KZ ZAS
The 10mm dynamic driver paired with seven balanced armature units creates a wide sound field and precise transient response across frequencies. Its 36 dB noise isolation and detachable 200-core silver-plated cable maintain signal clarity while the over-ear fit keeps it secure during movement. This IEM suits stage performers and budget-minded audiophiles who need analytical monitoring for instruments and vocals, not hands-free calls.
