DJI launches the Mic Mini 2S with 32-bit internal recording, 14.5GB built-in storage

As earlier reported, DJI has officially launched the Mic Mini 2S in China. Arriving just months after the standard Mic Mini 2, the 2S shifts focus from everyday vloggers to professionals who require complex audio routing and onboard failsafes.

The biggest upgrade over the Mic Mini 2 is the addition of 14.5GB of internal memory within the transmitter, enabling up to 28 hours of direct loop recording. More importantly, this storage supports 32-bit floating-point internal recording. Unlike the standard 24-bit audio found on the Mic Mini 2, 32-bit float captures a massive dynamic range that effectively prevents audio clipping during sudden loud noises while retaining clarity in quiet environments, giving solo shooters a reliable backup file if wireless transmission fails.

To accommodate the internal memory and processing, the new transmitter weighs 12g, which is a marginal 1g increase over the Mic Mini 2. The receiver has also seen a substantial bandwidth upgrade. The standard Mic Mini 2 is limited to standard dual-channel recording, but the 2S receiver can be paired with up to four transmitters at the same time.

This enables quad-track output, which is a huge time saver in post-production when editing roundtable discussions, multi-subject interviews, or complex ambient setups. The Mini 2S also maintains native ecosystem integration with existing DJI hardware, such as the Osmo Pocket 4 and Action 6, and continues to offer direct Bluetooth pairing to smartphones with up to 400 meters of line-of-sight transmission range.

The inclusion of internal processing introduces a slight compromise in power efficiency. The Mic Mini 2S transmitter provides up to 11 hours of native runtime, and the receiver offers 10 hours. When paired with the charging case, the total usage time is rated at 40 hours. This is a noticeable decrease from the 48-hour total usage time of the standard Mic Mini 2.

To handle environmental audio, the system integrates a two-stage active noise reduction system featuring a weak mode tuned for indoor reflections and HVAC hums, alongside a strong mode optimized for aggressively filtering traffic and wind noise outdoors.

Currently, the Mic Mini 2S is only available in China, with the company offering a couple of bundles. The full kit, including the charging case, is 1,199 CNY (about $165). The standard one-to-one package costs 629 CNY (about $93), but if you just need a transmitter, then they are sold separately for 399 CNY (about $59).

The Mic Mini 2S should be coming to the rest of the world soon, but DJI has not yet announced official pricing for regions outside of China.
