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

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.

Solution 1:

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

Solution 2:

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.

Solution 3:

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!)
