DJI Mic Mini 2S review: The best tiny mic now offers a pro experience

With internal 32-bit float recording, it’s got nearly everything a creator needs.

Since it first launched, DJI's wireless Mic Mini series has been a hit with vloggers and creators. It's easy to see why: They're inexpensive, reliable, easy to use and offer high-quality voice recording. That's a big upgrade from old-school wireless systems that were often expensive, tricky to set up and prone to interference. There has been one key feature lacking, though. Some pros have avoided DJI's Mic Mini models because they can't record audio internally, leaving no backup if something goes wrong.

DJI just rectified that issue with the Mic Mini 2S . It can record to internal memory at 32-bit float quality, giving content pros not only a high-quality backup but protection against clipped audio. The new model also lets you capture audio from four mics at once like the Mic 3 . Those upgrades could convince many who are still sitting on the fence to finally use a set of DJI Mini microphones. But as I discovered with my testing, those might not be enough to win over all pros for other reasons I'll get into.

The Mic Mini 2S transmitters (mics) largely resemble the Mic Mini 2 and weigh just a gram more at 12 grams. That tiny bit of extra weight is due to the 14.5GB of internal memory now lurking inside each transmitter. It's enough to capture 28 hours of 24-bit audio, or about 22 hours of 32-bit float audio. More on that shortly.

There are also a few subtle physical changes. The clear cover is slightly more transparent than before and has a tiny "Mini 2S" logo in orange and gray. The power button is also orange instead of clear, and the embossed logo now sticks out by about a millimeter. Why? Well, the 10 colorful mic covers included with the camera kit now have a cutout that fits neatly over that protruding logo.

Speaking of which, I know that DJI wants to promote its products, but many pros really do not want its logo to appear in their videos. The company really needs to provide a cover or some other way of blocking it out. They can even charge extra for one! People will pay!

As before, the Mic Mini 2S comes in smartphone and camera kits. The latter includes a receiver with a 3.5mm mic output and cable for mirrorless cameras, along with two mics, a charging case and other accessories. The former offers a mobile receiver with a smartphone USB-C port, along with a single transmitter and charging case.

The camera receiver has a volume knob, 3.5mm mic port, power and Bluetooth buttons and a clip that slides onto your camera's hot shoe. It supports up to four transmitters at once, two more than the Mic Mini 2, with four numbered LEDs showing which are connected. As for the smartphone receiver, it includes a male USB-C connection for the phone and a female pass-through for charging, plus a switch for noise reduction.
