Where to find 3.5mm (male) to 3.5mm (male) cable that can control iPhone/iPod volume 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.
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.
