Loop Cable / Earphone

Loop Cable
Loop Cable

It takes us a long time to twine our earphone's wire, or will be mad to deal with a wire ball.
A theory called "Loop Conjecture" says that line wire is more risky of knotting than a ring one.
It only needs one operation when tidying a "Loop Cable" wire: press the wire on the plug side into two snap joints on the back of earphones to form a ring.
