DJI has launched the Mic Mini 2S in China, and the main appeal is not just wireless convenience. The transmitter can keep recording locally, which helps protect audio even if the connection to a camera drops unexpectedly.
That safeguard is built around 32-bit float internal recording and 14.5 GB of built-in storage. In practice, the Mic Mini 2S can work as both a wireless microphone and a standalone voice recorder.
More protection for critical recordings
The shift to 32-bit float recording is one of the most important upgrades over the regular Mic Mini 2. Compared with 24-bit capture, the wider dynamic range gives users more room to handle sudden loud sounds and very quiet passages.
That matters in fast-moving shoots where clipping can ruin a take. It also helps preserve detail during editing, since audio levels can be adjusted more flexibly without a major quality loss.
DJI also gives users the option to store audio in RAW or processed formats. This makes the device more adaptable for creators who want either a ready-to-use file or something they can refine later in post-production.
The 14.5 GB memory inside the transmitter is enough for up to 28 hours of loop recording. Even when the wireless link to the camera is interrupted, the audio remains stored on the device as a backup.
Built for multi-speaker production
The receiver has also been expanded for more demanding setups. While the Mic Mini 2 supports two transmitters, the Mic Mini 2S can connect with up to four transmitters at once.
That makes the system more useful for podcasts, interviews, panel discussions, and other productions with multiple voices. Output can be set to mono, stereo, or quad track depending on the workflow.
The quad-track option is especially helpful in post-production because each source can be handled more cleanly. For content teams working with several speakers at the same time, that flexibility is likely to matter more than raw simplicity.

Noise reduction and broader compatibility
To improve recording quality, DJI has included two noise reduction modes. Weak mode is intended for indoor use and is designed to reduce fan noise, air conditioning, and echo.
Strong mode is aimed at outdoor environments, where it focuses on reducing wind and traffic noise. The Mic Mini 2S is also compatible with DJI’s ecosystem, including Osmo Pocket 4 and Osmo Action 6.
It also supports direct Bluetooth connection to smartphones. For users who need more freedom on set, DJI says the transmission range can reach 400 meters under ideal conditions.
Battery life and pricing in China
Battery endurance remains solid for a compact device. The transmitter is rated for up to 11 hours, while the receiver is said to last up to 10 hours on a single charge.
With the charging case, total usage rises to around 40 hours. That is slightly below the Mic Mini 2, which is rated for up to 48 hours in total, but DJI has added fast charging to reduce downtime.
The company says five minutes of charging can provide around one hour of use. In China, the Mic Mini 2S starts at 399 yuan for a single transmitter.
| China Pricing | Configuration | Price |
|---|---|---|
| Single transmitter | Transmitter only | 399 yuan |
| Phone Kit | 1 transmitter + 1 mobile receiver + case | 629 yuan |
| Standard bundle | 1 receiver + 1 transmitter | 629 yuan |
| Higher-capacity bundle | 1 receiver + 2 transmitters + charging case | 1,199 yuan |
DJI has not announced global pricing or a release timeline for the Mic Mini 2S. For now, the model remains a China-only launch aimed at creators who want a compact wireless system with stronger recording protection.
