This question is different from the one where the metal wire breaks.

It's been a few years since I've used these earphones of my phone, and now the plastic is beginning to crack at multiple points, exposing the metal wire (but there is no problem with the functionality of the earphones. It's functioning fine).
enter image description here

I've tried wrapping cello-tape and insulation tape around it, but the tape never stays in position. It keeps sliding sideways, exposing the broken plastic and wire again.

Is the only solution to get a new pair of earphones or is there a way to fix the plastic.

  • Electrical tape is the black wrapping you see in the pic. It doesn't stay in place. Heat shrink wrapping I've never tried, but I Googled it and it seems like it's meant for larger objects. Would you actually use it on earphone wires? The wire's plastic is breaking at multiple points.

Use heat shrink instead of tape. That won't slip around after it shrinks around the damaged area.
