D7000

Equipped with newly developed "Pina Align Diffuser"
A new flagship headphone with a different approach from the D8000

The D7000 is a product that has been conducting research and development since the initiative of the first flagship headphone D8000 announced in 2017 while exploring the ideal structural design. After the development of a newly designed "Pina Align Diffuser" and a more efficient "AFDS: Air film Dumping System (AFDS)", We are fully commercialized as a new flagship alongside the D8000 and D8000 Pro Edition.

In addition to the sound of the delicate high range of the plane magnetic field type, the dynamic quantity of the dynamic type, and the bass with a sense of openness, the resolution is particularly high in the voice and string bands, realizing a glossy smooth sound. 。

In addition, by reviewing the entire design, it succeeded in reducing the weight of about 16 % compared to the D8000 / D8000 Pro Edition. In addition, a special fabric that uses Japanese paper that combines the dry touch and durability on the headband and ear pads is used to achieve high durability.

Equipped with newly developed "Pina Align Diffuser"

The latest acoustic -designed professional recording studio has put into the headphones the concept of acoustic adjustment by diffusion (= diffuse) that is becoming a standard.
There was an idea to install a diffuser in the early stage of the D8000, but it took a long time to develop an appropriate thing under the special conditions of headphones housing. In addition, while measurement under the ideal condition by the measuring instrument, good results were obtained, but when I heard it with the actual ear, the shape of the outer ear (pina) varied, so there was a big difference in sound quality. In order to solve this problem, we repeated simulations and actual hearing experiments according to the shape of various external ears, and finally reached the perfect diffuser shape for every user.

Both the delicate high range of the plane magnetic field type and the dynamic type of dynamic type and the bass with a sense of openness

"Low range with a sense of openness and necessary and sufficient amount"
The conventional plane magnetic field type needs to increase the minimum frequency of the driver unit that can be played by driver units because the diaphragm comes into contact with the magnet in a low range where the amplitude is large. In order to make up for the bass that is insufficient as it is, the inside of the ear pad is sealed and the front of the diaphragm is closed.

This is the same principle that the earphone that is sealed with the earpieces can be played to the low range despite the small size. By sealing the inside of the ear pad, the bass can be played to the low frequency band, but it will be played in a closed space similar to the earphones.

In the D7000, the "AFDS" solves the problem in which the diaphragm contacts the magnet, so that the driver unit can reduce the minimum frequency of the bass that can be played. Along with the breathable ear pads, it enables the reproduction of bass that combines the sense of quantity and openness that could only be realized in an excellent dynamic type.

"Delicate high range"
In order to play a delicate high range, the light weight of the diaphragm is given priority. The D7000 has a lighter weight of about 1/3 of the same diameter dynamic type, and has a very thin aluminum foil coil on the ultra -light film diaphragm. For this reason, it is no longer necessary to use the coils that were essential for the dynamic type and the adhesive to glue the diaphragm, and the problem caused by the adhesive was fundamentally solved, and a delicate high -frequency reproduction was realized.

"Both the delicate high range of a plane magnetic field type and the dynamic quantity of the dynamic type and the bass with a sense of openness"
Due to the delicate high -frequencies of a flat magnetic field type, the dynamic quantity of the dynamic type and the bass with a sense of openness, using the D7000 you will find new discoveries from familiar music, and you will want to re -listen to your favorite music one after another. It is a product that can realize that the excellent sound quality can trigger a deeper music.

Developed more efficient "AFDS: Air film Dumping System"

The conventional plane magnetic field -type driver unit had a problem in which the diaphragm contact the magnet in a low range where the amplitude of the diaphragm increased. In order to solve this, we repeated the simulation of the diaphragm by the finite element method and the measurement with the laser doppler vibration gauge, establishing a new dynamic plate braking technology called "AFDS: Air film Dumping System". This solved the low reproducibility of the bass, which was the weak point of the plane magnetic field type. It is a technique that can be said to be a reconstruction of a plane magnetic field type.

In the D7000, it is possible to reconsider the shape of the coil part and punching metal of the diaphragm, and broke the diaphragm more efficiently according to the physical characteristics of the D7000.

Design to make repair easier in consideration of long -term use

After the purchase, in order to use it for a long time, almost all parts were designed to be disassembled with screws. It enables repair and future upgrades.

Aluminum magnesium alloy cutting housing

To establish AFDS, it requires extremely high accuracy than a general driver unit. Therefore, the cutting housing made of aluminum magnesium alloy is cut at high accuracy.

In -house factory production in pursuit of accuracy

The D series is produced in the headquarters in Kawasaki. The accuracy of the product assembly is greatly affected by the accuracy of the tool, which is a tool that assists assembly, along with the accuracy of the parts. The design and manufacture of production jigs are made in -house so that a small amount of sparse of parts accuracy can be fine -tuned while assembling.

For the D series, we have developed dedicated products, such as vibration plate molding machines and vibration plate tension meters.

To create a really good thing, you need to step into the process of manufacturing parts close to the material. The goodness of MADE IN JAPAN is that the cooperation of a manufacturer close to the material is obtained. The high quality of the product is achieved by consistently controlling from the headwaters of parts to the product to the assembly of products.

Dedicated protection case that can store various cables

The product is stored in a dedicated protection case that is convenient to carry along with accessories. It is possible to lock with the attached dedicated key.

Newly developed and developed ear pads for special fabrics using Japanese paper

Not only the sealed type but also the open headphones, many of them are sealed in the ear pads, extending the characteristic playback frequency to low frequencies where the driver unit cannot be played. However, in order to express the original natural, high -quality low -quality high -quality high -quality expression of the sound source, the driver unit itself has the ability to regenerate to the low frequency, and on top of that, the low -sealing and breathable ear pads. You need to use it. However, many of the conventional flat magnetic field type and general dynamic type are in shortage of low -sealed ear pads.

In the D series, AFDS can extend the low -frequency recycled band, so that the driver unit capabilities alone can play a sufficiently low -frequency playback even with low -sealed ear pads. The earpad, which has a great impact on this sound quality, is a newly developed product for a D -series consisting of a foam with excellent breathability and a special fiber. The D7000 uses a special fabric using Japanese paper that combines dry touch and durability as a surface material. In addition, the headband portion adopts the same material to achieve moisture -resistant and high durability.

Difference in sound quality of D7000/D8000/D8000 Pro Edition

The D7000 is a newly developed "Pina Align Diffuser", and in addition to the sound of both D8000 and D8000 Pro Edition, the sound of the D8000 Pro Edition, especially the sound that has both a sense of openness and the delicate high notes. The feature is that the resolution of the string band is high, and it can be heard slightly closer to the ear.

For the D8000, which was good at listening to "classical music" with a wide dynamic range, D8000 Pro Edition has a more resolution sound quality when listening to "Pops" and "Lock" with narrow dynamic range. I am. On the other hand, "D7000" is an image that is just in the middle.

* This graph does not show the sound quality of the earphones and headphones itself, but the music recording tendency is classified by two characteristics (horizontal axis and vertical axis), and that is compatible with that trend.・ It shows the image of the headphones.

The horizontal axis is a characteristic of the distance of the recorded voice and musical instrument sound. Those with a large sense of distance are expressed as "resolution" with a large "sound field feeling" and small sense of distance. The vertical axis is a feature of the recording dynamic range. The dynamic range is the width of the time change in the loudness of the sound.

Therefore, the horizontal axis of this graph indicates that the more you go to the right, the better the sound field is suitable for music recording works, and the more you go to the left, the more resolution is for music recording works. The vertical axis also shows that the higher the go, the larger the width of the dynamic range, the more suitable for music recording works, and the lower the dynamic range, the smaller the range of the dynamic range is suitable for music recording.
