"You can also take the KZ 8-braid silver upgrade cable, and trim the plastic off of the plug like many of us do. After doing that, the pins are even longer than the TRN (and have no problems fitting anything)! A little later, I'll post a comparison photo of all 3 side by side to show the differences."
Here is that photo as promised.
You can see the different pin lengths of the following:
1 Unmodified KZ cable (stock and KZ upgrade cables)
2. Modified KZ 8-wire braided upgrade cable (with plastic shoulder cut off)
3. TRN cable (black and silver)
Ignore the shoulder type (ie ZST vs ZS3); just look at the length of the actual pins.
You can use the longer pin lengths to fit IEMs that fit too loosely (with the stock cables) and on IEMs they were not designed for (like one that was intended for the thinner ZS3 shoulder). And no, it does not hurt the IEM in any way to use the longer pins. The KZ 2-pin female socket is incredibly deep, and can accommodate the long pins with ease.
In other words, the modified cable (#2) is the most "universal". The only downside is that once you trim off the plastic shoulder, you cannot tell the proper direction of the pins to ensure you are plugging them in properly (ie not out-of-phase). Therefore, what I do
BEFORE trimming off the plastic, is mark the cables by scratching a mark on the aluminum shoulder where the "rounded" end would normally go using a sharp tool (like a sewing needle). If you have no idea what I'm referring to, check this link:
