DJI Mic 3: The Mic I Grab When I’m Getting Paid
My third DJI product and my main mic. Here's what the magnets, the touchscreen receiver and the noise cancellation actually do.
The DJI Mic 3 is worth buying if you’re a content creator whose audio has to be right the first time. Two transmitters, one touchscreen receiver, and noise cancellation that doesn’t hollow your voice out into a tunnel. It’s my main mic whenever a video has my reputation on it. Buy it.

How this review was made: written from my own video review of this product. Every opinion here is my own, from using it myself.
Quick Verdict
I walked through leaves kicking them around with a car driving past, noise cancellation off, and you can still barely hear it. This is my third DJI product and there’s a reason I keep coming back. Buy it if your audio has to be right the first time.
Buy if you:
- Get paid for video work and can’t risk the audio
- Shoot outdoors with wind, lawn mowers and planes overhead
- Record interviews and need two people mic’d at once
- Hate how other lav mics thin your voice out
Skip if you:
- Expect to drive the touchscreen with your fingers; the text is small and hard to pinpoint, so you end up using the knob
- Only ever film indoors at a desk where noise cancellation stays off anyway
- Want the cheapest clip-on mic that works, not the upgrade one

The Case Tells You the Battery Before You Open Anything
I clicked the case open and there it was: battery levels for both transmitters and the receiver, right on the inside of the lid. There’s also an LCD on the front of the hard shell telling you how much charge the case itself is holding. That means you never have to wonder. For a mic wireless microphone you’re grabbing five minutes before a shoot, that’s the detail I notice most.
One USB-C port on the back of the hard case charges all three units at once, transmitters and receiver together, no extra cables.
A Lot of People Don’t Realize the Receiver Is a Touchscreen
The receiver is a full touchscreen, most buyers don’t discover this until they unbox it. Noise cancellation, the voice presets, gain, all of it lives right there on the little screen. You’re not digging through an app to change your sound.
There’s also a turn knob on the side. I use it more than the screen, because the text on that display is really kind of small and it’s hard to pinpoint exactly what you’re tapping. Turn to scroll, press the knob to select, scoot back up to exit. That’s the whole menu system.
Where Other Lav Mics Lose and DJI Wins
Fullness. That’s the gap. A lot of the other lavalier mics, even the good-sounding ones, are lacking a little bit of that lower end. They do mids and highs really well, but when you need actual depth on the voice, they don’t do it. The DJI does.
Then there’s the noise cancellation, which is the bigger separator. My biggest complaint with most mic wireless systems is that their noise cancellation cuts the background noise, sure, but it also shrinks the sound around the person so hard it sounds like they’re in the Grand Canyon. That weird tinny echo. DJI’s doesn’t do that. It cuts noise without putting you in a tunnel, and that’s the reason I keep returning back to DJI on my third product from them.
Setting It Up Took About a Minute
Pull a transmitter out of the case and it’s already connected. Levels start moving on the receiver monitor immediately, no pairing dance. Standard size clip on the transmitter, little light on the side to show you it’s live.
The magnets are the part I’d actually pay for. Instead of clipping and clinching the transmitter onto your shirt and bunching the fabric, you put the magnet behind the shirt and it holds. These are powerful magnets, and I tried to hold two apart in my hands and they fought me. The case has magnetized slots up top so they store themselves. I love the magnet stuff.
The transmitter itself is quite a bit smaller than the older DJI versions, which were more bulky. Same functionality, less of it sitting on me.
Walking Through Leaves With Nothing Turned On
I took it outside on the literal out-of-the-box setting. No presets, no noise cancellation, and no wind cover on the transmitter, straight raw mic. Then I walked through a pile of leaves kicking them around and banging on stuff on purpose to feed it junk.
You can hear the leaves. That’s the point. Then I double-clicked the power button to flip noise cancellation on, kicked the same leaves, and the difference is loud. Not subtle. A car drove past while cancellation was still off and you can barely hear it in the recording.
For me, whenever I’m inside doing standard content creation in the house, my noise cancellation isn’t on. Outside is different. You’ve got wind, lawn mowers, planes, sometimes random animals. That’s where I turn it on and that’s where this system stops wind from ruining takes.
The Second Transmitter Is a Battery Backup, Not a Gimmick
Two transmitters means two people can be mic’d for an interview off one receiver. That’s the headline use. For me, I’m lonely, I have no friends to talk to, so mine is the backup for whenever the first one runs out of battery. Frankly, it isn’t very often.
The transmitters also record internally. Press the button and the audio gets captured on the transmitter on top of whatever your phone or camera is recording. Nice safety net, and it works fine as an audio-only setup if you’re not shooting video at all.
What the Money Buys You
This is the upgrade mic, and I’m not going to pretend otherwise. I’ve got three mics in total and this is the one I go for when I’m being paid for a job or when a video has my reputation on it as a creator. Cheaper clip-on options exist and they’ll get you usable audio.
What you’re paying for here is not having to fix anything afterward. Full low end, noise cancellation that doesn’t hollow you out, a backup recording running in the transmitter, and a case that charges everything and shows you the levels. It’s currently sitting #45 in Musical Instruments on Amazon with north of 4,000 bought in the last month, so plenty of people reached the same conclusion. Worth knowing: it’s running a little above its typical price from the past three months right now, so check the current price before you commit.
Living With It Day to Day
Everything charges in one place. Transmitters and receiver drop into the hard case, USB in the back, done. No separate cables, no hunting for a dongle.
The wind covers are the one consumable-ish thing, and there are several of them in the box. The magnets stow in the magnetized top slots instead of rattling loose in a bag. The soft case handles travel.
Who This Is For
If you shoot outside a treated room, parking lots, parks, someone else’s office, this is the mic that stops audio from being the reason you reshoot. Interviewers and podcasters get a real second use out of the two-transmitter setup instead of paying for hardware they never touch.
If you’re filming casually at a desk indoors and you never touch noise cancellation, you’re buying headroom you won’t use. That’s fine, just know it. For everyone else, the DJI Mic 3 is the one to buy.
Pros
- Keeps the sound full, including the low end most lav mics miss
- Noise cancellation that doesn’t add tinny tunnel echo
- Strong magnets so you don’t bunch your shirt with a clip
- Battery levels for all three units visible inside the case
- Internal recording on the transmitters as a backup take
Cons
- Touchscreen text is small and hard to pinpoint; I default to the knob
- Second transmitter is dead weight if you always film solo
- Priced as an upgrade mic, not a first mic
Frequently Asked Questions
Does it work with an iPhone and a camera, or do I need an adapter?
It’s built for iPhone, Android and camera use, so it covers the three main setups creators run. The receiver is what connects to your device, and the transmitters stay on you.
Do I need an app or subscription to change settings?
No. Every setting I use lives on the receiver’s touchscreen, including noise cancellation, voice presets and gain. No account, no fee, no phone required.
Can I pair more than two transmitters to one receiver?
Yes, the receiver pairs with up to 4 transmitters and can sync to 7 additional receivers, with four-channel output. That’s a podcast table, not just a two-person interview.
What happens if the audio clips or I blow out a take?
The transmitters record internally in dual-file 32-bit float, which is the whole reason that format exists. You pull the backup file off the transmitter and recover the take instead of reshooting.
Do I need the wind covers on for outdoor shooting?
Not always. I ran my whole outdoor test without one and it held up fine, including with a car passing. If you’re in actual wind, put one on; there are several in the box.
