NOBRAND KZ ZSX Restored Tech Blue UPC 333240765508

NOBRAND Restored Tech in Blue, UPC 333240765508. The KZ ZSX in-ear monitors use 12 drivers, six per earpiece. Each side pairs a 10mm double-magnetic dynamic driver with five balanced armature drivers. KZ's technicians tuned them for a balanced, full-bodied sound with fast, punchy bass, natural and detailed mids, and smooth highs without sibilance. The stated frequency response is 7Hz to 40kHz, with 111dB/mW sensitivity. The sound is described as having rich detail, a wide soundstage and precise imaging. Each shell combines a shiny zinc alloy cover and imported resin cavity, with metal edges finished to avoid sharpness. Other listed color options include purple, black and cyan. The compact, low-profile shape is intended to stay secure and comfortable during extended wear and active use. Some KZ ZSX variants offer noise cancellation to reduce external sound. Check the specific version, since active noise cancellation is not included in every model.
