DJI Mic Mini 2S (2 TX + 1 RX + Charging Case)
DJI Mic Mini 2S (2 TX + 1 RX + Charging Case)
The DJI Mic Mini lavalier microphone operates on a condenser principle and uses an omnidirectional polar pattern to capture sound from all around. Wireless transmission is handled by digital technology and a Bluetooth interface, complemented by a USB-C connector on the receiver. The transmitter includes a 3.5mm jack for connecting external devices. This compact system records sound with high precision in various conditions. It is compatible with Windows and Android operating systems.

Sound Pickup and Polar Pattern
The condenser system captures sound with high sensitivity (-30dB) across the entire frequency range from 20Hz to 20,000Hz. The omnidirectional pattern picks up the surrounding environment evenly from all directions, eliminating the need to aim it precisely at the speaker's mouth. This recording method preserves the natural tone of the human voice even when moving around the space. The device works with two channels for stereophonic or monophonic recording.
Ambient Noise Cancellation and Wind Protection
An advanced algorithm with artificial intelligence cleans the audio track of unwanted noise. Users can choose between two levels of noise cancellation, with the stronger mode targeting challenging outdoor conditions. The intelligent filtering effectively isolates human speech from background noise. Three sound profiles are also available for optimal frequency balancing.
Connectivity and Outputs
The receiver offers a USB-C connector for direct connection to compatible devices running Windows and Android. The transmitter includes a 3.5mm jack for connecting other external microphones. The digital interface provides stable, high-quality signal transmission. Bluetooth wireless technology expands connectivity options with mobile phones.
Wireless Transmission and Range
Wireless transmission uses reliable digital technology with a range of up to 400m with a direct line of sight. When connected to a mobile receiver, the range is around 300m. The wireless connection works reliably over long distances without signal interference. In addition, the system supports a direct OsmoAudio connection with selected cameras without the need for an external receiver.
Power, Battery and Charging
The entire system is powered by a battery with a total life of up to 40 hours. The transmitter itself can operate for up to 11 hours, and the receiver works for 10 hours without interruption. Fast charging provides enough power for another hour of operation in just five minutes. An automatic power-off function after 15 minutes of inactivity helps to save energy.
Internal Storage and Recording Formats
Recording is done in a dynamic 32-bit format with a wide range, which eliminates the need for continuous sensitivity adjustment. The 14.5GB internal storage can hold up to 28 hours of backup recording. Backup recording protects the audio track from unwanted clipping or signal loss during a sudden shout or quiet whisper. The converter operates at a sampling rate of 48kHz and a bit depth of 24 bits.
Controls and Display
The DJI Mimo app is used for advanced settings and activating the safety track with -6dB attenuation. The system offers two intelligent volume adjustment modes for balanced speech. The Clipping Control function prevents unwanted distortion of the sound during sudden changes in volume. Loudness Balance then maintains a constant signal level during a smooth conversation.
Attachment and Design
The miniature transmitter weighs just 12g and can be attached to your clothes with a magnet or rotating clip. The total dimensions of the case are 42.5 × 59.2 × 106.3mm with a total weight of 290g. The compact design makes it easy to transport daily and wear discreetly under clothing.

Microphone Principle
A dynamic microphone is suitable for open performances, live broadcasts, music production, etc. It uses a magnet and a moving coil to capture sound.
A condenser microphone is especially useful for studio purposes. It has higher sensitivity and lower noise. It must be powered separately.
Frequency Range
The frequency range indicates the range of frequency values that the microphone records. The wider the range, the more sounds it can capture.
Low frequencies (e.g., 20–200Hz): Bass, the deepest tones of instruments (double bass, kick drum) and male voices.
Mid-frequencies (e.g., 200–3,000Hz): The body of instruments, the foundation of the voice where the ear is most sensitive, important for speech intelligibility.
High frequencies (e.g., 3,000–14,000Hz): Treble, details, sibilance and the "sheen" of the sound.
Air band (above 14,000Hz): Gives recordings a sense of expensive, super-high-quality sound and space.
Sensitivity
Microphone sensitivity is the ratio of the output voltage to the acoustic pressure. It expresses how loud a signal the microphone produces at a given acoustic pressure; higher sensitivity means a stronger voltage and is suitable for quiet studios, while lower sensitivity is better for noisy environments as it amplifies less unnecessary ambient noise.
