About Modular Interchangeable-Plug Cables
A modular headphone cable has a detachable plug module at the player end, so one cable works with single-ended and balanced sources. The stock design pairs an 8-strand braided IEM cable with MMCX or flush 0.78 mm 2-Pin connectors and three swappable modules: 2.5 mm 4-pole, 3.5 mm TRS, and 4.4 mm 5-pole. Strands are oxygen-free copper (OFC), about 26 AWG each, with soft PVC insulation; the modules have aluminum-alloy housings and gold-plated contacts. The cable is 1.2 m (3.9 ft) including the module, and it ships in a pouch or case with slots for the modules.
