Final A10000 | Dynamic Universal IEMs

Final Audio's A10000 Pairs a Solid Diamond Diaphragm with Finely Machined Housing to Deliver Ultra-Low Distortion and Exquisite Clarity Solid diamond diaphragm for high rigidity and minimal surface deformation Features new custom Polyurethane edge Uses vacuum and thermal molding for seamless molecular bonding Wave pattern design borrowed from luxury watchmaking ePTFE shielded silver-coated cable with in-house MMCX connector + 4.4mm plug Limited edition Collector's Edition available, only 300 units worldwide The Ideal Material for a Diaphragm Diamond possesses exceptional physical properties such as high sound velocity and hardness, making it one of the most ideal materials for use in diaphragms. Observations show that even diaphragms made from rigid metals deform in various directions, which causes distortion. However, in the case of diamond, its superior bending rigidity results in extremely minimal displacement. For this product, Final adopted a “Solid Diamond” method. Diamond is crystallized on a silicon base, and then the silicon is dissolved away, leaving behind a diamond foil used in the diaphragm. New Surround Edge Diamond has a specific gravity of 3.5—about twice that of beryllium—posing a challenge when paired with film-type edges, which tend to collapse under the weight and exhibit rolling motion. Additionally, conventional edge materials are prone to resonances at specific frequencies, which is another unavoidable issue. To address these problems, Final developed a new edge using a special polyurethane material. While traditional polyurethane has the drawback of being prone to degradation, this new material overcomes that weakness. It is lightweight yet offers high elasticity and flexibility, successfully resolving the conflicting demands of ease of movement and suppression of unwanted resonance. Collector's Edition This limited first-edition set features a gold-colored housing presented in a handcrafted paulownia wood box. Included is a Suzugami plate—an artisanal tin sheet meticulously hammered and rolled to achieve a unique, foldable form that mimics origami while retaining the texture of metal. Perfect for displaying your earphones with a touch of Japanese craftsmanship. Only 300 units available worldwide. Diaphragm Molding Technology Instead of using conventional adhesive bonding, they developed a unique molding process that combines vacuum forming and thermal molding with a die to achieve adhesive-free molecular bonding. This original technique fundamentally resolves various issues caused by adhesives which often lead to unit-to-unit performance variations between the diaphragm and the edge. Bobbin-Equipped Voice Coil To ensure smooth piston motion of the diaphragm, which is supported by a highly flexible edge, Final Audio re-engineered the voice coil. This approach not only provides excellent conductivity but also eliminates variations and imbalances in weight caused by differences in adhesive application. Ultra-Low Distortion DU By significantly reducing distortion in the ultra-low frequency range and improving amplitude-frequency response in that region, the reproduction of low frequencies has reached an unprecedented level of accuracy. At the same time, interference with the delicate and radiant mid-to-high frequencies—often caused by low-end energy—has also been reduced. This driver achieves an extraordinary balance: it reproduces massive amounts of musical detail with stunning resolution while delivering a remarkable sense of separation, allowing every frequency range to be distinctly perceived. Since distortion is virtually nonexistent, even the silent passages in music feel deeply immersive, and each note stands out with even greater clarity. Stainless Steel Milled Housing with Côtes de Genève Finish The housing is precisely machined from high-rigidity stainless steel, providing robust support for the driver and suppressing unwanted vibrations to deliver clearer sound definition. The surface features a Côtes de Genève finish—a wave-patterned precision milling technique. Exceptional Comfort In contrast to large, organic shapes that make broad contact with the ear, we pursued a design that limits the contact area to reduce pressure. As a result, the earphones provide a pressure-free fit that adapts well to a wide range of ear shapes. When none of the contact points feel tight or forceful, users will be surprised at how comfortable earphones can be—delivering a fit so natural, it feels as if the product were custom-molded. Compared to the A8000, the housing is also smaller, making it even easier to fit securely and comfortably in the ear. ePTFE Shielded Silver-Coated Cable This cable is a collaborative development with Junkosha, renowned for their work in designing and manufacturing high-speed signal transmission cables used in the “Keicomputer." The cable employs silver-coated OFC wire, utilizing the extensive expertise Junkosha has cultivated under its Junflon® brand. For insulation, it features ePTFE (expanded polytetrafluoroethylene), which offers an even lower dielectric constant than traditional PFA (fluoropolymer), ensuring superior signal integrity. Note: Due to its tight fit, Final does not recommend frequent cable swapping or connector detachment except in cases of failure or necessary replacement. Two Types of Eartips Fusion-G A triple-hybrid structure combining three materials—ultra-dense foam, soft silicone, and high-resilience silicone—achieves both excellent sound isolation and pressure-free comfort. Type E Made of two types of silicone with different hardness levels: one for the sound conduit and one for the surface that contacts the ear. The sound conduit is made of firmer silicone with precision grooves to balance strength and flexibility, while the portion that touches the ear uses softer silicone for a comfortable fit and high noise isolation.
