Will it even be necessary? If the CIEM is tuned with the stock cable and sounds amazing (we hope) out of the stock cable why would we need to change it?
I really like how the cable is reinforced and screwed down where it meets the body of the CIEM. That means the pins shouldn't bend and that spot will no longer be a point of weakness.
I had a very difficult time beating the stock cable on the JH13fp. Things would be better at something but not overall so. Stock should be fine and may be something better that his others as well.
