DJI Mic 2, the new best wireless microphone? Full test

After the success of the first version, DJI is back with the DJI Mic 2, a new version of its wireless microphone. So, what does this new edition have in store for us? What new products has the manufacturer come up with? What is it worth? And most importantly, do you have to buy it? All the answers in our full test!

For this new edition, DJI has completely redesigned each of its three components: the transmitter, receiver and recharging box have a new look.

Charging box

Larger than the first version, the charger box has a new, elegant, minimalist design. All-metal, it’s gray in color, with just the latch and indicator lights on the front to announce its battery level when opened, and a raised DJI logo on top. Its appearance inspires solidity and quality.

Inside, nothing changes; it still holds and charges two transmitters and one receiver, as well as USB-C and Lightning adapters. The three devices are automatically paired, which means they are ready for operation at any time.

The transmitter

A new, streamlined design for the transmitters, which are now available in two different colors: ombré black, with its transparent front panel revealing the internal components, and pearly white, an alternative that adds a touch of elegance. The latter is available separately only.

The two models, whose upper parts are reminiscent of the old vintage pickups, are really attractive and well finished. They can be attached to a pocket or belt using the clip on the back, or magnetically using the small magnet supplied. Weighing in at just 28 grams, they’ll barely be felt on a t-shirt or shirt.

A short guided tour of the case:

  • on/off and pairing buttons on one side, with status indicator light on the other
  • the record button and USB-C port for charging and data transfer on the other side
  • connectors for charging via the charging box below
  • the clip on the back

In addition to its new look, the DJI Mic 2 features the following small changes:

  • The LED indicator light has been moved to the side
  • The record button now features an orange circle, making it more easily visible.
  • The mounting clamp now includes a cable grommet (for a lapel microphone cable, for example).
  • The windscreen attachment system has been greatly simplified: simply insert the windscreen into the top of the windscreen.

The receiver

Slightly larger than the V1, the receiver also features a completely new design. Next to the touchscreen, which has grown slightly in size (1.1″), there’s now a small notched thumbwheel. The thumbwheel can also be used to navigate the device’s simple, intuitive menu. Pleasant to use, it can also be pressed to confirm a selection.

A small tour of the 28-gram case:

  • on/off button on one side
  • the two 3.5mm jack ports on the other side: the TRS port for sending sound to the camera (now in orange to identify it at a glance), and the headphone port for live sound feedback
  • on the underside of the device, the USB-C port for charging and data transfer, and connectors for charging via the charging box and for installing USB-C and Lightning adapters

DJI Mic 2: autonomy ⚡

Batteries360mAh (transmitter and receiver)
3250mAh (recharge box)
Autonomy6 hours (transmitter and receiver)
Charging time70 min (transmitter and receiver)
2h40 (charge box)

Another improvement made by DJI on this second edition of the DJI Mic is its autonomy. Whereas the devices in the first version offered between 5 and 5.5 hours of operating time, the receiver and transmitter of the DJI Mic 2 each have a battery life of 6 hours.

With the recharge box fully charged, you can recharge each device twice, bringing the total operating time to a cumulative 18 hours. This is more than enough to ensure that you don’t have to worry about this during a day’s shooting.

Note also that the charging time is 70 minutes for the transmitters and receiver individually, and that the charging box will be at 100% capacity in 2 hours and 40 minutes.

TRS portCameras and camcorders

The DJI Mic 2 can be used in three different ways.

The first option is to connect the receiver to the device you use for filming. This option has the advantage of adding audio directly to the video files you create.

With this method, you can connect a variety of devices:

  • iOS or Android smartphone via Lightning or USB-C adapter
  • a compact or SLR camera, an action camera, or a vlogging camera such as the DJI Pocket 3 via the 3.5mm TRS port or USB-C adapter, depending on your device’s connectors

The second option is one of the great new features of the DJI Mic 2: you can now connect the transmitter via Bluetooth directly to compatible devices, without going through the receiver. This will work with an iOS or Android smartphone, DJI cameras like the Osmo Pocket 3 or Osmo Action 4 action camera, or even a computer.

We were also able to use this connection method with Insta360 cameras. However, this does not work, at least for the moment, with GoPro action cameras.

Finally, the third option is touse the transmitter as a stand-alone microphone and record directly to its built-in 8GB memory (up to 14 hours of 24-bit recording). You will then need to synchronize the audio and video tracks in post-production.

32-bit floating-point recording

This is the other big news: the DJI Mic 2 can record in 32-bit floating point.

What does this mean? Most microphones on the market record in 24-bit. 32-bit is a bit like the raw image format: the microphone records more information , giving us more possibilities and flexibility to improve rendering in post-production.

This is a huge advantage: the microphone will pick up weaker sounds and not saturate on louder ones. If your caller is shouting, you can reduce the higher frequencies in your editing software; if he’s whispering, you can add gain without adding unwanted noise.

A wrong gain setting before a shoot, or an incident like sudden loud noise (which unfortunately happens very often on location), and 32-bit can literally save the day by giving you the flexibility to deal with any unforeseen situation.

Please note, however, that this recording method will not be available if you connect your transmitter via Bluetooth.

Intelligent noise reduction

Another interesting addition by the manufacturer to this new edition is intelligent ambient noise reduction. Triggered by a simple press on the on/off button or the icon on the touchscreen, this function analyzes the sound, then purifies it to bring the voice to the fore.

Even if there are many situations where you want to be able to keep ambient noises in order to preserve the ambience of the place you’re in, it can also be useful to remove them as soon as you record, thanks to this option, when they take too much precedence over the voice.

So how well does it work? Read on in the section dedicated to sound quality to find out what we think of this feature.

Rescue runway

This feature can also save your life in certain situations. The DJI Mic 2 transmitter simultaneously records a second backup track at -6dB. Super handy in case of unexpectedly large audio peaks.

Preset gain

The receiver incorporates a whole range of built-in gain presets to be used according to your camera model. Simply select the make and model of your camera and you’ll automatically get the gain you need to record the sound of your voice in the best possible conditions.

Range

According to the manufacturer’s data, the DJI Mic 2’s transmitter has a range of 250 meters. It should be noted that this range will be reduced to 160 meters in Europe due to current regulations.

Please note that the range will be considerably reduced if you connect your transmitter via Bluetooth. This proximity wireless technology limits the distance to just a few meters, usually between 10 and 15 meters from your device.

DJI Mic 2: sound quality

So let’s take a look at the sound of the DJI Mic 2.

Specially designed to capture voices, this microphone excels in this mission. Sound quality is top-notch, guaranteeing crisp vocals. If you’re used to the built-in microphone on your smartphone or action camera, the DJI Mic 2 will clearly take you to another level.

What about noise reduction? Whether it’s the hustle and bustle of cars, construction work nearby, or the hubbub of a shopping mall crowd… If you’re vlogging or interviewing in these conditions, this function eliminates unwanted noise, ensuring maximum vocal clarity.

Beware, however, that sometimes the rendering can have a slightly robotic or metallic feel, so use it judiciously, when really necessary.

DJI Mic 2 conclusion: should you buy it?

As a content creator, audio quality is crucial. Whether you’re a vlogger or a video production professional, the DJI Mic 2 is an excellent option: easy to use, versatile (suitable for both vlogging and interviews, indoors and out), offering impeccable sound, considerable battery life and ultra-practical recharging thanks to its case.

With some really interesting new features compared to the first version, such as 32-bit floating-point recording, Bluetooth connection and noise reduction, the DJI Mic 2 is shaping up to be an essential reference in the field.

Buy it if…

… You need clear voices (if you’re a vlogger or frequently use interviews in your videos). Quick and easy to use, the versatile DJI Mic 2 works perfectly and is the ideal companion for adding professional-quality sound to your videos. It’ll take you to the next level if you’re still recording with the built-in microphone on your camera or smartphone.

Don’t buy it if…

… you already have the DJI Mic 1. Unless one (or more) of the new functions would be useful to you, the first version already does its job very well, so you already have quality sound in your videos. The DJI Mic 2’s 32-bit floating point offers undeniable security, but if you set the audio gain correctly before shooting, 24-bit will be more than sufficient.
