D7000

Equipped with the newly developed “Pina Align Diffuser,”
this new flagship headphone takes a different approach from the D8000

The D7000 is the product of ongoing research and development since the conception of the first flagship headphones, the D8000, released in 2017, as we sought the ideal structural design. After developing a newly designed “Pina Align Diffuser” and a driver equipped with a more efficient “AFDS: Air Film Damping System (AFDS),” the D7000 is now ready for commercialization as a new flagship model alongside the D8000 and D8000 Pro Edition.

In addition to the delicate high frequencies of a planar magnetic model and the volume and open bass of a dynamic model, the D7000 delivers a lustrous, smooth sound with high resolution, particularly for vocals and strings.

Furthermore, a complete redesign has resulted in a weight reduction of approximately 16% compared to the D8000 and D8000 Pro Edition. Furthermore, the headband and earpads are made of a special fabric made from washi paper, which combines a dry feel with durability, ensuring high durability.

Equipped with the newly developed “Pina Align Diffuser”

We have incorporated into our headphones the concept of acoustic adjustment through diffusion, which is becoming standard in professional recording studios equipped with the latest acoustic designs. The
idea of ​​incorporating a diffuser existed early in the development of the D8000, but it took a long time to develop something appropriate for the special conditions inside the headphone housing. Also, while measurements using measuring equipment under ideal conditions produced good results, when listening with the actual ear, the shape of the outer ear (pinna) differs from person to person, resulting in large differences in sound quality. To solve this problem, we repeatedly conducted simulations and actual listening experiments tailored to various outer ear shapes, and ultimately arrived at a diffuser shape that is optimal for any user.

The planar magnetic model combines the delicate high frequencies with the dynamic model’s volume and open bass.

“Open feeling and sufficient volume in the bass range.”
With conventional planar magnetic models, the diaphragm comes into contact with magnets at low frequencies where amplitude becomes large, so the minimum frequency of the bass tones that the driver unit can reproduce must be raised. To compensate for the lack of bass tones, the ear pads are sealed, creating an enclosed space in front of the diaphragm.

This is the same principle as how earphones with sealed earpieces are able to reproduce low frequencies despite their small size. Sealing the ear pads allows bass to be reproduced down to low frequencies, but the bass is reproduced in a closed space, just like earphones.

With the D7000, “AFDS” has solved the issue of the diaphragm coming into contact with magnets, making it possible to lower the minimum frequency of the bass tones that the driver unit can reproduce. This, combined with breathable ear pads, enables bass reproduction that combines volume and a sense of openness, something previously only possible with superior dynamic models.

“Delicate High Range.”
To reproduce delicate high frequencies, a lightweight diaphragm is the highest priority. The D7000’s diaphragm is approximately one-third lighter than that of dynamic models of the same diameter, and features an extremely thin aluminum foil coil etched onto an ultra-light film diaphragm. This eliminates the need for adhesives, which are essential in dynamic models to bond the coil and diaphragm, fundamentally resolving the problems associated with adhesives and achieving delicate high-frequency reproduction.

“Combining the delicate high frequencies of a planar magnetic model with the volume and open bass of a dynamic model”
By combining the delicate high frequencies of a planar magnetic model with the volume and open bass of a dynamic model, the D7000 allows you to discover new things in familiar music, inspiring you to listen to your favorite songs over and over again. This product allows you to truly experience how superior sound quality can be an opportunity to connect with the deeper aspects of music.

Developed the more efficient “AFDS: Air Film Damping System”

Conventional planar magnetic driver units have an issue where the diaphragm comes into contact with the magnet at low frequencies where the diaphragm amplitude becomes large. To solve this issue, we conducted diaphragm simulations using the finite element method and repeated measurements using a laser Doppler vibrometer, resulting in the development of a new diaphragm damping technology called “AFDS: Air Film Damping System.” This has resolved the poor bass reproduction that was a weakness of planar magnetic models. This technology can be considered a reinvention of planar magnetic models.

For the D7000, we have reconsidered the shape of the diaphragm coil and perforated metal, making it possible to damp the diaphragm more efficiently in line with the physical characteristics targeted by the D7000.

Designed for long-term use and easy repair

To ensure long-term use after purchase, we have designed the product so that almost all parts can be disassembled with screws, allowing for repairs and future upgrades.

Machined aluminum-magnesium alloy housing

Achieving AFDS requires an extremely high level of precision compared to typical driver units, and for that reason the machined aluminum-magnesium alloy housing has been cut with great precision.

Produced in our own factory with a focus on precision

The D Series is produced at our headquarters in Kawasaki. Product assembly precision depends not only on the precision of the components themselves, but also on the precision of the jigs used to support assembly. We design and manufacture our production jigs in-house, allowing us to fine-tune even the slightest variations in component precision during assembly. We

also develop specialized production equipment, such as diaphragm molding machines, and measuring instruments, such as diaphragm tension meters, specifically for the D Series.

To create truly high-quality products, we must delve into the manufacturing process of components that are close to the raw materials. The beauty of “Made in Japan” is that we can obtain cooperation from manufacturers that are close to the raw materials. We achieve high product quality by consistently controlling everything from the source of the raw materials to product assembly.

Includes a dedicated protective case that can store various cables

The product and accessories are stored in a special protective case that is easy to carry and can be locked with the included special key.

Newly developed open-type ear pads made from special fabric using washi paper

Many headphones, not only closed-type but also open-type headphones, characteristically extend the reproduction frequency range to low frequencies that the driver unit cannot normally reproduce by sealing the ear pads. However, to reproduce the natural, spacious, and high-quality low frequencies inherent in the sound source, the driver unit itself must be capable of reproducing low frequencies, and breathable ear pads with a loose seal are required. However, with all conventional planar magnetic headphones and most general dynamic headphones, low frequencies are lacking with ear pads that are not tightly sealed.

With the D Series, AFDS has been able to extend the reproduction range of low frequencies, allowing the driver unit’s capabilities alone to reproduce sufficient low frequencies even with ear pads that are not tightly sealed. The ear pads, which have a significant impact on sound quality, are newly developed for the D Series, made from highly breathable foam and special fibers. The D7000 uses a special fabric for the surface made from Japanese paper, which combines a dry feel with durability. The same material is also used for the headband, achieving high moisture resistance and durability.

Differences in sound quality between the D7000, D8000, and D8000 Pro Edition

By adopting a newly designed driver, including the newly developed “Pina Align Diffuser,” the D7000 not only achieves the volume and open bass tones and delicate treble tones that are the hallmarks of the D8000 and D8000 Pro Edition, but also features high resolution in the frequency ranges of voices and strings in particular, and sounds that are slightly closer to the ears and are extremely smooth.

While the D8000 excels at listening to “classical music” and other music with a wide dynamic range, the D8000 Pro Edition offers sound quality with a greater sense of resolution when listening to “pops” or “rock” with a narrow dynamic range. In contrast, the “D7000” is thought to be positioned exactly in the middle.

*This graph does not show the sound quality tendencies of the earphones or headphones themselves. Rather, it classifies the tendencies of music recordings according to two characteristics (horizontal and vertical axes) and provides an image of which earphones or headphones are compatible with those tendencies.

The horizontal axis represents the sense of distance of the recorded voice or instrument sound. A greater sense of distance is expressed as a greater sense of spaciousness, while a smaller sense of distance is expressed as a greater sense of resolution. The vertical axis represents the dynamic range of the recording. Dynamic range is the range of change in sound volume over time.

Therefore, the graph’s horizontal axis indicates that it is more suitable for music recordings with a greater sense of spaciousness toward the right, and more suitable for music recordings with a greater sense of resolution toward the left. The vertical axis also indicates that it is more suitable for music recordings with a wider dynamic range toward the top, and more suitable for music recordings with a narrower dynamic range toward the bottom.
