For antenna purposes and those frequencies, are there any differences
from one headset to another?

Somewhat. There are headsets (4 wires) and earphones (3 wires).
Either will work. The problem is that some of the headsets come with
shielded wires, which will cause reception problems. I've only seen
one like this, and it has an easily identified thick cable.

Wrong! The shield is used as the antenna!

If that's true, then why does my shielded cable earphones fail to hear
much on FM?

Notice that he's connecting the antenna wire to the center pin, not
the ground.

I can't tell what this one is doing:

If I have time, I'll play with a connector and see which pin is the
antenna.
