The Line Cap is both decorative and practical. It can plug into smartphones to jazz them up and it can also act as a cord organizer. The latter entails a person winding up their headphone wire and placing it in the cap out of sight when not using it. When it is in use, the Line Cap can rest anywhere on the cord, continuing to spice things up even if it isn't plugged in itself.
Created by Sumneeds, the same company that brought people the Line Tail, the Line Cap is much more urban. It takes on the shape of a fullback hat. Although this would appear to appeal to men, it comes in a variety of colorways that will also attract women. The Line Cap is made out of silicon for flexibility.
