YH-4000
Combining precision craftsmanship with premium materials, the YH-4000 headphones set a new benchmark in authentic sound reproduction.
At their core lies Yamaha’s signature Orthodynamic™ driver, revealing the presence and passion of every performance through exceptional clarity and depth. Designed for effortless, extended listening, the YH-4000 invites dedicated music enthusiasts to rediscover the distinctive allure of Orthodynamic™ sound.
The 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.
Open-Back Housing
The generously sized housings wrap comfortably around the ear with an open-back design that provides substantial internal acoustic volume. This configuration optimises airflow, allowing the thin-film diaphragm to operate under ideal conditions and 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.
Ultra-Lightweight Diaphragm
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.
PET Mesh Filter
To achieve a dense midrange and tight, punchy low-end while preserving a spacious and open sound, a 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 artist’s passion and energy.
Exclusive Ear Pads
Developed exclusively for the YH-4000, these premium ear pads combine two materials: high-quality artificial suede on the inner surface and exceptionally flexible PU 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.
