The Neotech NECH-3001 is a headphone cable made of 4 multi-strand UP-OCC Copper Litz conductors with PVC insulation and a Nylon braided outer jacket.
Litz means that each strand of copper is polyurethane coated; this reduces the impact of the skin effect and the proximity effect - great for audio, but the coating must be removed before a good solder joint can be achieved. This is best achieved using flux and a solder pot to tin the ends. Alternatively, tin your soldering iron with lots of solder and run the wire through the solder on the iron, the coating will melt and you can scrape it off.
Overall diameter: 3mm
Conductor with insulation: 0.9mm
Copper conductor: 0.6mm
A multimeter is essential to use this cable to identify the conductors. The cable is built up of 4 conductors 2 red and 2 blue. The cable is not shielded
The 4 conductors are made up of the same thickness and number of strands. Wire them as detailed below. Where there is only one point for the earth join on your plug / socket join the right and left earth wires together.
Left channel signal - 1 x blue
Left channel earth - 1 x blue
Right channel signal - 1 x red
Right channel earth - 1 x red
