My multimeter only measures with a precision of 0.1Ohm, so this is as good as it gets. A rough reference, I guess.

Both A and B connectors, both sides L&R measure 0.7Ohms. The angled one I have with a mic, it has a different 3.5mm connector with more separations. The mic side on one of the separations measures 1Ohm.

2-pin,
L&R measure 0.1Ohm. Though when I bought it the price was 15€. Great deal, if the wire they send hasn't changed.

MMCX, L&R measure 0.3Ohms.
The last one on the list is much softer than the second one, but also tangles a bit easier. I don't hear much of a difference with any of them.
