[DigitalToday reporter Jinju Hong (홍진주)] DJI unveiled a new compact wireless microphone as it steps up its push into the creator audio equipment market. It added onboard recording and multi-transmitter support, functions that were seen as lacking in the previous model. The additions improve usability across shooting environments ranging from solo content to interviews and podcasts.

Tech site TechRadar reported on Monday local time that DJI unveiled the ultra-compact wireless microphone 'Mic Mini 2S'. It is a follow-up model introduced just days after the launch of the 'Mic Mini 2'. It keeps the product size and entry-level positioning while strengthening features demanded in real-world shoots.

The biggest change is the addition of recording on the transmitter itself. The Mic Mini 2S has 16GB of built-in storage, allowing it to store audio directly without connecting to a receiver or camera.

DJI said maximum storage time is about 28 hours based on 24-bit recording and up to about 22 hours for 32-bit float recording. It said 32-bit float recording is a feature preferred by video producers because it can reduce loss of sound quality during sudden volume changes.

The number of transmitters that can be connected at the same time has also increased. The Mic Mini 2 supported only two transmitters, but the new model can use up to four transmitters simultaneously.

That allows use in production settings involving multiple participants, such as podcasts, small panel interviews and multi-person shoots, without adding separate equipment. Recording modes also expand, adding quadraphonic mode to existing mono, stereo and safety track options.

Noise reduction has also been improved. DJI said it applied NPU-based AI noise reduction technology instead of the existing active noise cancellation method. Users can choose between two noise reduction modes, basic and strong, and DJI said it improved vocal clarity and reduced distortion compared with the previous model.

File transfer is also faster. Recorded files stored in the charging case can be pulled directly from the transmitter at speeds of up to 34 MB/s. DJI stressed that this is about twice as fast as its higher-end 'Mic 3'. It said a 30-minute 24-bit recording file can be transferred in about 8 seconds.

The charging case design has also changed. The new case is designed to hold two transmitters, one receiver, a mobile receiver and a 3.5 mm audio cable. That means users can manage all components that were difficult to carry together in the previous product.

Battery performance has declined slightly. The Mic Mini 2S transmitter runs for up to 11 hours and the receiver for up to 10 hours, down from 11.5 hours and 10.5 hours in the earlier model. Total runtime including the charging case also fell to 40 hours from 48 hours. Battery efficiency appears to have dropped somewhat due to onboard recording and additional hardware.

Existing DJI ecosystem integration features remain. It supports three voice tone presets, up to a 400 m transmission range and direct connection with Osmo products.

Compatibility with newly released products has also expanded. The Mic Mini 2S works with the 'Osmo Pocket 4P', as well as the 'Osmo Pocket 4', 'Osmo 360', 'Osmo Nano' and 'Osmo Action 6'.

Pricing varies by configuration. A single transmitter-receiver set sells from 79 pounds, while a mobile receiver kit starts at 149 Australian dollars. A full package including two transmitters, one receiver and a charging case starts at 169 pounds, or 279 Australian dollars. A transmitter alone starts at 59 pounds, and a charging case starts at 29 pounds.

A U.S. launch has not been confirmed. DJI said it has no plans to release the product in the U.S. market for the time being because regulatory approvals remain.

Industry watchers are assessing the Mic Mini 2S as a product that expands the range of uses for compact wireless microphones rather than a simple generational update. Analysts say DJI's strategy has become clearer, targeting not only solo creators but also interviews, podcasts and small production teams by adding onboard recording and support for up to four transmitters.
