KZ ZAS
The 7 balanced armatures and 10mm dynamic driver in each earpiece separate frequencies for detailed highs and deep bass, fed by a silver-plated 100-wire cable for transparent signal. The pearl chrome-plated zinc alloy shell resists oxidation and the ergonomic, round-tipped cavity effectively isolates noise without active electronics. Best for budget-minded audiophiles who want a bass-rich, wide-soundstage wired IEM for critical music listening, not call clarity.
