The mini review of the tiny wireless microphones was done by the DJI
The DJI Mic Mini: A Wireless Adapter and Charger for the Osmo Action 5, Pro, Omega, Pocket 3 and Upsilon
Put the charging case side by side with the DJI Mic 2 and you may not be all that impressed at the “mini-fication” happening here. The case is not as long, but they’re otherwise similar. You’ll probably say, “Oh wow” when you put the mics next to each other. Is just me the only one? The Mic Mini is 10 grams (!) whereas the Mic 2 is 28 grams.
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 has a dial that can be used to adjust the level of sound coming in, as well as a 3.5mm audio cable.
The Mic Mini allows you to purchase parts without paying the full price of the system. If you do, you get a receiver that plugs into your camera, two transmitters that go onto your body and a charging case that stores all three of them. A carrying pouch and 3.5-mm audio cable are included with the package.
You can either buy one receiver and one transmitter, or both. If you decide to add a second, you will need to pay $59 for the transmitters. And if something ever happens to the charging case, that’s $49. You get options and don’t have to pay one flat price for an extra mic you won’t need.
