The KZ Sonata X is a wired IEM with 14 balanced-armature drivers per side, an electronic 4-way crossover and four tuning switches that lift the bass or trim the ultra-highs by 1–2 dB. It suits listeners who like to fine-tune their sound and gamers who want one set for music and mic chat.
Who the KZ Sonata X is for
Sound tweakers: Four switches raise the bass by 1 or 2 dB or pull the ultra-highs down by 1 or 2 dB, so you can shift the balance without buying a second set.
Multi-driver BA fans: Each side runs 14 balanced armatures — ten for ultra-highs, one mid-high, two mids and a second-generation 22955 for bass — split by an electronic 4-way crossover.
Gamers and callers: The second, silver-plated cable carries a dual 6 mm condenser-mic array with inline controls, so the same IEMs handle voice chat and calls.
Dongle, DAP and PC listeners: With a 24–28 Ω impedance it runs from a USB-C dongle, a DAP or a gaming setup's headphone output.
Skip it if: your source is 4.4 mm balanced: both included cables end in a 3.5 mm plug, so balanced use means buying a separate 0.78 mm 2-pin cable.

vs EPZ K9: K9 is a 1DD + 8BA hybrid with a modular 3.5/4.4 mm plug; choose it for a balanced 4.4 mm source, or the Sonata X for an all-balanced-armature build.
