Comica Audio BoomX-D MI2 Ultracompact 2-Person Digital Wireless Microphone System for iOS Smartphones (2.4 GHz)

The Comica Audio BoomX-D MI2 Ultracompact 2-Person Digital Wireless Microphone System for iOS Smartphones only specifies the ability to adjust volume once the signal reaches the receiver (receiver output) and does not indicate the ability to adjust the input volume of the transmitters. In this scenario, a solution for input signal clipping in the transmitter could be to move the microphone further from the source of the sound, if you are able.

The volume control on the receiver enables you to raise and lower the volume of the recording going into your iOS device with lightning connector.

We have not tested the DJI OM4 with the Comica Boom-X wireless mic system on an iPhone XR to be able to say whether or not there will be any issues with balance on the OM4. The external mic will work to deliver audio, but the Mimo app does not provide control of the parameters such as turning the volume level up or down.

Yes, the receiver included with the Comica Audio BoomX-D MI2 is compatible fro use with iPhone 6S Plus.

While it is possible to connect the VideoMic to the Boom transmitter, we can not guarantee proper functionality since certain mic transmitters have specific voltage and impedance requirements from the mics which could create noise issues if not matched.

We bought the lightning (MI) version and we where only able to record the sources mixed from both transmitters in a mixed mono-track. The manual is the one for the UC version. The USB-C version and the standalone version in the bundle with 2 transmitters do have the m/s button and probably can switch mono / stereo mode. The MI bundled version with 2 transmitters does not have this button or function. However , if you look at the single MI (lighning) reciever in this shop has the m/s button. It seems that the bundled product comes with an older version of the receiver which is not able to split left and right.

Try starting the app on your iPhone using the built-in mic (without connecting the wireless system). Once the app is already running, then connect the wireless receiver to the iPhone. That may work. You will probably need to use headphones to hear the others in the Zoom meeting. Apple iOS devices may not work with an external mic when using video conferencing apps that have two-way audio, but do work for standard type video and audio recording. Comica has not provided any details about compatibility for this wireless system with Zoom meetings and Apple is constantly making changes to the software. We cannot confirm compatibility as results can vary depending on the version of the phone and operating system. However, we can confirm that the Comica BoomX-D DMI2 does work for recording audio and video with audio on the iPhone.

This should fit while using it with the DJI Mobile 3.
