SE Earphone Cable RemovalFAQ #4432
The cable/earphone connector is difficult to remove, and designed like this on purpose.
Grasp the earphone using a piece of cloth, like the T-shirt, between your fingers and the earphones. Do the same with your other hand, using a piece of cloth, on the connector. Then pull apart: do not twist or rock back and forth. It takes 20 to 30 pounds of force to separate the two parts of the connector.
