Yamaha YH-4000 Premium Open-Back Headphones

The YH-4000 inherits the design and engineering prowess of our flagship YH-5000SE yet offers a distinctive sound signature of its own.
Providing a more intimate interpretation of the Orthodynamic experience, it reveals the presence and passion of every performance through
exceptional clarity and depth. Designed for effortless, extended listening, it invites dedicated music enthusiasts to rediscover the allure of
Orthodynamic sound in an exciting new way.

Yamaha occupies a truly unique position in the global audio industry, deeply involved in every stage from music creation to the moment it
reaches the listener. The YH-4000 places you directly in the front row of the performance, delivering a profound musical experience filled with
dynamic realism and spatial expressiveness. Experience vocals alive with genuine emotion. Feel the driving pulse of drums and bass. Sense
the delicate ambience of a live performance — capturing the shared energy between artist and audience.

TONAL BALANCE

Orthodynamic drivers and spacious housings reproduce sound with remarkable accuracy, delivering high-density, natural audio across
the full sonic spectrum. Every vocal and instrument is faithfully rendered with precise timbral integrity. The result is powerful, lifelike sound
quality that draws you deeply into the music.

FULLY COMMITTED TO SONIC ACCURACY:
OUR UNIQUE ORTHODYNAMIC DRIVER

In the 1970s, Yamaha introduced the planar magnetic Orthodynamic driver —
beginning with the HP-1 — which earned acclaim from audiophiles worldwide.
The YH-4000 features a redesigned Orthodynamic driver, modernized using
advanced technologies. By intentionally omitting the sound absorbing material
featured in the flagship YH-5000SE and meticulously tuning every detail, we’ve
achieved a uniquely responsive, natural and precise Orthodynamic sound.

NUANCED MUSICAL DETAIL & EXPANSIVE SOUND
FROM OPEN-BACK HOUSINGS

The generously sized housings wrap comfortably around the ear with an
open-back design that provides substantial internal acoustic volume.
This configuration optimizes airflow, allowing the thin-film diaphragm to
operate under ideal conditions, effectively eliminating unwanted resonance
from reflected sound within the rear cavity. A newly developed PET mesh
filter precisely regulates internal housing pressure, while an arch-shaped
protrusion acts as a reflector to further enhance sonic accuracy. Together,
these innovations deliver natural instrument and vocal reproduction, capturing
delicate sonic expressions clearly, from initial note to gentle decay.

DYNAMICS

The YH-4000 goes beyond sheer power, faithfully preserving the contrast between silence and motion in music. From subtle textures to bold
low-end impact, it delivers fast, precise response with rich detail. This level of control and expression allows the listener to experience the full
energy and nuance of the performance.

ULTRA-LIGHTWEIGHT, THIN-FILM DIAPHRAGM
FAITHFULLY RECREATES MUSICAL DYNAMICS

The diaphragm features conductive coils on both sides and finely corrugated
wave-like patterns across its surfaces. Far lighter than a conventional dynamic
driver, it responds with remarkable precision, revealing subtle nuances and
airy detail in every performance. Micro-perforation air dampers on both sides
control movement with care, preserving the natural dynamism of music without
distortion or loss of energy.

SOUND IMAGE

From the openness of concert halls to the intimacy of small clubs, the YH-4000 faithfully reproduces spatial detail and sonic ambience. You
can sense the position of each performer and even their subtle movements as if you were right there in the room, watching the performance
unfold before you.

SOUND WITH REMARKABLE SPACIOUSNESS AND DENSITY

To achieve a dense midrange and tight, punchy low-end while preserving
a spacious and open sound, a Japanese-made PET mesh filter is used to
precisely regulate internal housing pressure. After evaluating a range of finely
woven materials with varying airflow characteristics, we selected the filter with
ideal permeability to match the sound vision for the YH-4000. The result is a
sound that fully conveys the passion and energy of every artist.

EAR PADS FOR DEEP IMMERSION IN THE MUSIC

Developed exclusively for the YH-4000, these premium ear pads combine two
materials: high-quality artificial suede on the inner surface and exceptionally
flexible polyurethane leather around the outer edge. This hybrid construction
blends the warmth of suede with the resolution and control of leather. Fine
perforations across the entire surface contribute to a spacious, open sound.
The soft, velvet-like texture and gentle cushioning create a comfortable,
enveloping feel that is ideal for extended, immersive listening.

FINE QUALITY, COMFORTABLE WEARABILITY

Lightweight construction and refined design make the YH-4000 so comfortable and easy to wear, you may forget you have them on. This
effortless fit enhances extended listening sessions and allows you to immerse more deeply in the music with both comfort and style.

SLIM, COMFORTABLE AND LIGHTWEIGHT MAGNESIUM BODY

The housing frame is made of magnesium, a metal known for its excellent
vibration damping properties and high structural rigidity. Despite its strength,
the body remains lightweight at just 320 grams (11.3 ounces), making it
comfortable and unobtrusive even during extended listening.

TWO-LAYER HEADBAND WITH SMOOTH, STEPLESS SLIDER

The headband features a solid stainless-steel arm that showcases the
material’s refined texture while applying optimal lateral pressure to minimize
fatigue on the ears and head. The head pad uses a three-dimensional weave
with moderate thickness to flex naturally and evenly distribute pressure.
The stepless slider allows for precise, personalized adjustment to ensure a
consistently comfortable fit.

INCLINED SWIVEL MECHANISM

To prevent air leakage and preserve rich low-frequency response, it is critical
that the housing fits securely behind the ear. The YH-4000 achieves this
with an inclined swivel mechanism that tilts the rotation axis, allowing subtle
vertical movement to stabilize surface pressure. This snug, comfortable fit
enhances both acoustic performance and overall listening enjoyment.

QUALITY THAT INSPIRES PRIDE IN OWNERSHIP AND USE

The YH-4000 reflects the full breadth of Yamaha’s craftsmanship and design sensibility, created to be used with pride and cherished over
time, like a finely made musical instrument. Every detail has been carefully considered, with no compromises, resulting in a sense of prestige
that befits a high-end model.

ATTAINING FUNCTIONAL BEAUTY
THROUGH DESIGN AND TEXTURE

The design has been reduced to its essential form to express the energy and
movement inherent in music. A bold open gap in the housing is protected by
a triaxial woven mesh, a material widely used in the aerospace industry. The
YH-4000 is built around the concept of functional beauty, with premium
materials chosen for both performance and appearance. Every component
reflects our commitment to purposeful design and refined craftsmanship.

HANDMADE BY SKILLED CRAFTSMEN IN A
EXCLUSIVE FACTORY FOR FLAGSHIP MODELS

From driver construction to final assembly, the YH-4000 demands exceptional
technical skill and precision. That’s why it is produced at our Kakegawa factory,
the same facility that builds our flagship grand pianos and audio components.
Each unit is carefully assembled by skilled craftsmen under the highest standards
of quality control.
