The basic connection process

The DJI Mic connects to your Osmo Pocket 3 through the gimbal's USB-C port using a USB-C to USB-C cable or the DJI Mic's dedicated receiver module. The Osmo Pocket 3 does not have built-in wireless connectivity for the DJI Mic — you must use a physical connection. The receiver (the small box that comes in the DJI Mic kit) plugs into the Osmo Pocket 3's USB-C port on the bottom of the gimbal, and the transmitter clips to your shirt or holds in your hand to capture audio.

Before you connect anything, make sure your Osmo Pocket 3 is powered off. Insert the USB-C connector from the DJI Mic receiver into the USB-C port on the bottom of the gimbal. The port is located directly beneath the screen, next to where the battery slides in. Once connected, power on the Osmo Pocket 3 and open the DJI Mimo app on your phone — the app will recognize the microphone automatically and route audio through it.

The DJI Mic transmitter and receiver pair automatically out of the box, so you do not need to manually sync them. If you are using multiple transmitters or replacing a unit, hold the pairing button on the receiver for three seconds until the LED blinks rapidly, then hold the pairing button on the transmitter for three seconds. They will pair within a few seconds.

Key Takeaways

  • The DJI Mic receiver plugs into the Osmo Pocket 3's USB-C port on the bottom of the gimbal, not wirelessly.
  • The transmitter clips to your clothing or holds in your hand up to 250 meters away from the receiver.
  • The DJI Mimo app on your phone automatically detects the microphone once you power on the gimbal.
  • Transmitter and receiver pair automatically, but you can manually re-pair them by holding the pairing button on each unit for three seconds.

What you need before connecting

You will need the complete DJI Mic kit, which includes one receiver module, one or two transmitters (depending on which kit you bought), charging cases, and USB-C cables. The Osmo Pocket 3 itself comes with a USB-C cable in the box, but you can also use the cable that shipped with the DJI Mic if you prefer. Make sure your Osmo Pocket 3 battery has at least 20 percent charge — connecting the microphone does not drain the gimbal significantly, but you want enough power to test the connection.

Check that the DJI Mimo app is installed on your phone and updated to the latest version. The app is free and available on both iOS and Android. You do not need to create an account to use the microphone, but you will need the app open to monitor audio levels and switch between the transmitter and receiver if you are using multiple transmitters.

Powering on and testing the connection

After you plug the receiver into the USB-C port, power on the Osmo Pocket 3 by pressing the power button on the back of the gimbal. The receiver will light up with a blue LED, indicating it is active. Open the DJI Mimo app and tap the microphone icon in the top menu — the app should show the receiver as connected and display the battery level of both the receiver and the transmitter.

Clip the transmitter to your shirt collar or hold it in your hand, then speak into the microphone. You should see the audio level meter in the DJI Mimo app respond to your voice. If the meter does not move, check that the transmitter is powered on — press and hold the power button on the transmitter for two seconds until the LED turns on. The transmitter has a range of up to 250 meters in open space, though walls and obstacles will reduce that distance.

Adjust the microphone gain in the DJI Mimo app by tapping the microphone settings. You can set the gain to Low, Medium, or High depending on how loud your voice is and how much background noise you want to filter. Start with Medium and record a short test video to hear how it sounds before you begin filming.

Switching between transmitters

If you own the two-transmitter version of the DJI Mic, both units will pair to the same receiver automatically. In the DJI Mimo app, you can switch which transmitter the gimbal is recording from by tapping the microphone icon and selecting the transmitter you want to use. The app shows the battery level of each transmitter, so you can swap to a fresh one if the first runs low.

Both transmitters can be active at the same time, and the receiver will pick up whichever one is closer or speaking louder. If you want to use only one transmitter, you can disable the other in the app settings. This is useful if you are filming an interview and want to ensure only one person's audio is recorded.

Charging the DJI Mic components

The receiver charges through its own USB-C port on the side of the unit. The transmitters charge inside the charging case that comes in the kit — place them in the case and close the lid. The case itself charges via USB-C. Each transmitter lasts about six hours on a full charge, and the receiver lasts about eight hours. The charging case holds enough power to fully charge both transmitters three times before the case itself needs to be plugged in.

You can charge the receiver while it is plugged into the Osmo Pocket 3, though this is not necessary — the gimbal does not power the receiver. If you are filming for a long day, charge the transmitters overnight and bring the charging case with you so you can swap in a fresh transmitter if needed.

Troubleshooting connection problems

If the DJI Mimo app does not recognize the microphone after you plug it in, disconnect the receiver and reconnect it. Make sure the USB-C cable is fully inserted into the port — it should click into place. If the app still does not see the microphone, restart the Osmo Pocket 3 by holding the power button for five seconds until it shuts down, then press the power button again to turn it back on.

If the transmitter is not sending audio to the receiver, check that both devices are powered on. The transmitter LED should be solid blue when active. If the LED is off or red, press and hold the power button for two seconds. If the LED blinks red, the battery is low — place the transmitter in the charging case. If you still have no audio after charging, try re-pairing the transmitter and receiver by holding the pairing button on each unit for three seconds.

If you hear crackling or dropouts in the audio, move the transmitter closer to the receiver or remove obstacles between them. The DJI Mic uses a 2.4 GHz frequency, which can be affected by Wi-Fi routers and other wireless devices. If you are filming indoors near a router, try moving away from it or turning off the router temporarily to test the connection.

Using the microphone while recording video

Once the microphone is connected and tested, you can start recording video through the DJI Mimo app or by using the Osmo Pocket 3's built-in recording button on the gimbal itself. The microphone will record audio automatically — you do not need to do anything else. The audio from the DJI Mic transmitter will be recorded directly into your video file, replacing the gimbal's built-in microphone.

If you want to record audio from both the DJI Mic and the gimbal's built-in microphone at the same time, this is not possible — the gimbal switches to the external microphone when the receiver is connected. The DJI Mic is designed to be your primary audio source, so make sure the transmitter is positioned close enough to capture the sound you want.

Frequently Asked Questions

Can I use the DJI Mic with other cameras besides the Osmo Pocket 3?

Yes, but only with cameras that have a USB-C port and support external microphones. The DJI Mic receiver connects via USB-C, so it works with some Android phones and tablets, but not with DSLRs or mirrorless cameras that use 3.5mm audio inputs. Check your camera's manual to confirm it supports USB-C audio input before purchasing.

What happens if the receiver gets disconnected while I'm filming?

The Osmo Pocket 3 will switch back to its built-in microphone immediately. Any audio recorded before the disconnect will be saved normally. If the receiver disconnects during a shot, reconnect it and the gimbal will recognize it again within a few seconds. To avoid accidental disconnects, make sure the USB-C cable is fully seated and consider using a cable with a strain relief or securing it with tape.

How far can the transmitter be from the receiver?

The DJI Mic has a range of up to 250 meters in open space with no obstacles. Walls, buildings, and dense foliage will reduce the range significantly — typically to 50 to 100 meters indoors or in wooded areas. If you are filming outdoors in an open field, you can position the transmitter much farther from the gimbal than you could indoors.

Do I need to pair the DJI Mic every time I use it?

No. Once the transmitter and receiver are paired, they stay paired even after you power them off. You only need to re-pair them if you are adding a new transmitter, replacing a unit, or if the connection becomes unstable. For normal use, just power on both units and they will connect automatically.

Can I record audio without the DJI Mimo app open?

Yes. The microphone will record audio as long as the receiver is connected and both the receiver and transmitter are powered on. The DJI Mimo app is only needed to monitor audio levels, adjust gain, and switch between transmitters. You can close the app and the audio will still be recorded into your video file.
