10 g Transmitters and Magnetic Mounting
Each transmitter weighs 10 g, which is the Mic Mini's defining feature. At that weight it clips to a T-shirt or a light blouse without dragging the fabric down, and it is small enough to be easy to overlook on camera. Two clip magnets come in the box, so a transmitter can sit on the outside of a garment held by a magnet underneath, which makes positioning quick and avoids clip marks on delicate fabric. The strong magnets are handy, but DJI warns they should be kept away from pacemakers and other implanted medical devices, as well as cards and hard drives. The pickup pattern is omnidirectional, which forgives a speaker turning their head, and two windscreens are included for outdoor use, where they soften wind noise and plosive pops. The main downside of something this small is that it is easy to misplace. One owner makes a habit of returning each transmitter to its dock straight after filming, which is sensible advice. The transmitters are not waterproof either, so heavy rain or a sweaty outdoor shoot calls for some care.
