Combining (Rewiring) Earphones Together

[lazda]

Hello!

I'm having trouble rewiring my Ipod earphones.
Currently I have two sets of nonworking earphones.
One is an Ipod 3rd generation earphones. Pretty standard, ones you can find anywhere.
The earbuds are completely busted on this one, and thus it does not work.

The second one is Iphone earphones, and thus has a little mic component along the right earphone cord. This one, the bottom jack is completely busted.

What I want to do this cut and combine the bottom 1 inch (including the jack) of my ipod earphone with my Iphone earphones.

I understand this will render the mic capability useless.

The ipod earphones have 4 wires inside, yellow, red, green, and red/green.
The iphone ones have 6 wires. green, blue, yellow, red, red/yellow, and another yellow.

How do I match these up to work? Thank you so much in advance!
