The "Mic Adapter (X4)" microphone adapter is designed specifically for the Insta360 X4 camera and is not compatible with the Insta360 X3. The microphone adapters for the X2 and X3 models do not work with the X4, and vice versa.
However, it is possible to use the microphone adapter from the X3 on the X4, but it doesn't fit perfectly because of the size differences between the two cameras, which can affect the aesthetics and attachment. For optimum compatibility, we recommend using the microphone adapter dedicated to each model.
The RØDE Lavalier GO, plus the RØDE windscreen Minifur-LAV or the affordable Delock tie lav. The RØDE smartLav+ does not work with the Insta360 X4, nor does the RØDE 3.5mm jack - 3.5mm socket. All tested by myself.
The price is determined by various influences, such as the purchasing conditions specified by the supplier. We always endeavour to offer a price in line with the market.
