Sony doesn't seem to wish to address the issue of replacement parts and appears to prefer charging people ~$500 USD to replace their headset with a refurbished one instead, so you're kind of on your own to fix the one you have as it is proprietary. Luckily the end that tends to break most often is just a standard USB-C 24 pin (12 pins per side). So you can, if you're skilled in the dark arts of soldering, replace the tip. It's super tiny work, and really no fun, but it's either that or fork over more money to Sony to fix an issue they shouldn't have in the first place, it's not exactly difficult to reinforce a usb connector.
The cable looks like this on the inside of the headset, so nope, not standard usb-c in there. That little white JST connector is for the "motor" controls according to Sony's teardown video.

Finding a straight-up replacement tip isn't always easy, so I tend to prefer just buying bulk usb tips that come attached to a PCB board then desolder and reconnect them where I need them.

A repaired cable should end up like this if done correctly, then you can just shrink wrap it or 3D print a new body, preferably one with more protection than the original that actually supports the cable and prevents repeat breakage.

All of this requires some skills and is not for the feint of heart as those usb-c pins are roughly 4x the width of a human hair.
