Repairing exposed wires on a wireless earbuds (Jaybird X3)

[Kn9]

I have been using the Jaybird x3 for more than a year now and it has been such good daily and workout audio device. Unfortunately the wire of the earbuds is starting to tear everytime i use it when I workout or whenever I use it on my everyday commute.

I would like to know any good methods to covering up wires in a wireless earbuds since I am not sure how sensitive the wires are.

Is it just the insulation? I once fixed mine using a piece of heatshrink tubing I had laying around.
