I first measure 4 equal length wire, solder then onto the 3.5mm plug. then I thread the wires through the sleeve. heat shrink was used to fix the sleeve to the wire before puting the cover of the plug onto it. another layer of heat shrink to the external of the plug. on the other end, the four wire was twisted into two pair each has one signal and one ground. then I use heat shrink to fix the twist at the beginning of the twist so it become a Y-end cover with another layer heatshring. I also use a short pieces of heatshrink to hold the twist at the end of both left anf right wires twist the goes into the headphone. this complete the wire part.as for D2000, taking it apart is easy. The earpad was twisted on, no glue no screw, so a correct twist will remove the earpad to expose the screw that hold the driver unit to the headband. unscrew the 8 screw you will see after taking away the earpad. now you have tyhe driver exposed. unsolder the wire, untied the knot that Denon uses as strain relieve then the wire can be slide off easily from driver unit housing and headband. now do the reverse of removal of original wires using the cable just made, put it back together you will get a recabled D2000, very easy.
