Make a headphone cord manager with something that you already have in your work bench. If you already don't know how to do it from the picture, read on.
Step 1: Secure the Solder Wicks Spool.....
Well....go find some solder wicks either from you workbench, or from you work,...go ask the guys/gals that work in the electronic rework area. Somebody will have one that's almost spend.
You can buy these spools of Solder Wicks from Radio Shack, FRY's, or any other electronic shops...or buy the solder wicks online. It costs like $2 and up.
Unwrap the whicks from the spool, and wrap it onto another spool(Don't waste now) or store it somewhere for use later.
Step 2: Wind the Headphe Wires on to the Spool.
Flip the thing open like them pictures, and wind your headphone on to it.
Step 3: Flip Close the Spool.
