Final Audio’s signature style

The headphones are crafted using premium materials, making them not just technically advanced devices, but also works of art. The housing is made of durable aviation-grade aluminum or brass, giving the product a unique appearance. The design of the headphones follows Final Audio’s signature style – minimalist, ergonomic, and functional, ensuring comfortable wear even over extended periods.

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 crystallised 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 are available worldwide.

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-moulded. 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, utilising 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

“Suzugami Plate” is also ideal as a display tool

“Suzugami” is made by hammering and rolling tin sheets into thin sheets, and can be easily folded by hand, just like origami. With its stylish appearance, it can also be used as a container for earphones, adding a touch of elegance to any room. This is an original version featuring the final logo.

*Tin gradually changes colour over time. Enjoy the changes in the material itself.

Replaceable dust filters

The dust filter opening may become dirty due to earwax and other substances. The A10000 Collector’s Edition comes with a dust filter that can be replaced by the customer.

*The product is shipped with the dust filter already installed, so there is no need for the customer to install it separately when opening a new product. If the dust filter becomes dirty after using it for a while, please replace it with the included dust filter yourself. Please refer to the instruction manual for replacement instructions.

Package includes:

Carry case, tinplate, earpieces (FUSION-G 5 sizes, TYPE E 5 sizes), earpiece case, MMCX ASSIST, maintenance tool, dust filter, silicone sheet, housing protection tape, auxiliary plate.
