DJI has refreshed its smallest wireless mic system. The DJI Mic Mini 2S is the first in the line to record internally, with 32-bit float on the menu. Two levels of AI noise cancellation come along for the ride.
Ultra-compact
The transmitters weigh less than half an ounce (12g) and measure 1.1 by 1.1 by 0.5 inches (28.6 by 28 by 13.5mm). Clips and magnetic attachments both work for getting them close to the source. The magnetic front cover pops off, and DJI sells eight colored alternatives separately if you want to color-code talent.
Four-way connectivity
The receiver runs a bit bigger at 1.8 by 1.2 by 0.8 inches (46.50 by 29.61 by 19.32mm). Still, at 0.7 ounces (19g), it adds nothing meaningful to a camera rig. One receiver pairs with up to four transmitters. It also talks to Mic Mini and Mini 2 transmitters, so an existing kit isn’t stranded. A TRS cable handles the camera connection. Sony shooters can pull four-channel audio through the optional DJI Mic Series Camera Adapter.
Internal recording
Each transmitter records to 14.5GB of onboard storage in either 24-bit or 32-bit float. That’s up to 28 hours of 24-bit audio. The 32-bit float mode captures enough dynamic range that clipping stops being something you think about on set.
AI noise cancelling
DJI says the Mic Mini 2S runs a new proprietary noise-canceling model with two strength settings. Basic targets indoor offenders: HVAC hum, fan noise, room reverb. Strong goes after harsher outdoor noise to keep a voice intelligible. Three tone presets round it out, labeled Regular, Rich and Bright.
Battery life
A transmitter runs up to 11 hours per charge and refills in roughly 70 minutes. The receiver manages 10 hours but takes 2 hours to top off. Total runtime stretches to 40 hours with the charging case, which holds two transmitters plus a receiver. There’s room in there for a mobile receiver and the TRS cable too.
Other features
Two adaptive gain modes handle level management. Clipping Control catches sudden spikes. Loudness Balance keeps things steady across an interview or a long stream. Several DJI cameras take the transmitters directly with no receiver in the chain, including the Osmo Pocket 4, Osmo 360, Osmo Nano and Osmo Action 6. An optional mobile receiver covers smartphone connections.
What we think
Internal recording is the headline here, and it earns the spot. Wireless mics drop out. Interference happens, talent walks behind a wall, someone’s phone sits too close to the transmitter. A backup track recorded at the source turns a ruined interview into a minor sync task in post.
The backward compatibility deserves attention too. Pairing older Mic Mini and Mini 2 transmitters to a 2S receiver means expanding to four channels without buying four new transmitters. That’s a rare bit of generosity in an ecosystem that usually rewards starting over.
Yes, it costs more than the Mic Mini 2. The internal recording alone covers the difference.
Pricing and availability
The Mic Mini 2S is on sale worldwide, though not in the U.S. In the UK, a single transmitter runs £59 ($79). A kit with two transmitters, a receiver and a charging case goes for £169 ($227).
