KZ ZSX 1DD+5BA Hybrid (12 Drivers) HiFi In-Ear Monitor — 10mm Double-Magnetic Dynamic + 5BA per Side, Metal Noise-Cancelling Earbuds

Driver configuration: The KZ ZSX uses a hybrid arrangement totaling 12 drivers (six drivers on each side). Each earpiece pairs a 10mm double-magnetic dynamic driver with five balanced armature drivers to cover a wide sonic range. Sound signature: Tuned by KZ’s professional technicians, this model delivers a balanced, full-bodied presentation. The 10mm dynamic unit supplies fast, punchy bass while the five balanced armatures per side reproduce natural, detailed mids and smooth, non-sibilant highs. Frequency response is 7Hz - 40kHz with a sensitivity of 111dB/mW, producing rich detail, wide soundstage and precise imaging. Build and finish: The shells combine a shiny zinc alloy cover with an imported resin cavity for a lightweight yet premium feel. Metal edges are finished to be anti-cut, resulting in an elegant overall appearance. Available color options include purple, black, and cyan. Ergonomics and fit: The ZSX has been ergonomically redesigned into a compact, low-profile shape for a secure, comfortable fit. Its form improves stability during extended wear and active use, reducing the chance of falling out. Noise isolation: Certain KZ ZSX variants include a noise-cancelling feature that helps block external sounds for a quieter listening environment. Note that not every model includes active noise-cancelling — check the specific version for this capability.
