DJI has officially announced its latest wireless microphone system, the Mic Mini, which promises to deliver improved portability and battery life while making some significant compromises in the process. The new system, which is now available for purchase, weighs in at less than half the size of its predecessor, the DJI Mic 2, but sacrifices built-in recording and the ability to connect external lav mics.

One of the most notable omissions from the Mic Mini system is the lack of built-in backup recording, a feature that was present in the DJI Mic 2. This means that users will need to rely on their recording software, such as DJI's Mimo app, to capture a secondary safety track in case of audio clipping or distortion. Additionally, the Mic Mini transmitters do not have a 3.5mm input, which prevents users from connecting their own lav mics and instead forces them to use the included microphones.

Despite these trade-offs, the Mic Mini system does offer some significant improvements over its predecessor. The transmitters, which weigh in at just 10 grams, are physically smaller and more discreet than before, making them ideal for clipping to clothing or wearing with magnets or a lanyard. The battery life has also seen a significant boost, with the mic transmitter capable of running for up to 11.5 hours on a single charge, and the wireless receiver lasting up to 10.5 hours. When paired with the charging case, the system can be used for up to 48 hours without needing to be recharged.

In terms of connectivity, the Mic Mini system is compatible with a range of devices, including smartphones, DJI's Osmo Action 5 Pro, Osmo Action 4, and Osmo Pocket 3. The receiver can connect to devices over USB-C, Lightning, or a 3.5mm audio cable, and features a dial with five gain settings to adjust the level of incoming sound. Up to two mic transmitters can be simultaneously connected to the wireless receiver, boosting transmission ranges to up to 400 meters.

The Mic Mini system is available in two bundles: a $169 kit that includes two microphone transmitters, a wireless receiver, a charging case, and other accessories, and a cheaper $89 bundle that skips the charging case and only includes a single mic transmitter and the wireless receiver. The mic transmitters can also be purchased individually for $59 each, while the charging case is available for $49.

While the Mic Mini system may not be a direct replacement for the DJI Mic 2, it does offer a compelling solution for users who prioritize portability and battery life. However, for professionals who require more advanced features, such as built-in recording and lav mic compatibility, the Mic Mini may not be the best option.

Ultimately, the Mic Mini system represents a significant shift in DJI's approach to wireless microphone design, one that prioritizes convenience and ease of use over raw feature power. As the market for wireless microphones continues to evolve, it will be interesting to see how DJI's competitors respond to this new approach.
