DJI has launched its new DJI Mic 2 wireless microphone system. One of the big upgrades with the new system is on-board 32-bit float recording.

DJI Mic 2

The DJI Mic 2 wireless microphone system comes with either one or two transmitters and one receiver unit. If you opt for the system with two transmitters, you also get DJI’s charging case included. The case is available as an optional add-on for the single transmitter set. In addition, the transmitters feature a clip-on design with a magnetic snap for easy attachment to clothing. You can use the transmitters’ built-in microphones, or you can plug in optional lavalier mics instead.


The DJI Mic 2 receiver unit features USB-C and Lightning digital outputs. It also has a 3.5 mm TRS analog output for use with your camera or separate audio recorder. All of these options mean that the DJI Mic is compatible with cameras, computers, tablets and iPhone or Android smartphones. In addition, the receiver has a dedicated 3.5 mm TRS monitoring port for real-time audio monitoring. Without the receiver, the transmitters can connect directly to DJI’s Osmo Pocket 3 or Osmo Action 4 via Bluetooth.

32-bit float

Each of the DJI Mic 2 transmitter units has 8 GB of internal storage. This means that you can record up to 14 hours of uncompressed 48 kHz 24-bit audio. This is great as a backup in case you lose your wireless connection. You can also use the transmitters as standalone audio recorders. In addition, the transmitters support 32-bit float internal recording for up to 11 hours. 32-bit float recording has a very high dynamic range, so you don’t need to worry about sudden changes in sound level.

Using the DJI Mic 2

DJI Mic 2 automatically powers on as you open the charging case. This smart case also automatically pairs the receiver and transmitters while charging them. This means you can start recording as soon as you open the case. DJI says that the microphone has a maximum audio transmission range of 820 feet (250 meters) in open, unobstructed environments without interference. This is an impressive distance, though in practice you may find that you lose signal sooner than this.

Other features

The DJI Mic 2 features intelligent noise canceling so you can record clear audio even in a busy environment. You can also opt to record a second safety track -6 dB alongside your main audio track to safeguard against spikes in sound levels. The receiver unit has a 1.1-inch OLED touchscreen and a control dial to adjust settings including gain, volume and brightness. In addition, the screen gives you information such as volume and battery level. The transmitters even feature a built-in motor to send haptic feedback during key operations.

Battery life

The transmitters and receiver have a battery life of up to six hours per charge. With the charging case you can extend the usage time up to 18 hours. When you are using a smartphone, the receiver’s USB-C port can also connect to a charging cable to charge both the phone and receiver.

What we think

The DJI Mic 2 is a big upgrade on the company’s original DJI Mic wireless system. Longer battery life (up to 18 hours compared to 15 with the previous model) is always welcome. However, the 32-bit float on-board recording is the biggest new feature. In addition, the direct Bluetooth connection option is useful if you have a compatible device. If you are looking for a new easy-to-use wireless microphone system, then the DJI Mic 2 is one to consider. It’s also $50 cheaper than Rode’s Wireless Pro, although that system does include lavalier mics, which are an extra purchase for the DJI Mic 2.

Pricing and availability

The DJI Mic 2 is available to order from and authorized retail partners now.

The DJI Mic 2 system with two transmitters, one receiver and a charging case retails for $349. This also comes with two windscreens, two magnetic clips and a charging cable. In addition, you get a 3.5 mm TRS audio cable and adaptors for Type-C and Lightning mobile phones.

The DJI Mic 2 system with a single transmitter and receiver costs $219 but you don’t get the charging case. The case is available separately for $69 and the DJI Lavalier Mic is $39.
