This is a pair of the new iPhone or iPod headphones, called "Earpods" by Apple. The cords are rigged with an IK Constraint, so that you can twist it via a Target Bone at the bottom. (They are also set up for an IK Spline Constraint, although the controlling Curves are not included in this .Blend, and therefore you will need to create new ones.)
There is no male plug at the end of the cord, but instead the cord Material is set to disappear at the end. I apologize for this, although I expect it will be relatively easy for users to model new plugs.
They're not perfect, but they should be useful for many purposes. I hope you enjoy them.
Thanks to everybody who works on Blender and Blendswap, and God bless!
