DJI Mic Mini 2S Review: Tiny Mics Get a Colossal Upgrade

It wasn’t that long ago that capturing good wireless audio meant spending hundreds of dollars on bulky, portable equipment. For creators filming primarily on an iPhone or Android, the microphone setup could sometimes feel more cumbersome than the camera itself. DJI has spent the past few years systematically removing those barriers, and the new DJI Mic Mini 2S may be its most compelling attempt yet.

At first glance, the DJI Mic Mini 2S looks remarkably similar to the Mic Mini 2, which was released in April. The transmitters remain tiny, magnetic and light enough that you can clip one onto a shirt without tugging or dragging it down from its weight. However, the most important upgrades are hidden inside.

DJI has finally added internal recording to its Mini lineup alongside 32-bit float support, while the receiver can now work with up to four transmitters. Those additions push the Mic Mini 2S beyond being a convenient microphone for TikTok videos and into territory where I’d feel far more comfortable using it for interviews, event coverage and professional shoots. As a $265 piece of recording equipment, the DJI Mic Mini 2S quickly became a part of my content creation arsenal.

Out of the Box

While striving to improve on itself, DJI hasn’t tampered with what works on the Mic Mini 2. Each Mic Mini 2S transmitter measures just 28.58 x 28.04 x 13.52mm and weighs approximately 12g without the magnetic clip. The receiver is similarly compact at 46.50 x 29.61 x 19.32mm and weighs only 19g.

That makes a noticeable difference when recording yourself. For a quick video, I could magnetically attach a transmitter to my shirt, connect the receiver to either my iPhone 17 Pro or my Sony ZV-E10 camera and essentially forget about the microphone. There’s no cumbersome wire running beneath a shirt, and the transmitter doesn’t pull heavily on lighter clothing. Within moments, I had a subtle yet very effective recording setup prepared.

The magnetic system also makes repositioning the microphone incredibly easy. Moving from a T-shirt to a jacket, for instance, takes seconds. The Mic Mini 2S still offers a clip that can be used with thicker clothing where the magnet might be easier to knock loose, but the flexibility is welcome.

One of my favourite features is the swappable face covers for the Mic Mini 2S. DJI embraces the fact that wireless microphones are visible on camera in so many videos. So, the company is offering the ability to customize the Mic Mini 2S’s front cover with eight colour choices. These magnetic front covers can change the appearance of the transmitters. These are great for creators who want something other than a black square hanging from their shirt.

That being said, there’s still no 3.5mm lavalier input, though. If you’re filming something where the microphone needs to disappear entirely, the Mic Mini 2S isn’t necessarily the right DJI system. For YouTube, Instagram, TikTok and general mobile production, I suspect most people won’t care.

Internal recording changes everything

The selling feature and what would make me choose the Mic Mini 2S over the cheaper Mic Mini 2 is internal recording. Each transmitter includes 16GB of storage, providing enough room for roughly 28 hours of 24-bit audio. DJI also supports 32-bit float recording, which provides significantly more latitude when recovering audio that suddenly becomes too loud or quiet.

This might sound like a feature aimed exclusively at professional creators, but it solves an incredibly basic problem: wireless connections can fail. Imagine recording an interview at a busy launch event. Everything appears normal on your iPhone, but interference causes the wireless signal to briefly drop. Without internal recording, that portion of the conversation could simply be gone.

With the Mic Mini 2S, the transmitter itself is recording a backup. That alone dramatically changes how comfortable I am using such a small wireless system for important shoots. I’ve gone through the pain and sorrow of losing out on interviews conducted thanks to failing tech. Having internal recording is a safety net to not lose precious recordings. Internal storage has long been one of the features separating DJI’s cheaper microphones from its higher-end products. Bringing it into the Mini lineup makes the 2S significantly easier to recommend.

There is one strange limitation. Internal recordings currently need to be retrieved through DJI’s full-sized charging case. If you buy a smaller mobile bundle, accessing those recordings isn’t nearly as convenient. Hopefully, DJI eventually enables wireless transfers through the DJI Mimo app.

Audio punches well above its size

The Mic Mini 2S records at up to 48kHz with support for both 24-bit and 32-bit float audio. Voices come through cleanly with substantially more depth and presence than what you’d typically capture using an iPhone from several feet away. That difference becomes especially noticeable when filming somewhere busy.

Recording directly through a phone means its microphone is capturing everything between you and the device: room reflections, nearby conversations, traffic and wind. Putting the Mic Mini 2S several inches from your mouth immediately isolates your voice far more effectively.

DJI also offers three voice presets through the Mimo app: Regular, Rich and Bright. Regular provides the most neutral presentation, while Rich emphasizes lower frequencies and Bright pushes clarity further.

For most of my recording, I’d stick with Regular. It provides a cleaner foundation if you plan on adjusting EQ while editing. Rich can sound pleasant for voices lacking lower-end presence, while Bright makes more sense when recording somewhere where dialogue needs to cut through environmental noise. Creators who want to shoot, edit and post entirely from an iPhone may appreciate having those options available without opening an audio editor.

DJI has also upgraded noise cancellation with AI processing. Basic and Strong modes are available, and the difference is immediately noticeable when recording outdoors or around persistent background sounds.  In Regular mode, traffic, HVAC systems and people walking behind you remain clearly audible. Basic noise cancellation lowers much of that background while preserving enough ambience that the recording still sounds natural.

Strong mode is far more aggressive. It can dramatically suppress consistent background noise, but your voice can begin sounding processed in particularly challenging environments. Testing cited in the supplied material similarly found the strongest mode capable of eliminating substantial environmental noise while introducing only slight processing around the voice.

I’d leave it on Basic for most circumstances and reserve Strong for situations where getting intelligible dialogue matters more than maintaining completely natural sound.

Four microphones from one tiny receiver

The other major Mic Mini 2S upgrade becomes useful as productions get larger. One receiver can connect to as many as four transmitters, double the two-transmitter limit of the Mic Mini 2. The system can output four individual tracks using Quadraphonic mode when connected to compatible camera or computer setups.

For someone primarily filming solo videos on an iPhone, that’s probably overkill. However, it creates room to grow. A two-person interview can eventually become a three-person podcast without requiring an entirely new wireless system. For event coverage, you could mic several people simultaneously and retain individual tracks for editing afterwards.

DJI also supports compatibility across several of its microphone generations, making the Mic Mini 2S surprisingly expandable for something positioned below its flagship systems. Wireless range reaches up to 400 metres under ideal open, unobstructed conditions. In reality, very few creators are going to place themselves nearly four football fields away from their camera, but the generous range translates into a stable connection at the much shorter distances most people will actually use.

Battery life easily handles a shooting day

The Mic Mini 2S transmitter can run for roughly 11 hours, while the receiver lasts around 10 hours. The charging case extends the system well beyond a single recording session. In practical terms, battery anxiety was never really part of the experience.

For an afternoon spent recording several short-form videos, interviews and B-roll, the system has more than enough endurance. Dropping everything back into the charging case between shoots makes battery management almost invisible. That matters because the best creator accessories are often the ones you don’t need to think about.

Final thoughts

The DJI Mic Mini 2S occupies an interesting middle ground. The Mic Mini 2 remains the more sensible option if all you need is inexpensive wireless audio for casual videos. The Mic Mini 2S costs considerably more, with the mobile-focused package starting around $149 CAD and the more complete two-transmitter and receiver kit priced around $265 CAD, but it justifies its price with substantial creator-friendly upgrades.

Internal recording means a wireless dropout no longer has to ruin an interview. 32-bit float provides significantly more flexibility when recording unpredictable voices. Four-transmitter support means the same system can scale alongside increasingly ambitious productions. The original Mic Mini proved wireless microphones didn’t need to be bulky or expensive. The Mic Mini 2S takes that idea and removes one of the compromises that prevented the smaller system from being something I’d completely trust for important shoots.

For someone recording the occasional Instagram Reel, it’s probably more microphone than necessary. For creators regularly filming interviews, product videos, events or professional content from an iPhone, however, the Mic Mini 2S hits a particularly compelling balance between portability and capability. It’s small enough to forget you’re wearing it, but finally robust enough that you don’t have to worry about whether it captured the take.
