Buying the best boundary microphone will benefit your audio capturing in many ways, especially if you’re in need of some certain applications, such as conferences, churches, meetings, desktops, specific instruments and more. They’re not necessarily the most “popular” type of mic (although the internal build is since it’s technically a condenser microphone, more particularly small-diaphragm); however, if you feel a boundary mic is something you’ll benefit from, you’ve come to the right place. There are some amazing models out there to look at, so we compiled a list below to give you the options of the best boundary microphones in the market today.
What are boundary microphones?
To review for a little bit before we get int our picks, a boundary microphone is a small diaphragm condenser microphone with a twist — it’s capsule and internal circuits are mounted into a housing to lay on or be attached to a flat surface. They typically fit in the palm of your hand and can record great distances, usually with a cardioid or super-cardioid polar pattern. So why would anybody need to have a microphone solution such as this? What are the benefits of laying on a surface flat?
These boundary mics are used for picking up rooms with multiple audio sources. The flat surface (as in wall, table, or ceiling) is ideal because the boundary mic is made specifically to pick up sound that is reflected off the surface it’s on. Think of any time you need to pick up sound from an entire room, such as business meetings, but we’ve also seen them in various other applications such as pianos, sports (like hockey boards for body check sound effects), small musical ensembles with room acoustics, and more.
The best boundary microphones
Audio-Technica Pro 44
Let us start this list with a multifaceted condenser microphone that is perfect for applications with low required visibility. Coming from one of our favorite brands ever, the Audio-Technica Pro 44 provides a rocky design and construction, creating a more durable microphone which will also enable it to have longevity as a long-term investment. The Pro 44 notably comes with a 25’ detachable cable that gives the artist a little bit more breathing room and ability to move around. This is a microphone with so many great features, but what truly makes it one of the best boundary mics available is the combination of audio quality as well its ability to be positioned it whatever manner you desire.
This creates various specific advantages, including the enhancement of its signal-to-noise ratio, as well as an increased suppression of ambient noise. There is little reason to question the price tag of this mic (it sits in the middle price-point), as it features so many high-quality elements. It’s safe to say that Audio-Technica has once again created another superb product in the Pro 44.
This higher-end model is for those wanted something a bit better in overall build and quality, and if you have the cash this one is without a doubt one of the best boundary microphones for various reasons. To start, how can we not mention the microphones high sensitivity, and ability to handle large amounts of distance. The Audix ADX60 is going to amplify your sound so well that people will be able to hear your voice and instruments at a highly increased range. This is a great boundary mic choice if you are in the music industry, speaking on a large stage, or even speaking in a business conference.
The mic itself requires a 9-52V phantom power for its operational use and it also comes with a 25’ cable and phantom power adapter. The ADX60 is an optimally designed condenser microphone that is going to without a doubt be easy to position, and also durable enough to withstand an increased amount of usage.

The CAD U7 is the next boundary mic on our list and is another great little condenser microphone that is engineered to help articulate your speech in the way that you desire. The true beauty in the U7 is it’s ability to capture speech, which is so often important in conferences or business meetings. The microphones frequency response is more than adequately designed to capture and deliver your voice so that others know exactly what it is you’re saying, so we don’t recommend this one for any instruments if that’s what you were planning on using your boundary mic for.
There is not much to complain about with CAD’s U7 as it comes with all the necessities, including a 10’ USB cable, an omnidirectional pickup pattern so that you can absorb frequencies from all directions. It’s quite budget-friendly (lower than both of the previous models listed), so if you’re looking for an affordable boundary mic to deliver your speech, CAD has got you covered.
The Shure MX391 is truly one of the boundary microphones hidden gems, and it isn’t because of how much we love the brand. This flat frequency responsive mic comes with an abundant number of intriguing features that make it a pick as one of the best boundary microphones on the market. When thinking about your boundary microphone a feature that is often overlooked, yet incredibly underrated is the range, or lack thereof when it comes to the sound.

This mic contains a bass-tilt switch that enables the user to adjust its low-end response to whatever application that aligns with it, allowing for more custom tweaking depending on your mood or particular application that day. PCC standing for Phrase Coherent Cardioid, (it’s actually made by AKG, a brand you may be familiar with) which is an enhanced technology that uses tiny diaphragms creating a frequency quite smooth so you will be free of any issues that deal with phase interference. The mic’s polar pattern is a super cardioid which is optimal for picking up a specific source in front of it.
The beauty of the supercardiod is that it is essentially going to eliminate all displeasing noise from its surroundings. The best way to describe the PCC-160 is “multitalented.” When it comes to adaptability, while sustaining the same polished sound, the PCC-160 fits each and every need.

The microphone is a miniature cardioid condenser boundary microphone that is not going to come across as too flashy or too obvious when it comes to its appearance in the room.
