If the thought of getting the best boundary microphone ever crossed your mind, then you’re at the right place.
Of course, this is a review of the best-rated boundary microphone. Still, it’s a bit foolish to jump into something you may not have any clear idea about.
So, what is a boundary microphone?
Well, you need these microphones if you want absolutely no intrusions.
Unlike the various types of microphones, the boundary microphones have no stands. They are pretty much condenser microphones with either cardioid or super-cardioid polar pattern. But there are obvious differences there as well.
Also, the diaphragm is mostly small for these options.
These microphones have mounting points just a couple of feet away from the source. It can be either be the ceiling or the floor. Or it can be some other mounting point.
And boundary microphones don’t need any comb filtering, which doesn’t have that great of a fidelity.
Now comes the question of finding out the right options.
Well, we obviously took that responsibility. So, here are your choices for the best value boundary microphones.

How to Buy a Boundary Microphone: Knowing the Right Things
Things should be pretty clear by now if you’re on the hunt for the best boundary microphone. We also have a strong belief that many of you have already chosen an option.
But there are those of you out there who are keen to try out their luck. They want to try something different.
And that’s perfectly fine. The sign of a true professional is to experiment with different options (you could start by experimenting with one of our recommendations!). But you’d make a fool of yourself if you don’t know the things that matter.
Here is a list of things that will help you buy the right microphone.
We’re well aware that this review is about boundary microphones. But what we are about to talk to you about will make a difference on whatever mic you want to buy.
The Brand Value: A Necessity
If you’re someone with a decent budget and don’t want any compromises, then a proper brand will come to your aid.
Brand value is an important weighing factor whenever you’re looking for a microphone.
The best brands always offer the best services. They don’t just offer quality products. As a matter of fact, they stand by their products and are committed to helping the customers in any way possible.
So not only are you getting a boost of confidence in getting the right microphone, but you’re also purchasing the reliability with it.
Here is a list of some popular microphone brands out there (in no particular order):
- Rode Microphones
- Blue Microphones
- MXL etc.
The Pricing: A Forethought
No matter what anyone tells you-pricing matters.
You could buy a decent microphone for less than 40 dollars. The pricing can go up to 200+ dollars.
One of the simple rules of thumb is to simply plan on a price point (we did say it a lot of times). This will eliminate unnecessary options. From there, you could weigh the features and move on from there.
The Feature Set: How Do you Make a Decision
There are a lot of factors involved in the feature set.
There are two things: the features you need and the features you don’t need. But before you can even start with the breaking of features, you need to have a clear idea about the following:
You need to have a clear idea about how you’re going to use your microphone. There are certain scenarios:
You could be using it for a board room meeting (the main use case for a boundary microphone). Or you could use it for recording vocals for your stream.
Both of these use cases have specific needs. So, you may want to look at the features of the options you have in your mind.
There is also the studio purpose, which often requires ambient mic placement. The feature set you need for that purpose is entirely different and requires special attention, you get the idea.
The Pickup Pattern
Depending on the application, you need to find the right microphone with the right polar pattern.
For instance, the board meeting and the streaming microphones pretty much have a unidirectional or cardioid polar pattern. These are either condense or dynamic microphones. You now have to choose an option that suits you.
And if you’re going for studio operation, then an omnidirectional polar pattern may be highly suitable for you. Studio production often requires the presence of an ambient environment.
The Frequency Response and Sample Rate
Whatever brand you choose to go with, make sure it can respond to a wider frequency range. There are brands out there that are doing a really good job of making sure their microphones can respond to wider frequency ranges.
And the sample rate needs to be proper as well. Anything below 24-kHz isn’t an acceptable range. If you want clear audio, then you must be willing to shed a couple of bucks in favor of a better sample rating.
And there is the matter of Sound Pressure Level or SPL, which needs addressing as well. In general, the reference is 0.5% distortion at 1-kHz.
You should always pay special attention to the number of accessories you are getting, especially if you’re paying a premium.
So, before making the final purchase, make sure to check if there’s anything extra. Considerations like these always bear fruit.
Q: What are the possible use cases for a boundary microphone?
Ans.: There are a lot of things you can do with a boundary microphone:
- You can use a boundary microphone to record the complete audio within a room.
- You can use it as a piano microphone.
- You can use it as media for body check audio.
Apart from these three, there are other use cases out there.
Q: What exactly is a cardioid microphone?
Ans.: A cardioid microphone has a sound pickup pattern that’s almost the shape of a heart. In short, the sensitivity has the distinct shape of a heart.
A cardioid microphone is only capable of picking up noise from a certain side. You can call it one-sided or unidirectional, as the sound pickup is only limited to one side only. This allows for better sound isolation, which is often a requirement for vocals.
Q: When would you need an omnidirectional microphone?
Ans.: An omnidirectional microphone is capable of capturing sound from the surroundings. And that’s also one of its main disadvantages.
If you’re focusing on a particular scenario where only the vocalist needs picking, then an omnidirectional microphone may not be the wisest choice. Although it is picking up the noise, it’s picking it up from all directions. And that’s when the problems occur, as there is a noticeable amount of background noise.
Q: Is there a way to test the polarity of a microphone?
Ans.: It’s very simple really. All you have to do is put a probe on the outer shell and another probe on either of the two terminals of the microphone. If the multimeter gives you a beep back, then you’re on the negative terminal.
The above-mentioned method is a popular way of making sure which terminal you’re on.
Q: Is there a way to check the microphone?
Ans.: If you mean if the microphone is working correctly or not, then yes, there is.
All you have to do is select the ‘Do nothing’ button on the radio button (depending on your gear, steps may vary). Then once you restart your system, you need to check the recording panel to see if the bars are swinging or not. If they are not swinging, you have a problem with your setup.
Otherwise, all is hunky-dory!
Q: Is there a difference between cardioid and super-cardioid pickup pattern?
Ans.: There is a slight distinction.
The super-cardioid polar pattern is tighter than the cardioid pickup. In simple terms, it has better rejection capabilities from the sides. So, it only picks up what’s directly at the front. Anything else gets rejected.
Q: What is the proper way to place mics for recording piano audio?
Ans.: All you need to do is put two boundary condenser microphones at three strategic positions. One should be 3-feet in front of the piano in either X or Y position. Another needs to be 5-feet from the ground.
Q: What things should you keep in mind for piano recording?
Ans.: There are certain things you need to keep in mind:
- The place has to be roomy enough for a proper flow of audio.
- The microphone diaphragm needs to be fragile enough.
- The lid of the piano should be open for a fuller audio signature.
- One microphone should be close to the string and the other one should place at a decent distance to cancel out any ambiance artifacts.
- The mic that’s further away should have a minimum 3-time distance from the closest microphone.
Q: What do you mean by the XY placement?
Ans.: It’s a simple measure of putting two microphones as close as possible to each other. Their diaphragms shouldn’t touch. But they have to be as close as possible.
Q: Is there something called ‘ambient mic placement’?
Ans.: Ambient mic placement is the practice of covering the entire sound of the room rather than the audio source. If you want a natural setup, then this type of placement can come in handy.
If you’ve made it this far, then congratulations, you’ve taken a whole lot of information. It’s clearly going to help you buy the best boundary microphone.
But there are those of you out there who still aren’t convinced. You still don’t know which boundary microphone brand is better.
In a perfectly sound world, we would ask you to go with one of our options (we are still doing so!). But if you want to try out your luck, you may want to go through the buying guide and the FAQ section. Both of these sections have specific designs to help you out.
But, if you don’t want to go through all the trouble, then you should go for the best brand that’s out there. Ask your friends, take some advice from your fellow professionals. That should give you a nice starting ground.
And that’s pretty much all we have to say right now. We hope you find our efforts useful.
