No they dont; the connector you show has a shaft (ground) and a tip (signal). A stereo connector has an additional ring between the shft and the tip to carry the signal for the other channel. All walkman style headphones are like that.

I think I see it now, that's why it's got the two rings right?

I feel enlightened.

Exactly, the shaft, the ring, the tip. The lead you showed in the first picture doesn't have the ring.

That jack is also 1/4", the one you need is 3.5mm. You may be using a 3.5mm to 6.35mm (1/4") adapter.

blueSL, it's a slide on adapter on the headphones.

Uh, let me take a picture of mine actually, I just stole those off a website.
I guess this means I'll actually have to put clothes on...

Here's a few pictures.

Okay folks, you should use a plug such as the gold one, because it'll transmit stereo, unlike the one on the right (silver) because it'll only transmit one side; mono.
