Overview
The details behind KZ PRX.
Experience Sound Like Never Before with KZ PRX
KZ PRX sets a new standard in audio with its groundbreaking planar technology, delivering exceptional sound quality that surpasses traditional dynamic and balanced armature earphones. The ultra-thin diaphragm enables precise vibrations, achieving a level of performance that traditional dynamic and balanced armature drivers struggle to match. An essential for hardcore audiophiles, PRX redefines the experience of musical companionship. Even as your passion for discovery fades, the PRX remains by your side, letting you enjoy pure melodies with effortless clarity.
Lighter Diaphragm Mass for Superior High and Ultra-High Frequency Extension
Compared to traditional dynamic and balanced armature drivers, the lightweight construction of the PRX planar diaphragm delivers unprecedented extension in high and ultra-high frequencies. This allows even the most delicate details to shine through, redefining the auditory experience.
What Defines a True Planar Driver?
In recent years, some drivers have been labeled as "planar" but differ significantly from true planar technology. A genuine planar driver is designed with at least 14 high-performance magnets and operates without a traditional voice coil, resulting in exceptional high-frequency extension and a wide soundstage. Unlike traditional dynamic drivers, a true planar driver features a uniformly electroplated voice coil coated with approximately 5μ of conductive silver. This innovation significantly reduces mass and inertia, allowing the diaphragm to extend high and ultra-high frequencies with greater precision.
Precision Craftsmanship for Unmatched Audio Performance
KZ is dedicated to the independent research and development of planar drivers, ensuring unmatched material craftsmanship that sets the brand apart. KZ's planar diaphragm, developed using an advanced silver-plated vacuum electroplating process and featuring a matrix of 14 N52 magnets, is meticulously crafted in every detail. This dedication delivers a truly exceptional audio experience that surpasses expectations.
The Acoustic Curve: Proof of Superior High-Frequency Performance
The acoustic curve is the ultimate proof of KZ PRX's exceptional engineering. It not only demonstrates the remarkable extension of high and ultra-high frequencies but also stands as the gold standard for evaluating sound quality, authenticity, and fidelity.
Fourth-Generation Planar Driver: Enhanced Sensitivity
The fourth-generation planar driver introduces a new level of audio quality. With improved sensitivity, PRX enhances the listening experience, offering clearer and more precise sound. Rather than simply evolving, PRX represents a thoughtful advancement in audio technology.
Comparison of Upgrades: PRX vs. PR3
Damping Structure Optimization: Significantly reduces sibilance for a smoother listening experience.
Acoustic Curve Optimization: Provides a more expansive and natural soundstage.
Magnetic Circuit Enhancement: Increases sound density, delivering richer and fuller audio.
Continuing the Classic Ergonomic Design
Every curve follows the natural shape, and every line showcases exquisite craftsmanship. This design not only honors the classic but also surpasses expectations, making wearing a pleasure and ensuring lasting comfort.
Professional-Grade OFC Silver-Plated Upgrade Cable
The PRX comes equipped with a high-purity silver-plated cable, enhancing conductivity and ensuring more stable sound signal transmission for an improved audio experience.
Multi-Function Single-Button Control for Easy Operation
The built-in microphone delivers clear and precise sound pickup, providing a call experience that feels as natural as a face-to-face conversation.
Environmentally Friendly Packaging
KZ believes that great products don’t need extravagant packaging, as true performance speaks for itself. Committed to environmental protection, KZ avoids profiting from environmentalism, staying true to this core belief since its founding.

What listeners say about sound, fit and everyday use.
Got this iem at a good very price great quality love the sound,great delivery took a bit time but they delivered safely thank you
Excelent imaging, trebble and bass. In gaming it's quite good and not fatiguing. I can hear footsteps quite clear and from afar. They are not harsh to ears as Truthear Pure or AS16proX. I also paired them with the KZ 8 core gold silver copper cable and it adds more resolution at higher volume and thing are not muddy as with stock cable.
Don't buy gaming not to gud
Hello there,
Thank you for your feedback.
We're sorry to hear that you did not have a great experience with our product. We would love to understand what specific issues you faced so we can improve.
Feel free to contact us anytime at support@linsoul.com. We will do our best to assist you.
Thank you for your time.
IE-Planar with wide and detailed soundstage, low end bass capability, crispy highs and present mids.
Foam-pluggs are a must (size M is included), silikon-pluggs sound horrible.
Changing the wire to balanced one and drive them with a preamp, helps a lot - I use the powerdac from e1da with Vinyl-EQ setting (+4 bass and +6 treble) to enrich the neutral sound.
Padcast, vocals, classic and pop-music are played in very good quality for the price but can´t replace/match a over ear on boddy of sound like Grado SR225.
This iem is a perfect machine for retro style musics from the '80s/'90s. Like most planar iems, it's also got very good clarity and separation, but there is a bit of saturation that adds a bit of retro taste, making it perfect machine for city pop musics. I would say it's definitely worth spending some time trying with different custom cables, eartips or even with some tube amps to upgrade it's unique character.
