Once, the wires are finely soldered getting support of the flat jawed pillars, carefully inspect if any of the two wires are interconnected while soldering. If you find any of two wires are soldered together, make sure to wipe the connected solder line off carefully and at the minimum attempt possible. More attempt means weakening the rubber divider between jack compartments and exposing more to internal short-circuit.

Once done, make sure that exposed wire will be covered by squeezing the cable towards the edge of the jack. This is a fine trick but do not squeeze too hard since you may break the wire itself.

It's very insightful to spray non conductor element or just simply use clear tape to avoid short circuit between exposed and soldered wire-spots. Usually, if you are 100% sure about your fine work, you can simply drop a tinny bit of superglue over the soldered spots. But it may take unto 10 minutes to dry up completely. If you have non-conductor spray or tape, you may spray or affix it to secure your work.

Now push the jack into the iBeats metal exterior spraying quick dry fixer inside the metal exterior so that once the jack is inserted, it resides there firmly. Then push the Rubber Cable Support piece into the other end of the metal exterior the same way.

If you observe the picture closely, you may see a little gap between the cable holder and iBeats metal exterior. If you spray quick fixer well and pushed hart, you not gonna see that gap any more and your iBeats will look seamed properly. This will give your work a professional or refined look and feel.
