About IEM Upgrade Cables
IEM upgrade cables replace the detachable cable on in-ear monitors, either as an upgrade or as an after-sales replacement. The earphone end uses MMCX or flush 0.78 mm 2-Pin connectors with left and right marking and pre-formed heat-shrink ear hooks. Source plugs include 3.5 mm TRS, 4.4 mm 5-pole balanced, and 2.5 mm 4-pole balanced. Typical builds are 4- or 8-strand round braids of oxygen-free copper (OFC), about 26 AWG per strand, with soft PVC insulation in clear or black, at a length of 1.2 m (3.9 ft).
