Help Me Find A Cord Winder for Headphones?

Hi 'dopers. My friend suggested I should post this here.

I’m usually great at searching the 'net, but I’m beat.
I am looking for a cord winder that is spring loaded to use with headphones or other small(ish) cords.

I’ve found:
Simple cord winders with no springs:

Headphones with spring loaded cord winder:

But I’m just looking for a spring-loaded cord winder so I can put in any cord I want. I don’t want to buy a cord installed in the winder. Any suggestions?
