The Voice Tone Preset modes can be selected via the DJI Mimo app, with the default set to Regular. This function is not supported when the transmitter is directly connected to a phone via Bluetooth.

Strong and Basic noise cancellation levels can be set via the DJI Mimo app, or directly on the product interface when using an Osmo Pocket 3, Osmo 360, Osmo Nano, or Osmo Action 6 connected to the transmitter via DJI OsmoAudio Direct Connection. When the transmitter directly connects to the phone, the noise cancellation level cannot be adjusted in the DJI Mimo app; it defaults to the Strong level. The noise cancellation switch on the DJI Mic Series Mobile Receiver allows quick adjustment of noise cancellation levels (Off = O, Low = L, High = H).

When the DJI Mic Mini 2 Transmitter is connected to the DJI Mic Mini Receiver/DJI Mic Series Mobile Receiver, this feature is enabled by default and can be turned on/off via the DJI Mimo app. When the transmitter is directly connected to a phone via Bluetooth, this feature is enabled by default and cannot be turned off. When an Osmo Pocket 3, Osmo 360, Osmo Nano, or Osmo Action 6 is connected directly via OsmoAudio, settings can be adjusted on the product interface.

The DJI Mic Mini 2 Transmitters can directly connect to select DJI products (up to two TX for Osmo Pocket 3, Osmo 360, Osmo Nano, and Osmo Action 6). The transmitter's operating time is approx. 7 to 8 hours when directly connected. Additional DJI products will be supported in the future.
