You will need these beads. I got them in the craft store for very cheap :)

My earphones. I chose earphones but you could use your charger :)

A scissors :)

You do not need this but I found it was very handy when opening the beads :) you could use a scissors instead of this :)

Cut the middle of the bead :)

You can use your scissors as well for this part. Put it into the middle of the bead.

Attach it to the earphones :)

You need to be very patient but it is worth it in the end :)

So that's how I customised my earphones :) I hope you found this guide handy, if you did please like and comment. You can even follow me :) thanks so much :) if you have any questions just comment :)
