When working with USB devices, it is necessary to purchase
relevant audio adapter cable by yourself.
For the smartphone with Android system, the Mic works well in
audio mode, it may not be compatible with most of the
smartphones in video mode (Then we suggest you to try the 3rd
party APP, such as Filmic Pro, Proshot, ect.).
For the smartphone with iOS system, the mic works well either in
audio or video mode.
