The DJI Mic Mini Wireless Receiver, Transmitters, and Audio Adapter for the Osmo Action 5, Pro, and Pocket 3

Although the DJI Mic Mini seems like an improvement over the DJI Mic 2 system in many ways, it’s not a replacement. The Mic Mini transmitters lack the ability to record backup audio on their own. If that is a concern, you will need to use the Mimo app from DJI to take a second safety track at a lower volume to avoid clipping and distortion.

The mic transmitters can connect directly to smartphones and mobile devices over Bluetooth or to DJI devices, including the Osmo Action 5 Pro, Osmo Action 4, and Osmo Pocket 3. Two of them can also be simultaneously connected to the Mic Mini wireless receiver to boost transmission ranges to up to 400 meters. The receiver connects to other devices over USB-C, Lightning, or a 3.5mm audio cable and features a dial with five gain settings to adjust the level of incoming sound.

What’s cool about the Mic Mini is that you can buy the parts you want without paying the full $169 for the full system. You’ll get a receiver, two transmitters, and a charging case if you do, but you’ll have to use the built-in battery. The package also includes a carrying pouch, and a 3.5-mm audio cable to connect to a camera.

You can pay $89 for one receiver and one transmitter. The transmitters go for $59 each if you decide to add a second later. If something bad happens to the case, that’s $49. You don’t have to pay a single price for a mic that you won’t need.
