After having my iPod ruined by an adapter that somehow broke and stuck inside the iPod, I decided it was time to just change the plug entirely, seeing as I never use the 1/4" one anyway.
So I got myself a Neutrik tiny plug (3,5mm right-angle), and looked at the instructions which shows three wires inside the cable, and how they're supposed to be soldered onto the connector. In my Sennheiser cable, there are four wires. Does this mean I can't use the Neutrik plug, or how do I solve this? I've soldered a whole bunch of stuff before, it's just the first time I do something audio-related.
 
Appreciate your help!

There are two wires for each driver. Positive and negative for each channel. You solder:
*two negative wires together (they might be same colour or looking the same) at Sleeve of the TRS jack,
*right positive (usually red) to Ring and
*left positive (white or black) to Tip.
 
Or take look at how was it done on old 1/4 jack, if you still have it.
Hope it helps.

Yeah it helps, you confirmed that I did everything right. Thanks!  =]

The two wires for each driver are actually Signal & Ground, not positive and negative.
