KZ EDZ
Final Chapter Collector's Edition
KZ Self-Developed Ultra-Wide Frequency &
Ultra-Excursion Dynamic Driver + Dual Damping System

The upgraded KZ EDX Series introduces the all-new KZ EDZ
An evolution of the KZ EDX Series, refined with upgraded acoustics and enhanced sound clarity.
Building on the classic acoustic foundation of the KZ EDX Series, the KZ EDZ features an innovatively upgraded dynamic driver that delivers richer, more textured vocals and a smooth, crystal-clear high-frequency response. The newly integrated dual damping system effectively suppresses harsh sibilance, restoring a purer and authentic sound. Every melody is reproduced with exceptional detail and clarity.
Ultra-wide frequency dynamic driver
Self-developed ultra-wide frequency and ultra-excursion driver that completes the EDX Series evolution.
The KZ EDZ incorporates the latest ultra-wide frequency and ultra-excursion dynamic driver, delivering an expansive frequency range from deep, powerful bass to crisp, detailed highs. This advanced driver captures subtle emotions and dynamics in your music, effectively redefining the standard for HiFi sound quality.
Dual-stage damping system
Precise sibilance control for a more natural and pure sound.
Precise control of sibilance is crucial for achieving a natural sound. The KZ EDZ features a dual-stage damping system that combines nozzle tuning dampers with a metal sound filter. This design effectively reduces harshness while preserving crucial sound details.
Ultra-wide frequency response
7–45,000Hz range with high sensitivity and fast transient response for lossless-level detail.
In music, every detail matters. The KZ EDZ features an ultra-wide frequency response of 7Hz–45,000Hz, allowing it to capture subtle nuances with high sensitivity. The result is an unexpectedly immersive listening experience, characterized by precise detail and clarity.
Ultra-stroke bass performance
Massive dynamic bass boost for stronger impact and control.
The magnetic circuit in the ultra-long excursion driver utilizes high-performance neodymium magnets to generate a stronger magnetic field, thereby increasing the driving force on the diaphragm. This stable, powerful field enables the diaphragm to move precisely with low-frequency signals, allowing it to start and stop quickly. The result is bass that's tight, punchy, and impactful.
Benchmark acoustic tuning
A reference-grade tuning curve that rivals far more expensive IEMs.
Breaking the price-to-performance barrier and brand premium barrier. While many $100+ IEMs settle for "just usable," the KZ EDZ's benchmark acoustic tuning delivers audio quality that outclasses higher-priced models. At an accessible price, it offers a pro-grade listening experience where every investment is directly dedicated to sound.

Pro-grade dual-mic cable
Optional dual-microphone cable for clearer voice capture and in-game communication.
We adopted a high-definition dual silicon microphone array to improve voice pickup accuracy. Compared to conventional single-microphone cables commonly used in gaming headsets, this setup captures human voices with greater precision, ensuring clear and reliable communication during gameplay. The microphones are positioned at both the top and bottom based on real-world usage scenarios. Even when the headset hangs naturally, audio pickup remains consistent. This design helps reduce plosives and distortion, delivering a balanced combination of performance and everyday usability.
Optional wireless Bluetooth module
Instantly converts wired earbuds into a wireless setup without compromising sound quality.
Designed for seamless switching between wired and wireless use. Simply plug in the Bluetooth module to go wireless and remove the cable connection. With benchmark acoustic tuning and ultra-stroke drivers, this setup delivers sound quality that challenges conventional wireless earphones, offering a more engaging and natural listening experience.
Optional silver-plated upgrade cable
Integrated pro-grade filter for adjusting treble and bass to your preference.
This optional silver-plated cable features an integrated professional-grade filter designed for sound customization. Easily adjust treble and bass output to match your listening preferences, allowing you to fine-tune the sound signature to suit different music styles and use cases.
* Note: Built-in sound card is only available for the Type-C plug version; the 3.5mm plug version does not include one.

Classic, minimalist, eco-friendly packaging
A gentler choice for every life on Earth — putting every cent where it truly matters: into the product itself.
Our product doesn't rely on luxurious packaging to enhance its appeal, because true performance and real quality cannot be reflected through packaging alone. We advocate environmental protection, but we do not use it as a pretext for higher profits. This belief has been part of KZ's philosophy since the brand was founded. Never forget the pure joy music brings to your soul.
