Limited color and package of only 300 units worldwide

As the first limited package, the body color is gold and comes with a special collector's edition box. Additionally, it includes a "Suzugami plate" made by hammering and thinly rolling tin, which can be easily bent by hand like origami while retaining a metallic feel. Please use it as a display tool for earphones. Only 300 units are produced worldwide.

*There are two types of Suzugami, but you cannot specify the type

Development of ultra-low distortion DU equipped with Tulu diamond diaphragm


Diamond, in terms of properties, excels in sound velocity and hardness, making it the most suitable material for a diaphragm. Its exceptional flexural rigidity greatly contributed to the realization of the “ultra-low distortion DU” targeted this time. Observing with a laser displacement meter, even hard metal diaphragms deform in various directions, causing distortion, but in the case of diamond, its flexural rigidity results in extremely small displacement, suppressing noise generated on the diaphragm surface. Its exceptional flexural rigidity greatly contributed to the realization of the ultra-low distortion DU targeted this time. In this product, after crystallizing diamond on silicon, the method of dissolving silicon is adopted to manufacture the diamond diaphragm, known as "Tulu diamond."

Diamond has a specific gravity of 3.5g/cm³, about twice that of beryllium, posing a problem of rolling due to the weight in film-based edges. Additionally, general edge materials cannot avoid the problem of resonance occurring at specific frequencies. To solve these, a special polyurethane was adopted. Traditional polyurethanes had the drawback of being prone to degradation, but this material overcomes that weakness. It combines light weight with high elasticity and extensibility, addressing the conflicting issues of ease of movement and prevention of unwanted resonance.

Developed a unique special forming technology that combines vacuum forming and thermal forming with molds, without using adhesives for bonding, fundamentally solving various problems such as individual differences due to coating amount of adhesives that arise between diaphragms and edges.



To guide the diaphragm supported by a highly flexible edge to a smooth piston motion, the design of a voice coil, usually fixed with adhesive, was revised, and a bobbin-attached coil was adopted. This achieves high conductivity and prevents weight imbalance and bias due to the coating amount of adhesives.

Through the development of the materials and manufacturing technology of the aforementioned diaphragm, the newly developed DU equipped with a diamond diaphragm has achieved an astonishing distortion rate of less than 1/100 compared to conventional models in the range below 100Hz.

The reproduction capability in the low range has improved to an unprecedented level, reducing the impact on the vibrant and delicate mid-high range. While reproducing vast musical information with overwhelming resolution, it achieves a surprising sense of separation that can be felt regardless of the focus range. Additionally, as no distortion is felt, the silence of the music's silent parts is vividly perceived, and each sound is heard more distinctly.


Stainless steel case with Côtes de Genève finish

The case uses a precisely cut stainless steel case with high rigidity. It strongly supports the driver, and by suppressing unnecessary vibrations, the sound stage becomes clear. Furthermore, the case is finished with a precise Côtes de Genève wave pattern cut. Not only an aesthetic element, but as the cut surface directly contributes to the finish, it has little precision deviation and is a refined technology often used in the internal components of high-end watches.

Design for easy repair considering long-term use

Instead of using adhesives for assembling the case and attaching the DU, a high-difficulty screw lock design is adopted, allowing for long-term repair. Additionally, each component is strongly supported by the tightening force of the screws, suppressing unnecessary resonance.

Superior Fit with Minimal Contact Surface

Whether the fit of headphones is superior or not is determined by the sense of pressure. While methods such as selecting ergonomically beneficial shapes or maintaining them with the resilience of silicone may seem correct at first glance, they can constantly put pressure on the ears, leading to unnoticed ear strain and accumulated fatigue. Compared to a shape that covers the ears with a large advantageous surface, aiming for a fit without a sense of pressure by limiting the contact surface area was targeted. As a result, it suits the ears of many people. If there is no pressure at all contact points, you will feel that the fit of these headphones is so comfortable, as if they are customized headphones. Additionally, the housing size is smaller compared to the A8000, making them easier to fit into the ears.


High-Precision In-House MMCX Connector with ePTFE Silver Coated Cable

Jointly developed with Furukawa Electric, renowned for developing and manufacturing cables that pursue signal transmission speed for supercomputers like "Kyo". For the wire material, we used OFC wire with a silver coating that Furukawa Electric has cultivated over many years as a brand, and for the insulation membrane, ePTFE (expanded polytetrafluoroethylene™) boasting an even lower dielectric constant than the conventional PFA (fluoropolymer) was used. Everything is specially designed for the A10000.

The MMCX connector has been redesigned for higher precision to enhance the reliability of our conventionally developed products. The 2PIN relies on the pin's own spring force for retention, making it structurally less durable, so MMCX is adopted for long-term reliability.

※The MMCX connector of this model is specially designed to be difficult to insert and remove for high-precision products. We do not recommend replacing or removing the cable and terminals for purposes other than malfunction.

Two Types of Eartips: "FUSION-G" and "TYPE E"

This product includes two types of eartips, "FUSION-G" and "TYPE E", each in five sizes: SS/S/M/L/LL.


A triple hybrid structure combining three materials: super-dense foam × soft silicone × high-elastic silicone, achieving both high sound insulation and a comfortable fit without pressure. The "super-dense foam" is designed thinly, allowing it to be worn without crushing it with fingers. This reduces pressure and achieves high sound insulation. Furthermore, since it adopts the same shape as the silicone type, the tendency of sound quality to change is minimized, bringing out the original sound quality of the headphones in use.


Adopting two types of silicone materials with different hardness for the sound conduit part and the part touching the ear. The sound conduit part is processed with grooves on silicone harder than the part touching the ear, balancing strength and flexibility. For the part touching the ear, soft silicone is used to achieve a comfortable fit and high sound insulation. By coloring one side gray and the other red, it's easier to distinguish left and right even in dim places by slightly twisting the eartips and checking the axis color.

Interchangeable Dust Filter

The dust filter part may get dirty depending on the ear canal, etc. In the A10000 Collector's Edition, the dust filter is designed to be interchangeable by the customer, and a dust filter is included.

※The product is shipped with the dust filter already installed, so there is no need for the customer to install it separately upon opening a new product. After using it for a while, if the dust filter gets dirty, please replace it with the included dust filter yourself. Please refer to the instruction manual for the replacement method.
