There's a group of 'schematics'

Try one of these pin diagrams instead:

This looks right:

It's a TRRS (Tip-Ring1-Ring2-Sleeve) connector.

Serious work fir 2 channels but mono's OK ...not sure if S5 delivers mono.

Nope. It's stereo on the Tip (right channel) and Ring1 (left
channel).

When I read that, my memory started yelling RED! RIGHT! RING!.
So I checked: https://en.wikipedia.org/wiki/Phone_connector_(audio)

Yeah, something like that. Red is right and Green is left are
somewhat consistent among the headset, earphone, and microphone
connections. However, everything else, including ground, is insane.

I find myself using an ohms-guesser to check the connections just in
case someone decided to be creative.

I have found a number of (cheap, imported) cables that connect red to
tip -- the wiring is proper, just the colors are not.
