The flagship of the Final series offers a transparent sound that makes listening to music even more enjoyable.

The development of the A8000 began with the reconstruction of the physical measurement methods and the subjective evaluation methods. With the subjective evaluation method introduced at the time of the development of the D8000, the E series achieved a sound quality that was highly rated by many people and became a best-seller.

With the A8000, a new evaluation index has been integrated into this subjective evaluation method. Among the factors that determine the sound quality of earphones and headphones, the amplitude frequency response is the most important, but there are also sound impressions that cannot be explained by it.

For example, the most critically evaluated aspect of classical music recordings is transparent sound, a sound impression in which the sound is very clear even when localized at a distant location. We consider the realization of this sound impression to be extremely important in order to uplift oneself when listening to music.

We believe that the high rating of our D8000 headphone is due to the realization of such transparent sound. Previously, we used the amplitude frequency response, called tuning, to modify the sound of our headphones, but since the time response cannot be changed significantly, it was difficult to achieve transparent sound through tuning.

With the aim of achieving transparent sound for earphones, final has developed its own proprietary evaluation method for measuring perceived transparency (Perceptual Transparency Measurement, PTM).

As a result of evaluating and improving the relationships between the main components analyzed by the results of subjective evaluation and impulse response data analysis, which could not be derived from the frequency response in the past, an ideal diaphragm material that is extremely light and has a high speed of sound was chosen for the A8000. It consists of an ultra-thin beryllium film (Truly Pure Beryllium Diaphragm).

The A8000 uses a diaphragm made of ultra-thin beryllium foil (Truly Pure Beryllium Diaphragm), which is considered the ideal diaphragm material due to its low weight and high speed of sound.

With a specific gravity of 1.85 and a sound propagation speed of 12,900 m/s, surpassed only by diamond, beryllium has ideal properties for a membrane material.

The use of pure beryllium results in an improved timing response that makes the sound highly transparent. The sharpness of the sound structure and the lingering resonance of the sound can be clearly felt, as can the silence between the sounds.

Manufacturing thin pure beryllium foil is difficult. Our engineers had to work hard to make it strong enough for the product, but it can be said that it is a valuable material that rewards our hard work.In order to achieve a transparent sound through such superior materials, the same high demands were placed on the other components of the drive unit as well as on the design and manufacturing technology.

We have succeeded in leveraging the experience gained from developing and manufacturing our own dynamic drive unit to take advantage of the benefits of pure beryllium.

In the past, a beryllium diaphragm was made by depositing a thin layer of beryllium in a vacuum onto a resin film. This was an effective method of improvement, but the properties of the film remain predominant. When pure beryllium is used as the only material for the sound-producing part of the diaphragm, the sound and properties are completely different.

The balancing act between a wide range of music genres and a universally good sound.

The sound design for these models took into account the relationship between the spatial impression and the dynamic range of the music, as well as the physical properties of earphones and headphones. We categorized the sound production in music recordings on these two axes: spatial impression and dynamic range.

One school of thought concerns the perception of distance. It is thought that in classical and jazz recordings, aspects of spatiality such as sense of distance, width and reverberation are more prominent. In rock, pop and many recent animation soundtrack recordings, however, spatiality is not emphasized as much. It is thought that more emphasis is placed on clarity, which brings the various instruments and vocals to the fore.

Another approach is dynamic range, that is, the change in volume over time. If the dynamic range is large, it is of course possible to use the change in volume over time to achieve a more dynamic expression of the music. However, there are some types of music where recordings with a narrower dynamic range are preferable so that the individual instruments and voices appear quite normal before the eyes of the listener.

The difference between these two ways of thinking is not about which is better, but rather about how music is composed and what demands are placed on it. In classical music, especially orchestral music, the spatial orientation of the instruments is particularly important.

String instruments are closest to the audience, wind instruments and percussion behind them. If the balance between the spatial orientation and the volume of the individual instrument groups were to break down, the music would disintegrate.

For this reason, this type of music does not require a uniform clarity of sound that allows each instrument to appear before the listener's eyes. Even in classical music, for example, a string quartet would have a narrow dynamic range and the clarity of each instrument would be more prominent.

In rock and pop music, on the other hand, spatiality is not as important as in classical music, and more emphasis is placed on clarity than on spatiality.

These requirements are very important, especially for listening with headphones and earphones, and it has been shown that implementing appropriate target curves and driver designs leads to a deeper musical enjoyment.

In the graph below, the spatiality and clarity of the music are plotted on the x-axis and the dynamic range on the y-axis.

The A8000's superior timing gives it a sound quality capable of reproducing a wide range of music approaching the scope of the D Series with a clarity that extends from pop and rock music with a narrow dynamic range to the spatial impression of classical and jazz music with a wide dynamic range.

The peculiarity of the A8000 is that it achieves such sound quality not by producing a sound that attracts a small number of fans through its strong individuality, but a sound that aims at greater universality.

The feeling of a tailor-made fit

Based on the IEM housing design developed for the B series, which has been established as the ideal solution, the A8000 offers an excellent fit feeling. Whether the fit of a headphone is superior or not is determined by the feeling of oppression.

At first glance, it may seem right to choose an ergonomically praised organic shape that is held in place by the elasticity of the silicone, but this puts a normal pressure on the ear that acts as an unwanted strain and leads to fatigue.

By limiting the contact area compared to an organically shaped surface that comes into contact with a large area of ​​the ear, this product aims to provide a feeling of fit without a feeling of oppression. For this reason, it is suitable for the ears of many different people. Having no feeling of oppression at any of the contact points provides a comfortable, superior feeling of a tailored earphone fit.

Precisely ground stainless steel chassis with "Tetra-Chamber Construction"

The volume and shape of the chambers in front of and behind the dynamic drive unit have a major influence on the sound quality. In particular, the operation of the newly developed True Beryllium driver is extremely sensitive and is strongly influenced by the spaces in the chassis.

The internal design of the chassis can be calculated to some extent through simulations, but after that repeated tests must be carried out with a real product until the sound quality goals are achieved.

To optimize the operation of the driver, the interior of the A8000 chassis is divided into four chambers (tetra-chamber construction); the driver pre-chamber and the driver post-chamber in dual design, as well as the MMCX connection area are divided into different chambers.

The driver is built directly into the pre-chamber of the chassis, which suppresses unnecessary vibrations and achieves a clear sound contour. In addition, the use of four chambers achieves a balance between volume and tightness in the low frequency range, while at the same time preventing sound loss.

MMCX connector & Original high-purity OFC silver coated cable

The MMCX connector was developed in our company. We used high-purity OFC silver-coated cables that provide a wide sound stage. These jointly developed cables were originally developed by and are currently manufactured by the renowned Junkosha Corporation for the supercomputer “Kei” because they have a high signal transmission speed.

The insulation film is made of PFA, also developed by Junkosha, who used their extensive know-how through the JUNFLON® brand to create the ultimate low-pollutant material. The outer tube is made of PVC for maximum flexibility.

The user will experience a surprising flexibility that both makes the cable extremely easy to use and reduces the likelihood of microphonics. In addition, the MMCX connector and the 3.5mm mini-plug are prone to loosening, so we have far exceeded the regular quality assurance criteria of a 5,000-time bend test by modifying the connection design to withstand more than 50,000 bends.

* Junkosha: Japanese company Junkosha designs and manufactures products such as high-speed coaxial cables, which have the world's fastest transmission speed at 95% of the speed of light, as well as cables for demanding areas such as shipping, aerospace, healthcare and power generation plants.

These special cables require a high level of engineering and are based on fluoropolymers. Junkosha's cables are often referred to by the brand name JUNFLON® and have earned the great trust of engineers who require special cables.

MMCX ASSIST for easy removal of the plug

An item for easy plugging and unplugging of headphone cables with MMCX connectors.  With MMCX ASSIST, the connector can be disconnected with surprising ease by applying the right force to the MMCX connector in the direction you want the cable to be disconnected.  It also prevents the cable from being severed by accidentally pulling on the cable part of the MMCX connector.

Ear hooks that reduce the noise of the cable (with locking mechanism)

Wearing an ear hook significantly reduces the unpleasant rustling noise that can occur when the cable rubs against your body (cable touch noise). In the past, our company's ear hooks were typically slimmer than usual and virtually indistinguishable from a wire or rosin-filled cable. This time, we added a new cable locking mechanism.

Original ear tips with a color difference between the left and right socket.

Two types of silicone are used for the sound conductor and the earplug that comes into contact with the user's ear, which differ in their firmness. The silicone used for the sound conductor is stiffer than that used for the earplug, and combines both firmness and flexibility through the groove processing. Soft silicone is used for the earplug, which ensures a comfortable fit and high sound insulation.

One of the jacks is gray, the other red; if you pull the earpiece back slightly to check the jack color, you can easily distinguish between left and right, even in places with dim lighting. Since the jack colors of adjacent sizes are different (the gray jacks alternate between dark and light gray; the red jacks alternate between red and pink), it is also easy to distinguish between the sizes.

Available in 5 sizes - SS/S/M/L/LL

Replaceable dust filter

The open part of the dust filter can be contaminated by ear wax, etc. In the A8000, we designed the dust filter so that it can be removed and replaced by the customer, and a replacement dust filter is provided as an accessory.

* The product comes with a dust filter already installed, so the customer does not need to install it by himself after opening the package for a new product. If the dust filter becomes dirty for a long period of time, the customer is requested to replace it using the dust filter accessory provided. Please refer to the instruction manual for the replacement procedure.

aluminum and silicone hybrid carrying case

The aluminum carrying case has been designed to both fit in your pocket and protect the A8000. Cut aluminum is used for parts that will be subject to force, and the interior is made of a soft silicone dome that prevents scratches. The attention to detail is also evident in other details, such as an internal divider that prevents the case from being scratched by moving it back and forth.
