The retractable earphone is a type of earphone cable that can be freely retractable and free to control the earphone cable as needed. The principle of this earphone design is to inject liquid gallium indium alloy into the elastic polymer tube, which can be normally conductive and free to stretch. When you need to use it, take out the earphone cable and start using it. When you use it, you can retract it. After retracting, the overall volume is small, it is particularly convenient to carry, and there is no trouble with the winding of the earphone cable.
