I found it really easy to shorten the cable. I like the short cable much better for the way I use the headphones and it’s much lighter than a coiled cable.

First take of the earpad on the left side and take out the four screws under it. When they're out you can pull the two halves of the earcup apart and rotate the driver to the side like earfonia showed. Next write down what order the colored wires are in on the circuit board (or look at earfonia's pic) and unsolder those three wires from the board. Unwind the thick black cable from around those two posts in the earcup so you can pull the cable out through the strain relief in the ear cup and cut straight though the cable at whatever length you want. I use mine at my desk as well as portably so I cut mine at about 4.5’ from tip to cut. The cable hangs down almost to my ankle though so 3.5’ would probably be a good length for pockets or even shorter. Maybe try taping the cable to the side of the headphones and using them so you can see what the perfect length would be, make sure you leave 10cm extra for the part that goes into the headphones if you do it this way. Once you have it cut you need to strip about 5cm of the black plastic cover off the end and leave the insulation on the three smaller cables inside intact. Then you need to strip of about 5mm of the colored insulation from the ends of each of the colored cables, leaving the copper wire ready for soldering. Put the cable back through the strain relief and solder it to the circuit board in the correct order. Wrap the cable back around the posts and put it all back together. It's really simple.
