A couple of things that might explain sound differences between this cable and the Zu Mobius are the following: 1) Resistance, and 2) Polarity.
Measured the resistance shorting left and right channel at the plug, then connecting the multimeter to the left and right connector pins, so the resistance measured corresponds to twice the length of the cable. That's a longer electrical conductor, so provides a more accurate measurement.
My Zu is 10 feet long, the new cable is 11 feet long. I just used all the wire I had left; divided that total length by four and it gave that final length for this cable :-)
So the aftermarket is slightly longer than the Zu, yet its resistance is 0.2 Ohms, a third of the Zu which has 0.6 Ohms. To measure this properly, I factored out the resistance measured by the multimeter when connecting just the shorting wire. (Had to do this because this multimeter doesn't have any zero adjustment knob.)
Resistance of the shorting wire = 0.4 Ohms.

Resistance of the Zu = 1.0 - 0.4 Ohms == 0.6 Ohms:

Resistance of the new cable = 0.6 - 0.4 Ohms == 0.2 Ohms:

That might cause volume differences. Impossible for me to instant A/B compare, but it seems to me the new cable does provide a very slightly louder presentation.
Another minor difference: I switched the ground vs. signal pins. So the polarity is inverted with respect to the Zu and basically most other headphone cables. This will allow for some interesting comparisons.
Interesting result, but to be more accurate try to measure it using a bridge
Linear Mode
