DJI’s busy engineering team is at it again with the creation of the company’s third wireless mic system in less than two years. The new flagship DJI Mic 3 has a wholesale design change from the Mic 2 plus numerous improvements in areas like sound quality, noise reduction and the number of subjects you can record at once — though there is one downgrade compared to to the last model. I’ve had one for over a week so I’ll provide some impressions as well.
The most noticeable change with the Mic 3 is the smaller transmitter size and lighter weight. It weighs just 16 grams (.58 ounces) compared to 28 grams (.99 ounces) for the Mic 2, though it’s bigger and heavier than the Mic Mini transmitter (10 grams). DJI has also improved the transmitter mounting options, introducing a rotating clip along with the magnetic option. There’s even a choice of five colors for the windscreen to better match your subject’s clothing.
The smaller size and rotating clip makes the Mic 3 more discreet and easier to attach to any shirt or hat. However, there’s still a large “DJI” logo on both sides of the transmitter that looks ugly but gives the company free advertising, I suppose.
The charging case holds a receiver and two transmitters and, unlike the last model, now lets you insert the transmitter with the magnetic mount and windscreen still attached. Fully charged transmitters can run for about eight hours and the receiver can go 10 hours. However, the case provides enough power to charge all three devices 2.4 times for about 28 hours of extended use. This feature makes the Mic 3 useful for marathon shoots and was key to the success of the original DJI Mic, though competitors like Sennheiser have caught on and introduced similar cases.
The Mic 3 now supports up to four transmitters and eight receivers at once. That means you can record four subjects at a time to as many as eight receivers simultaneously for multi-camera shoots (if you purchase the extra kits, of course). I wasn’t able to test this feature as I had just a single kit, but it’ll be handy for large jobs if it works as advertised.
To make syncing and lining up all that audio and video simpler, the Mic 3 now offers high-precision timecode capture embedded during internal recording. I tested this feature with two cameras, and once I figured out how to align the shots in DaVinci Resolve, it proved to be a valuable post-production timesaver.
The receiver can also be set to quadrophonic mode for select Sony cameras and software, allowing independent output of four channels at once to a single camera. DJI is promising a range of 400 meters (around 1,300 feet) and strong resistance to interference via automatic frequency hopping between the 2.4GHz and 5GHz bands.
There are some major improvements in audio quality as well. It’s DJI’s first microphone with two adaptive gain control modes. For noisy outdoor environments like sporting events, Automatic mode suppresses sudden volume spikes to prevent clipping. Dynamic mode, meanwhile, adjusts gain on the fly in response to volume changes to ensure consistent loudness in quieter settings like studios.
I tested this feature in Paris in a relatively quiet studio and outside with traffic and other city noises. The Automatic setting did a good job suppressing those unwanted sounds without a noticeable impact on audio quality. And the dynamic mode kept my speaking levels steady even when I trailed off at the end of sentences, again without impacting voice timbre or clarity.
The Mic 3 is also DJI’s first with three tone presets (Regular, Rich and Bright) to handle different voice characteristics (medium, low and high pitches). This feature also worked as advertised. Set to “Regular,” I needed less equalization than usual to even out my voice and it worked equally well on a higher-pitched female voice.
Two-level active noise cancelation reduces background sounds like air conditioning and wind noise. Again, this worked effectively, though like any noise reduction algorithm, it impacted voice quality by artificially reducing some frequencies. Finally, the lossless audio feature lets the mic send uncompressed 48kHz 24-bit audio directly to the receiver to eliminate any MPEG audio artifacts. This is likely overkill for most use cases. While the Mic 3 offers good sound quality, it’s nowhere close to a dedicated high-end studio microphone — so you’ll be hard pressed to notice any difference.
DJI also added internal dual-file 24-bit and 32-bit float recording, which records the highest quality possible without any clipping. That allows you to capture two files of 32-bit float sound without algorithmic changes, two channels of 24-bit sound with algorithmic changes or one of each. That’s an improvement over the Mic 2, which only captured a single file of the original sound internally in 32-bit float.
There’s one key feature missing on DJI’s Mic 3 that might make it a non-starter for some audio pros. Unlike the Mic 2, the transmitter lacks a 3.5mm mic port for wired lav or other microphones. That means you’re relying on the Mic 3’s built in microphone, and although it offers high quality sound, may not be high enough for applications like broadcast.
Finally, the Mic 3 works with DJI’s OsmoAudio system, so it pairs with the Osmo 360, Osmo Action 5 Pro, Action 4 and Osmo Pocket without the need for a receiver. I tested it with the Osmo 360 and Action 5 Pro and it connected without any issues. For other devices, you can wire it in via a 3.5mm TRS port, TRRS monitoring and a USB-C port, or to smartphones via Bluetooth or USB-C using the included adapter.
DJI’s Mic 3 is now on sale in most territories, priced at $329 in a kit with a charging case plus two transmitters and a receiver, or $219 with a single transmitter and receiver.
Update, August 28, 2025, 9:45AM ET: This story was updated with US sales links. DJI originally said the Mic 3 wasn’t available in the US yet, but the company changed course and the new product can be purchased from DJI or Amazon.
