I was a little annoyed with my mp3 player, in that I wanted to hang it around my neck but the wires weren't quite right.
One short section of electrical insulation and a bit of fiddling was all I needed.
Step 1: Materials
I now have some Skull Candy Ear buds, the original Sony things hurt my ears after about 10 min...
You need a small soft and flexible tube. I cut a bit of plastic insulation, but you could make one from tape or many other things
Step 2: Looping
This is simple, follow the pictures.
The looping gives a "necklace" and a section to adjust the length.
The headphones can be parked when out of your skull.
>Hang the wire around your neck, with the audio-jack and headphones pointing towards your feet.
>Pull a loop on the headphones-end through the tube.
>Push the audio-jack through the tube.
>Connect the mp3 player.
>Adjust the lengths of wire to suit.
>Where the L & R wires join / separate there is a black lump: push that into the tube to wedge the wires in place.
(Time for some bleeps...)
