Sony MDR-NC33: need noise-canceling pod

I've been sold a pair of the titular headphones. I wasn't told they had a noise canceling feature, and was expecting normal 'phones; I was therefore surprised at seeing the 5-pole jack. However, I was not sold the pod that does the noise-canceling calculations and has the standard 3-pole jack.

Turns out they're useable in most players by simply pulling the jack about a mm out, but my main player is now my phone, and I can't use them in that because it gets confused by the multipin jack, identifies them as a headset and inserts a very annoying intermittent noise.

So I need the pod, without the 'phones. Can this be found anywhere, and what expense am I looking at?

Thanks.

You're right, the seller does in fact have that player. He was obviously unaware that the 'phones were meant for that and that alone.

So, what do I do now? I really like the noise-canceling thing, but since the pod of the normal NC33s is one with the cable I can't hope to find one bare on which to solder mine.

Are there any third-party pods, or pods from other brands, that I could maybe adapt?
