Limited color and package of only 300 units worldwide

As a first-time limited package, we have prepared a collector's edition with a gold color body and a special paulownia wood box. Also included is a ``Suzugami Plate,'' which is made by pounding and rolling a tin plate into a thin layer. Although it has a metal texture, it can be easily folded by hand, just like origami. Please use it as a display tool for your earphones. Production is limited to 300 units worldwide.

*There are two types of Suzugami patterns, but it is not possible to specify the pattern.

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


Diamond has excellent physical properties such as speed of sound and hardness, making it the most suitable material for diaphragms. In particular, its excellent bending rigidity greatly contributed to the realization of the "ultra-low distortion DU" that we were aiming for. When observed with a laser displacement meter, even a hard metal diaphragm deforms in various directions, causing distortion, but in the case of diamond, its bending rigidity means that the displacement is extremely small, suppressing the noise generated on the diaphragm surface. In particular, its excellent bending rigidity greatly contributed to the realization of the ultra-low distortion DU that we were aiming for. This product uses ``True Diamond'', which manufactures diamond foil by crystallizing diamond on silicon and then melting the silicon.

Diamond has a specific gravity of 3.5g/cm³, which is about twice that of beryllium, and there was a problem with film-based edges that would lose weight and roll. Additionally, common edge materials inevitably suffer from the problem of resonance at certain frequencies. To solve these problems, we adopted a special polyurethane. Conventional polyurethane had the disadvantage of being easily degraded, but this material overcomes that weakness. It is lightweight and has high elasticity and stretchability, solving the contradictory problems of ease of movement and preventing unnecessary resonance.

Rather than bonding with common adhesives, we have developed a unique special molding technology that combines pressure molding and thermoforming using a mold to create intermolecular bonds without using adhesives. This fundamentally solves various problems caused by the adhesive between the diaphragm and the edge, such as individual differences due to differences in the amount of application.



In order to guide the diaphragm, which is supported by highly flexible edges, to smooth piston motion, we have redesigned the voice coil, which is normally hardened with adhesive, and adopted a coil with a bobbin. This achieves high conductivity and prevents weight variations and imbalances due to the amount of adhesive applied.

Through the development of the above-mentioned diaphragm material and manufacturing technology, the newly developed DU equipped with a diamond diaphragm has achieved an astonishing distortion rate of less than 1/100 of that of the conventional model in the frequency band below 100Hz.

By reducing distortion in the ultra-low range and improving the amplitude-frequency characteristics of the ultra-low range, the reproducibility of the low range has been improved to an extent never experienced before, and the overlap in the delicate and gorgeous mid-high range with good transients has also been reduced. While reproducing a huge amount of music information with overwhelming resolution, it also achieves an amazing sense of separation, allowing you to feel it no matter which band you focus on. In addition, since there is no distortion at all, you can feel the quietness of the silent parts of the song more clearly, and each note can be heard more clearly.


Stainless steel machined housing with Côtes de Genève

The casing is made of highly rigid stainless steel and precisely machined. The design firmly supports the driver and suppresses unnecessary vibrations, making the outline of the sound clearer. In addition, the casing is subjected to a wavy precision cutting process called "Côtes de Genève." It is not only an aesthetic element, but compared to a polished finish, the cut surface remains the same as the finished dimension, so there are fewer errors in accuracy, and it is a sophisticated technology that is often used in the internal parts of luxury watches.

Designed for long-term use and easy repair

Long-term repairs are possible by not using adhesives to assemble the casing or attaching the DU, but by using screws, which are difficult to design. In addition, each component is strongly supported by the tightening force of the screws, suppressing unnecessary resonance.

Excellent wearing comfort with small contact area

The feeling of pressure determines whether the earphones are comfortable to wear or not. At first glance, the method of holding the earpiece using the repulsive force of silicone, such as choosing an ergonomic and organic shape, seems to be the right method, but it constantly puts pressure on the ear, which puts strain on the ear without you noticing, and fatigue accumulates. Compared to the organic, large surface that touches the ear, we aimed for a shape that limits the contact area to create a comfortable fit without any pressure. Therefore, it fits most people's ears. If there was no feeling of pressure at all the points of contact, it would be so comfortable to wear the earphones.It has an excellent fit that makes you feel as if you were wearing customized earphones. Additionally, the housing size is smaller than the A8000, making it easier to fit in your ear.


ePTFE silver-coated cable with high-precision in-house MMCX connectors

A jointly developed product with Junkosha, which is famous for developing and manufacturing cables that pursue the highest signal transmission speeds for the K supercomputer. The wire material is silver-coated OFC wire, which combines the know-how that Junkosha has cultivated over many years under the Junflon brand, and the insulation coating is ePTFE (Expanded Teflon™), which boasts an even lower dielectric constant than conventional PFA (fluoropolymer). All are special specifications designed for A10000.

The MMCX connector has been redesigned to be more reliable and more accurate than the conventional in-house developed product. 2PIN relies on the springiness of the pin itself for its removal force, making it difficult to provide structural durability, so MMCX is used for long-term reliability.

*The MMCX connector of this model is a high-precision product, so it is designed to be particularly difficult to insert and remove. We do not recommend re-cabling or inserting or removing terminals for purposes other than replacement due to failure.

Includes two types of earpieces: “FUSION-G” and “TYPE E”

This product comes with two types of earpieces, ``FUSION-G'' and ``TYPE E,'' each in 5 sizes: SS/S/M/L/LL.


The triple hybrid structure combines three materials: ultra-density foam, soft silicone, and high-elastic silicone to achieve both high sound insulation and a comfortable fit without feeling pressured.
The "super-density foam" has a thin design and can be installed without crushing it with your fingers. This reduces the feeling of pressure and achieves high sound insulation. In addition, since they use the same shape as the silicone type, there is less chance of changing the sound quality, bringing out the original sound quality of the earphones you are using.


Adopts two types of silicone materials with different hardness for the sound conduit part and the part that touches the ear. The sound conduit part is made of silicone, which is harder than the part that touches the ear, and is grooved to achieve both strength and flexibility.
The parts that touch the ears are made of soft silicone, providing a comfortable fit and high sound insulation. By making the shaft color gray on one side and red on the other, you can easily tell the left and right sides apart even in dimly lit places by flipping the earpiece slightly and checking the color of the earpiece shaft.

“Suzugami Plate” is also perfect as a display tool.

``Suzugami'' is made by pounding and rolling tin plates into thin sheets that can be easily bent by hand, just like origami. It has a stylish appearance and can be used as a container for earphones to brighten up your room. finalThis is the original version with the logo.

*The color of tin will gradually change over time. Please enjoy the changes in the material itself.
