Boya's BY-K5 is a tool for connecting a USB C cable to your Android smartphone while using it with (for example) a DJI Osmo Mobile. Without this adapter you won't be able to connect the cable to your smartphone, because the stabilizer is in the way. On the second picture you can see how the BY-K5 adapter solves this problem. The 90 degree bend offers the solution.
Usage BY-K5
When recording with a stabilizer or other accessory, there may be limited space to connect the USB C cable to your smartphone. With this accessory you can still make the perefect audio recordings.
