phone user friendly, the 2nd cable, my best guess. NOIIICE.
The shell reminded me of the PM4, which I got in aluminum (silver'ish). I'm starting to fancy the grey a lot more!
No, the difference isn't at the 3.5mm male end (both cables have an L-shaped 3.5mm end). What's different is the 2-pin connector that connects to the IEM:
<-ZST ZS3->
And if you look at these photos, it looks like the cables won't fit cleanly around the ear when switched between models because the angle on the jacks):
<-ZST ZS3->
Specifically, the ZS3 looks like it pretty much needs a straight jack. If there was a sharp 90 degree jack on the ZS3, it wouldn't go up enough to clear the top of the ear. It appears that the straight cable from the ZS3 will fit the ZST and have more than enough room to clear the top of the ear. The only problem might be too much stress on the cable when it has to bend to go behind the ear. The of lack of a proper strain relief on the straight cable does not instill long-term confidence.
