Not compatibleMicrophone accessories are not a single interchangeable category
The Vertical Version of the Insta360 Mic Adapter is supported for X2. The X3 Mic Adapter, X4 Mic Adapter and X5 / X4 Air Mic Adapter are not supported. A listing shortened to “Insta360 mic adapter” is therefore insufficient to settle fit.
The X Series Upgraded Invisible Mic Cold Shoe for RØDE Wireless GO is separately listed as supported. A cold-shoe pairing and a signal-adapter pairing are different entries; support for one should not be used as proof for the other.
Preserve the useful shared items without guessing the rest
X2 supports its X2 Fast Charge Hub and X2 Lens Cap, while the X3 counterparts are not supported. The X Series USB-C Cable and Bullet Time Cord are explicit shared items in the table.
Use these named entries to sort what you already own. If an item is not listed, the answer here is unconfirmed; neither its age nor a common brand name establishes the missing pairing.
