Best Condenser Mic Under 300 Dollars in 2019

This buying guide was written to help you make an informed choice in your search for the best condenser mic under 300 dollars. These special microphones are designed to capture the voice of a live vocalist or the instrument of a musician as flawlessly as possible. They transform sound into a piece of data that the mix engineer can then manipulate.

With so many great condenser mics on the market, it can be difficult to make a confident decision. Condenser mics are the Holy Grail of the modern recording studio. Everyone wants the best of the best. Part of the challenge of buying professional audio gear is balancing the price with the utility and quality. And we always must keep in mind our specific needs and the law of diminishing returns – after a certain point, any further increase in price only brings us smaller and smaller increases in quality.

Best Condenser Mic Under 300 Dollars: The Bottom Line

The “best” mic will ultimately be the one that best suits your specific needs. Many mics will have their strengths and weakness in different areas, so it’s important to consider the functionality of the mic that’s right for you. If you’re looking for more information on functional uses, scroll on down to the section called The Makings of the Best Condenser Mic Under 300 Dollars. If you’re ready, here are the top 3. After a load of research and hours scouring reviews, I recommend the post-2014 version of the Rode NT1.

Top Pick: Rode NT1 (post-2014)

The Rode NT1 wins top spot in our list due to it’s insanely low self noise, at 4.5 dB. This is the lowest on our list, and would make a great first time mic purchase for someone looking to record vocals. You can even score the shock mount and pop screen in the kit they offer, all for under 300 bucks.

Runner-up: CAD Audio Equitek M179

Second place goes the the CAD Audio Equitek M179, due to it’s flexibility with polar patterns. While it’s not as well suited for vocals, it does have the versatility to handle drums, guitar, and many other instruments with ease.

Also Great: Shure KSM137

The KSM137 comes in third due to its superior transient response and extreme 170 dB SPL loudness capacity. This makes it great for things like guitar cabinets, stringed instruments, drums, and very loud sounds in general.

The Makings of the Best Condenser Mic Under 300 Dollars

Before we get into the list of the best condenser mics under 300 dollars, it’s important to know what to look for when shopping for one. The following items will outline materials of construction and design choices that make the sub-$300 condenser mics in our list some of the best out there, both in general and for your specific needs.

Condenser Mic Capsule

The capsule is arguably the most important part of the condenser microphone. This is where the magical conversion from pressure waves in the air (also known as sound) to electricity occurs. How does this happen, you ask? Well, it’s actually pretty simple.

The capsule consists of two main components. The first is a very thin sheet of conductive material called the diaphragm. The second is a metal backplate. The two are mounted in close proximity to each other. They act like a capacitor, and when the thin, sensitive diaphragm vibrates due to it’s exposure to sound pressure, the capacitance between the two varies and generates an electrical waveform.

When shopping for the best condenser mic under 300 dollars, we need to be critical of the capsule in the following ways, and think about how changes in some of these things will effect the functionality and uses of the microphone.

  1. Diaphragm mass & size
  2. Diaphragm materials & durability
  3. Polarization method

Diaphragm Mass & Size

The size of the diaphragm, and more specifically the diameter, is crucial to consider for what the mic will be used for. There is no “best” diaphragm size, only the best size for your needs.

Most manufacturers refer to their mics as “large diaphragm” or “small diaphragm” where, as a rule of thumb, large means a diameter of 1 inch or greater and small means a diameter of 1/2 inch or less. This rule can vary from manufacturer to manufacturer.

In general, large-diaphragm mics are great for vocals and bass drums or other low-frequency instruments. They are less consistent when it comes to pickup patterns across the frequency spectrum, but this can also be what makes them unique. Each one has it’s own character.

In general, small-diaphragm mics are considered technically superior (and usually more expensive) when it comes to the raw accuracy of capturing audio. This is due to the smaller mass of the diaphragm, which makes it very responsive to sound waves in the air. For this reason they, are very versatile and can be used to record pretty much anything.

Diaphragm Materials & Durability

The materials used are very important! Considering that the the potential “atmosphere” the mic will be exposed to (the vocalist’s breath) will contain moisture and possibly even particulate matter, quality condenser mics will use materials that are highly resistant to corrosion and moisture over time.

For this, many high quality condenser mics will use gold-sputtered Mylar for the diaphragm. Gold is both extremely conductive and corrosion resistant, which is why you’ll also find it used in XLR cable contacts, and other electronic components like circuit boards and Mark Zuckerberg’s brain.

Go for the gold, baby!

Sputtering is a manufacturing process where they spray a thin layer of gold atoms on the Mylar diaphragm. This makes it much more conductive while still maintaining its flexibility and ability to move with the sound waves.

Polarization Method

The capsule must be electrically charged, or polarized, for it to work. This can be achieved in two ways:

  1. Electret design – the backplate, diaphragm, or inside surface is made of a permanently polarized (charged) material. Diaphragm electrets are not ideal for pro audio because they change the material properties of the diaphragm in a negative way.
  2. Externally polarized with 48 V phantom power

In the past, electret mics were considered inferior due to their loss of charge over time. Now, technology has progressed to where backplate electrets are on par with “true” externally polarized condensers.

Polar Patterns

You may have heard the term “polar pattern” mentioned in your search. A mics polar pattern is its sensitivity as a function of circumferential position around the mic. A “cardioid” condenser mic is referring to it’s polar pattern. A cardiod is basically a heart-shaped graph when plotted in 2D… I can almost feel the love.

best condenser mic under 300 dollars cardioid polar pattern

From Wikipedia, with love.

If the microphones capsule is faced to the left and located at the intersection of X and Y axes, and it has a cardioid pickup pattern like shown above, this means it will be most sensitive to sound coming from the left side, and much less sensitive to sound coming from the right side.

Think of it like this – the further the red curve is away from the intersection of axes (origin 0,0 – pink dot), the more sensitive the mic will be when recording sound coming from that spot or general direction. Clear as mud? The video below will help.

As we can see, it’s important to consider what polar pattern you will use depending on your application. Again, as with many of these “best” audio gear buying guides, the best choice will be what suits your specific needs.

There is no best condenser mic for everything (well maybe, but you’ll have to fork over the cash). The best condenser mic under 300 dollars for recording vocals will be a different mic than the best condenser mic under 300 dollars for recording acoustic guitar, although many are very good at multiple things. When considering your purchase, make sure you keep in mind the mics primary function.

Signal-to-Noise Ratio (SNR)

We already know that mics produce an electrical signal. On top of that, all mics will pick up a certain degree of background noise and internal noise due to the circuitry. The noise floor is a jagged line encompassing all frequencies that extends across the frequency spectrum. When a mic produces an electrical signal, the signal will rise up out of the noise to a certain level.

The difference between the noise floor and the signal peak level is called SNR or signal-to-noise ratio. It is expressed in decibels dB. This metric is similar to dynamic range in that it is the difference between two signal levels. The higher the SNR, the less noisy the mic will be – and unwanted noise is never a good thing.

Sound Pressure Level

Maximum sound pressure level (SPL) is a measure of how loud of a sound the mic can handle in dB SPL. Mics with very high max SPL are better suited for drums and other loud instruments like guitar cabinets and brass. Higher max SPL means more versatility in what you can and cannot record with the mic.


  1. Choose a mic with a gold-sputtered diaphragm – this is pretty much industry standard at this point
  2. In general, large-diaphragm condenser mics are great for vocals and bass drums or bass-heavy instruments
  3. In general, small-diaphragm condenser mics are great for live instruments, symphonies, choirs, orchestras, etc.
  4. Consider the pickup pattern:
    1. Omnidirectional – Capture sound from all directions, great for recording in live venues that have good acoustic properties to them
    2. Cardioid – Most common, only captures audio from the front. These are used when you need to focus in on one sound source like a single vocalist or instrument
    3. Super/Hypercardioid – These can focus even more on a single sound, but there is a tradeoff. They are more sensitive from behind.
    4. Bidirectional (Figure 8) – These only capture audio from two opposing sides, and reject sound from the other two. Use these for recording two instruments, or an instrument and voice. Can be used to capture stereo audio as well.
  5. A mic with a high SNR (signal-to-noise ratio) is technically superior. This ultimately means noise will be less present in your audio
  6. A mic with a high max SPL is more versatile – you can record louder sounds with a higher max SPL.

These factors along with the prices were taken into consideration while formulating this list of the best condenser mics under 300 dollars. Have a look!

Best Condenser Mic Under 300 Dollars in 2019 List

Rode NT1 (post-2014)

Rode NT1


The Rode NT1 wins top spot in our list for several reasons. This mic is the quietest in terms of signal-to-noise of any mic in this price range. The self noise is 4.5 dBA due to advanced circuitry and a capsule that is mounted on a special suspension system.
