Final Audio A8000 Pure Beryllium Dynamic Driver In-Ear Headphones (Open box)

A8000

final’s flagship model realizes transparent sound for the uplift that can be gained by listening to music

This time, with the aim of achieving transparent sound for earphones, final has developed its own proprietary Perceptual Transparency Measurement (PTM) evaluation methodology. As a result, an ideal diaphragm material that is extremely light and possessing high sound speed comprised of ultra-thin Beryllium foil (Truly Pure Beryllium Diaphragm) has been adopted for the A8000.

Adoption of Truly Pure Beryllium Diaphragm

This time, with the aim of achieving transparent sound for earphones, final has developed its own proprietary Perceptual Transparency Measurement (PTM) evaluation methodology. As a result, an ideal diaphragm material that is extremely light and possessing high sound speed comprised of ultra-thin Beryllium foil (Truly Pure Beryllium Diaphragm) has been adopted for the A8000.

Balancing getting an uplift from a wide range of musical genres with universally good sound.

The superior time response of the A8000 imparts it with sound quality that is capable of providing an uplift from a wide range of music that approaches the extent of the D Series, from the clarity of pop and rock music with a narrow dynamic range all the way to the spatial impression of classical and jazz music with a wide dynamic range. The most distinct characteristic of the A8000 is that it realizes such sound quality not by its ability to create sound capable of attracting a small number of wild fans through its strong individuality, but rather sound aimed at greater universality.

The Feeling of a Customized Fit

Based on the IEM chassis design developed for the B series that has become established as an ideal solution, the A8000 realizes a superior sense of fit. Whether or not the fit of earphones feels superior is determined by the sense of oppression. While at first glance it may seem correct to select an ergonomically praised organic shape to be held in place by the elasticity of silicon, this places ordinary pressure on the ear that serves as an unwary burden and leads to accumulation of fatigue. In limiting the area of contact in comparison to an organically shaped surface that comes in contact with a large area of the ear, this product aims for a sense of fit with no feeling of oppression. For that reason, it is suitable for the ears of many different people. If there is no feeling of oppression at any of the points of contact, that makes for such a comfortable, superior feeling of a customized earphone fit.

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

For the A8000, in order to optimize operation of the driver, the inside of the driver unit chassis is divided into four chambers (Tetra-Chamber Construction); the driver ante-chamber and the double construction driver post-chamber and the MMCX connector portion are separated into different chasses. The driver is direct mounted into the ante-chamber of the chassis by a design that suppresses unnecessary vibration to achieve a distinct sound contour. Additionally, the use of four chambers achieves a balance between volume and tightness in the low-range while at the same time preventing leakage of sound.

MMCX Connector & Original high purity OFC silver coated cable

The MMCX connector was developed in-company. We've used high-purity OFC silver coated cables that provide a wide sound stage. The outer tube is made from PVC for maximum flexibility. The user will experience surprising flexibility that both makes the cable extremely easy to use as well as reducing the likelihood of microphonics. In addition, the MMCX plug and the 3.5 mm mini-plug have a tendency to disconnect so we've far exceeded the regular QA pass criteria of a 5,000-time bend test by changing the connection design to one that can withstand more than 50,000 bends.

MMCX ASSIST for easy plug removal

An item for the smooth insertion and removal of earphone cables using an MMCX connector.

Using MMCX ASSIST the plug can be removed with surprising ease by applying proper force to the MMCX connector in the direction for cable removal.

It also prevents the contingency of the cable from becoming severed by mistakenly pulling on the cable portion of the MMCX connector plug.

Ear hooks that alleviate cable touch noise (Incorporates lock mechanism)

An ear hook is effective in reducing touch noise; wearing it when walking dramatically reduces the unpleasant rustling sound that may occur when the cable rubs against the body (cable touch noise). In the past, our company’s ear hooks have characteristically been slimmer than ordinary and virtually indistinguishable from a wire or rosin filled cable, making it so comfortable that it is easy to forget that one is even wearing it. This time we have newly added a cable lock mechanism.

Original earpieces with a color difference between the left and right bushes.

Two types of silicon differing in rigidity are employed for the sound conduit and for the earbud that comes into contact with the user’s ear. The silicon used for the sound conduit is more rigid than that used for the earbud, and by having groove processing applied to it, combines both strength and flexibility. Soft silicon has been employed for the earbud, making for a comfortable fit and a high level of sound insulation.
One of the bushes is gray, while the other is red; by pulling the earpiece back slightly to check the color of the bush, it is easy to distinguish between left and right, even in places with subdued lighting. Since the bush colors of neighboring sizes are different (the gray bushes alternate between dark and light gray; the red bushes alternate between red and pink), it is also easy to distinguish between sizes.

Comes in 5 sizes – SS/S/M/L/LL

Interchangeable dust filter

The open portion of the dust filter may become soiled with earwax, etc. For the A8000, we have shaped the dust filter in such a manner that it can be removed and replaced by the customer, and a replacement dust filter is included as an accessory.

Aluminum & Silicone hybrid carry case

The aluminum carry case has been designed to strike a balance between fitting in your pocket and protecting the A8000. Cut aluminum is used for portions to which force is applied. The interior is a soft silicone dome to prevent scratching. Attention to detail is evident by other labor, such as inclusion of an internal partition to prevent the chassis from getting scratched by moving back and forth.

How to wear the earphones

This product is an earphone that is hung over the ear. The transmission of touch noise to the ear can be prevented by placing the cable on the ear to achieve a comfortable fit.

STEP1 Confirm the R and L marks on the inside of the chassis. R is right, and L is left.

STEP2 Run the cable toward the front from behind the ear, and insert the earpiece of the earphone into the ear.

STEP3 If it is difficult to fir the earphone into the cavity of concha, try to insert the earphone while pulling back and somewhat upward on the ear lobe.

* If the cable does not fit on the back of the ear, please use the ear hook accessory.
* If the fit is too loose, try changing the size of the sleeve. In some cases, the size of the left and right earpieces may be different.

Aging

Aging is a phenomenon by which sound changes by continued use over a certain period of time. A driver unit produces sound through the vibration of an extremely thin heat-formed film. The cause is not clear, but it is thought that the film might become accustomed to the stress applied from the forming of the film or stress from the adhesive through continued use over time so that minute signals can be transmitted easily. A long period of time is required before the aging effects on this product become unnoticeable. Generally, through 150 to 200 hours of ordinary use sensitivity increases to achieve the level of sound quality for which the product had been originally designed.

Sound quality reviews

Sound is not muddy at all, extremely high clarity. The vocals and instruments comprising music can each be heard perfectly, and music can be enjoyed with a good feeling. Offers unparalleled reproduction of sound from percussion instruments, piano and other instruments for which good sound build-up is particularly demanded. From classical music to pops, rhythm can be vibrantly delineated. Furthermore, each sound is localized as a silhouette floating in space, as a preface to that, every nuance of vocals is perfectly reproduced, therefore new inspiration can be attained from familiar tracks of music to which one has already become accustomed.
