Just a quick guide to show how i made an adaptor out of the original G1 headphones for 3.5mm headphone jack.
First off just some background
Above is "EMU" connecter (EMU stands for Enhanced Mini USB) this connector is pretty much the same mini-b USB connector except EMU also has an audio channel.
In the above image:
Data
A = GND
B = NC
C = +DATA
D = -DATA
E = +5v Audio
1 = +Mic
2 = +Right
3 = Switch
4 = Gnd
5 = Gnd
6 = +Left
Now for the creation of the adaptor:
1) Cut the cable as near or far away from the EMU as you like (i made my adaptor about half a foot long in case i had to start again)
2) Strip the cables and split them apart
1 Mic = white
2 +right = red
3 switch = blue
4 ground = blue/copper
5 ground = copper
6 +left = green
A ground = red/copper
3) Next up you'll have to find a 3.5mm headphone jack to use (i work for a laptop repair company so i just got one off an old mainboard)
4) On the picture above you can see where you need to solder the the left and right speaker ( please excuse the inaccuracy of the image BLUE in this case is ment to be GREEN, and the BLACK PCB wires are GROUND/EARTH)
Just a note that only one ground is really needed, i used PCB pin 2. Also, this guide is ONLY for headphones, if you want to use the other features of the EMU (like mic) you will also have to connect those and use a diffrent type of 3.5mm jack.
5) Now just seal the wires with some hot glue and cover it with some heat shrink and its all done!
Please post any questions and please point out if ive missed anything.
Pictures of my finished product to come! Please also excuse any spelling/grammer errors and the poor english in the subject line
