The FF1 comes with a 0.78mm 2-pin detachable cable. It adopts the recessed 2PIN connectors in order to protect the 0.78mm 2-pin structure and reduce the possibility of broken or bending. But it is not guaranteed to be compatible with the 0.78mm 2-pin cables on the market due to the limit of the structure. The FF1 will be compatible with the FiiO-designed headphone cable, which is still under development.
