KZ ZSN Pro X Hybrid Earphones

The KZ ZSN Pro X combines four balanced armature drivers with one dynamic driver in a single in-ear housing. Two 30095 armatures handle high frequencies while two 50060 armatures cover the midrange. A second-generation Tesla double magnetic dynamic unit provides bass response. The design targets listeners who want detailed separation across the frequency range.

Stainless Steel Faceplate and Detachable Cable

A 304 stainless steel faceplate pairs with an imported resin cavity for durability and a secure fit shaped from cochlear data. The gold-plated 2-pin connector is detachable for cable upgrades and includes a limit slot to protect pins from damage. Passive isolation reaches 26 dB, reducing ambient noise during commuting or exercise.

PCB Frequency Dividing Board Under Load

An internal PCB frequency dividing board coordinates the five drivers to maintain coherent output during extended listening sessions. The crossover keeps high-frequency extension beyond 40 kHz controlled while preserving dynamic low-frequency impact. The ergonomic shell stays seated during movement, so driver alignment and isolation remain consistent over long periods.
