DJI Mic Mini is a wireless microphone that offers stable transmission of high-quality audio, extended battery life, and direct connection with products in the DJI OsmoAudio ecosystem. It is small, ultralight, and discreet, making it comfortable to wear and ensuring a more aesthetically pleasing on-camera appearance. The transmitter automatically enters sleep mode when it doesnt detect a signal from the receiver, conserving power and allowing for extended use.
