I wanted to get back to you on this.
It is possible to
carefully shave down the TFZ socket on each shell to be the same size and shape as the QDC/KZ Paragraph C socket.
I used an Xacto knife with a brand new blade (ie very sharp), and then I carefully shaved away paper thin slices (a very little at a time).
First, I shaved it down until the length of the TFZ socket matched the length of the KZ socket.
Next, I shaved it down until the width of the TFZ socket matched the width of the KZ socket).
Then the last step is to change the TFZ socket from rectangular to the curved shape of the KZ socket. To do that I shaved off the sharp corners of the rectangle at 45 degree angles.
So technically the shape I made is like this (modified TFZ socket):
Instead of like this (KZ socket):
While the corners aren’t perfectly rounded, the overall shape is close enough that it works just fine. Now I can use KZ and JC Ally Paragraph C/QDC cables on my TFZ Series 2.
Note that the
height of the KZ Paragraph C socket is taller than the TFZ socket (modded or not), so while the KZ and JC Ally cables technically fit on the modified TFZ socket, the reduced height of the TFZ socket makes the cable connection slightly less stable. To account for this, I made the TFZ socket a fairly tight fit, which can be controlled by the amount of material that’s removed from the TFZ socket. By making the length and width just a hair larger than the KZ socket, it makes the cable connection fit much tighter (and therefore more stable).
I can post photos if it would be helpful.
Do the mod at your own risk!
It is not a difficult mod, as the TFZ socket is made of soft plastic and trims very easily and cleanly. However, this mod is irreversible, and you need to decide if modding your (however much $) TFZ IEM is worth it. My Series 2 cost $10, so if I messed it up I wouldn’t have cared. Luckily, I didn’t mess it up though, but that doesn’t mean someone else with 10 thumbs and terrible eyesight wouldn’t mess it up.
Bottom line is that I take zero responsibility.
