Every time before I listen to the music ，it takes me some time to untie the earphone cord tangled up，which makes me feel bad 。Inspired by the invention of the simple seal bag，I designed this earphone that can conveniently bond two cords into one by the using the mutually jamming character of concave-convex。The earphone cord will never tangle up again。
