Continuity on 1/8” male headphone plug

[qb748]

Super basic questions.

Im messing with testing continuity on various pairs of headphones, in attempt to verify my understanding of basic concepts and connections.

I have a working set of stereo headphones. No mic, just left and right (TRS).

Obviously, I get continuity when i touch probes to tip and sleeve, and then between ring and sleeve. For fun, I probed tip and ring and i get a connection. The resistance is about double that of the previous.

What is going on here?.. how is there a path of conduction?

There are two earpieces, both connected from one side to the ground (sleeve) of the plug.

The other sides of the earpieces go to tip and ring on the plug.

So sleeve to tip or ring reads through one or the other earpiece, while tip to ring reads through both in series.
