Designed for effortless, extended listening, these premium headphones invite dedicated music enthusiasts to rediscover the allure of Orthodynamic sound in an exciting new way.\u003c\/p\u003e\n\u003ch3\u003eTRUE SOUND\u003c\/h3\u003e\n\u003cp\u003eYamaha 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.\u003c\/p\u003e\n\u003ch2\u003eTONAL BALANCE\u003c\/h2\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eFULLY COMMITTED TO SONIC ACCURACY: OUR UNIQUE ORTHODYNAMIC DRIVER\u003c\/h3\u003e\n\u003cp\u003eIn 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, Yamaha achieves a uniquely responsive, natural, and precise Orthodynamic sound.\u003c\/p\u003e\n\u003ch3\u003eOPEN-BACK HOUSINGS FOR NUANCED MUSICAL DETAIL \u0026amp; EXPANSIVE SOUND\u003c\/h3\u003e\n\u003cp\u003eThe 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 and effectively eliminates 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.\u003c\/p\u003e\n\u003ch2\u003eDYNAMICS\u003c\/h2\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eULTRA-LIGHTWEIGHT, THIN-FILM DIAPHRAGM FAITHFULLY RECREATES MUSICAL DYNAMICS\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch2\u003eSOUND IMAGE\u003c\/h2\u003e\n\u003cp\u003eFrom 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.\u003c\/p\u003e\n\u003ch3\u003eSOUND WITH REMARKABLE SPACIOUSNESS AND DENSITY\u003c\/h3\u003e\n\u003cp\u003eTo achieve a dense midrange and tight, punchy low-end while preserving a spacious and open sound, Japanese-made PET mesh filters are used to precisely regulate internal housing pressure. After evaluating a range of finely woven materials with varying airflow characteristics, we selected the filters with ideal permeability to match the vision for the YH-4000. The result is a sound that fully conveys the passion and energy of every song.\u003c\/p\u003e\n\u003ch3\u003eEAR PADS FOR DEEP IMMERSION IN THE MUSIC\u003c\/h3\u003e\n\u003cp\u003eDeveloped 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.\u003c\/p\u003e\n\u003ch2\u003eFINE QUALITY. COMFORTABLE WEARABILITY.\u003c\/h2\u003e\n\u003cp\u003eLightweight construction and refined design make the YH-4000 so comfortable and easy to wear, and so comfortable you may forget you have them on. This effortless fit enhances extended listening sessions and allows you to immerse in the music with both comfort and style.\u003c\/p\u003e\n\u003ch3\u003eSLIM, COMFORTABLE, AND LIGHTWEIGHT MAGNESIUM BODY\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eTWO-LAYER HEADBAND WITH SMOOTH STEPLESS SLIDER\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eINCLINED SWIVEL MECHANISM\u003c\/h3\u003e\n\u003cp\u003eTo 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.\u003c\/p\u003e\n\u003ch2\u003eQUALITY YOU'LL NOTICE WITH EVERY USE\u003c\/h2\u003e\n\u003cp\u003eThe YH-4000 reflects the full breadth of Yamaha craftsmanship and design sensibility, created to be used with pride and cherished over time. Every detail has been carefully considered, with no compromises, resulting in a sense of dignity that prestige a high-end model.\u003c\/p\u003e\n\u003ch3\u003eDESIGN AND HIGH-QUALITY TEXTURE: ATTAINING FUNCTIONAL BEAUTY\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eHANDMADE BY SKILLED CRAFTSMEN IN AN EXCLUSIVE FACTORY FOR FLAGSHIP MODELS\u003c\/h3\u003e\n\u003cp\u003eFrom driver construction to final assembly, the YH-4000 demands exceptional technical skill and precision. That is 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.\u003c\/p\u003e\n\u003ch2\u003eACCESSORIES\u003c\/h2\u003e\n\u003cp\u003eTo ensure the best possible listening experience, the YH-4000 comes with carefully chosen accessories. These include an audiophile-grade cable with silver-coated OFC, custom ear pads made from premium materials, and a protective carrying case that shields the headphones from impact and keeps them clean.\u003c\/p\u003e\n\u003ch3\u003eHeadphone Earpads\u003c\/h3\u003e\n\u003cp\u003eThe ear pads combine a luxuriously textured artificial suede on the front and highly flexible PU leather on the sides. Together, they combine the warmth of suede with the resolution of leather, and the entire surface is finely perforated to create a spacious sound.
