If it can help, here is the link of the MMCX PINs I always buy from ali (good seller and nice package, I recommend).
A bit expensive but didn't found cheaper for now for 10 pairs (at this exact dimensions). Excellent quality, and all my units are working perfectly for now

Thanks. I might try to get 2 pair. One for earbud and one to fix my xe800 iem.

Edit * maybe 3 pair, my piston also in dire need of repair (if I can find a way to open it.)

Edit 2

Those 150 ohm, is there any reference (to common earbud) in how they sound? Seems interesting

Just bought some drivers. So I got a couple of drivers. I am confused which lead is + and which lead is - on both of these can someone give me a pointer?

With the driver connections nearest you, + is on the left

@spikyfugu
In each driver, you need to find a mark that identifies the side with the same polarity solder connector.

For example, in each of the 600ohm drivers (see photos), there is a RED dot that identifies the same polarity solder point side.
In the 150ohm drivers (see photos), the same polarity side is marked with a BLACK line (and some color painted in that side metal).

@Merlin-PT

So for 600ohm one, the red dot side means the polarity (+) side and the opposite side is ground (-)?
And for 150ohm one, the black line side is polarity (+) and the opposite side is ground (-)?

 

[Merlin-PT]

Yes, I use the color mark in the drivers as the positive and no mark as ground.

Thanks for the pointer
