Those headphone jacks can be replaced very easily - no soldering required! You just need to unscrew the controller, the jack socket is held in by friction, fix them for pennies!
Purchased a pair and had to return because the mic wasn't in the box. To be fair to the seller they replaced them very efficiently. Shame the headphone sockets on all of my XBO controllers are toast...don't seem to last five minutes (shock) .
I got these recently and the "refurb" referred to a replaced connector. They didnt do a very good job and it started to crackle after and hour or so of use. I reworked it and used glue lined headshrink, which they didnt, so there is good strain relief. My repair is solid and it now works a dream, but if you're not able to resolder the connector then I'd stay away.
