Bonus if it has a mic and can handle iPhone calls

Basically I have a snowboarding helmet that has speakers built into it and has a 3.5mm (female) connection to the speakers.

I can't vouch for it, but it looks like what you're asking for :-)

This indeed looks right. –  CajunLuke Jun 8 '12 at 16:44

If you'd also want to skip the cable itself, I would suggest taking a look at the Jabra BT3030 Bluetooth "Headset", which you could connect with any male-to-male cable.

There are such on ebay.com, I saw one today searching for "4 conductor 3.5mm [extension] cable" - I agree, they are rare. (You might have to build it yourself by buying two iPod earphones and then soldering the four cables, but I hope that's not necessary!)

The OP would want a cable with four conductors (TRRS) in one end and three (TRS) on the other. The helmet doesn't itself have volume controls or a mic. –  CajunLuke Jun 8 '12 at 16:42
