不兼容麦克风配件不是一个全部通用的类别
Insta360 Mic Adapter 的 Vertical Version 支持 X2，X3、X4 和 X5 / X4 Air Mic Adapter 均不支持。因此只写“Insta360 麦克风转接头”的商品名称不足以确认适配。
面向 RØDE Wireless GO 的 X Series Upgraded Invisible Mic Cold Shoe 另行列为支持。冷靴与信号转接头是不同条目，支持其中一个不能作为另一个的证明。
保留明确共享项目，不猜其他配件
X2 支持自己的 X2 Fast Charge Hub 与 X2 Lens Cap，不支持对应 X3 项目。X Series USB-C Cable 与 Bullet Time Cord 则是表中明确共享的配件。
整理已有套装时按这些具名条目逐件核对。没有列出的项目在这里属于未确认，配件新旧或品牌相同都不能补上缺失的配对依据。
