Jaybird X3 Charger Clip
thingiverse
Here's a charging clip for the Jaybird X3 that might also work on the X4. I've included images of the pogo pins and the micro USB connector board I used in this project. So far, I haven't tested it out, but it should work just fine. If there are any updates or changes, I'll be sure to update the file accordingly. Please make certain that you get the pins right, otherwise, you risk damaging your earphones.
