The KZ ZST utilizes a 1DD+1BA hybrid driver configuration to provide a V-shaped sound profile, which is characteristic of entry-level Chi-Fi IEMs. While the hybrid architecture offers distinct separation between bass and treble, the build quality and cable longevity are common points of concern for this aging model.
Best for listeners seeking an affordable entry into hybrid-driver audio who prioritize bass-heavy sound signatures over premium build materials.
