The ZSX combines a zinc alloy faceplate with a resin cavity, using a 5 balanced armature + 1 dynamic driver hybrid configuration (two BA drivers for mids/highs, one dedicated high-frequency BA, and one dynamic driver for lows). The detachable 2-pin cable is gold-plated with a pin-protection design intended to extend connector lifespan, and the shell shape is designed around ear-canal data for a closer fit.
