (size does count in these situations). But a larger diaphragm means a bigger-sized microphone, which will take up more storage space in gear bags or pockets. Some microphones (of any kind) are designed with easy mounting in mind, while others can be a bit more niche. So there can be several trade-offs with whatever you choose.

Microphones also have a varying dynamic range of frequency response (check the manufacturer’s specifications), which can make one type better than another, depending on how they are meant to be used. Some are also designed to treat recordings naturally/neutrally, while others add enhancement – this can be in the form of coloration and/or the perceived size of sound – to the overall imaging. Other specifications to compare and consider are: signal-to-noise ratio, maximum sound pressure level (input sound), ​total harmonic distortion, polar pattern, and sensitivity. In the end, the right microphone will be the one that sounds best to your ears while meeting your needs for use.​

Dynamic Microphones Are Best For:

  • Outdoor use
  • Live performances
  • Gathering news/interviews
  • Recording at high volume levels
  • Lower frequency vocals/instruments (Barry White, bass guitar, cello, tuba, etc.)
  • When you need something durable

Condenser Microphones Are Best For:

  • Indoor use
  • Studio performances
  • Podcasting/newscasting
  • Recording for detail and accuracy
  • Higher frequency vocals/instruments (Mariah Carey, violin, flute, piano, etc.)
  • When durability isn't a factor
