Final Audio A3000 In-Ear Earphones Final Audio

The new staple for this price range, features a newly designed driver unit [f-Core DU] which realizes astonishingly clear sound
The 6mm diameter dynamic driver requires not just new parts, but a total redesign of everything, including the production machinery. Sound design was conducted based on our proprietary sound evaluation method established during the development of our flagship A8000 model.

Achievements of a new sound quality evaluation method
The development of the A series began with the establishment of a new sound evaluation method by analysing the relationship between sound quality and physical characteristics. The results came to fruition with the A8000, and the sound evaluation method evolved further with the A3000. We listen to music recorded at various qualities at various sound levels. We believe that researching a sound evaluation method that made it possible to arrive at a realistic evaluation, even under various different listening conditions made it possible to bring to fruition a product that can be said to be the new standard for this price range.

Featuring the completely redesigned [f-Core DU] driver unit, which entails new design, parts and production technology
We developed a new 6mmφ [f-Core DU] dynamic driver unit. To realise the brand new driver, we established a new production facility overseas and designed not only parts for the driver unit such as diaphragm, voice coil, magnet, magnetic circuits, adhesives, but also the production machinery used in the manufacturing process.

Brass was used for the driver’s front housing, a material that is both highly resistant to the effects of magnetism and also boasts a high specific gravity. In order to increase the time response characteristic of the diaphragm, the voice coil employs a 30μ ultrathin CCAW, and a minimum amount of adhesive is used for assembly to thoroughly lighten the moving parts. Moreover, the diaphragms are neatly pressed in small lots of roughly 1/3 the normal size in order to constrain pressure deviation to a minimum and realise a uniform shaped diaphragm with no deformation.

2Pin Connector & Original OFC Cable
The 2-Pin connector is a high precision part that was developed in-house. The plug employs the highest versatility φ0.78 standard. The cable employs soft, supple coating material designed with consideration to touch noise and bends flexibly when used in conjunction with an ear hook to achieve a good fit.

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 is the type with an affixed lock (B Type) that is capable of holding the cable firmly in place.

Original earpieces with a color difference between the left and right bushes
Two types of silicone differing in rigidity are employed for the sound conduit and for the earbud that comes into contact with the user’s ear. The silicone 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 silicone has been employed for the earbud, making for a comfortable fit and a high level of sound insulation.

One of the bushes is grey, while the other is red; by pulling the earpiece back slightly to check the colour of the bush, it is easy to distinguish between left and right, even in places with subdued lighting. Since the bush colours of neighbouring sizes are different (the grey bushes alternate between dark and light grey; the red bushes alternate between red and pink), it is also easy to distinguish between sizes.

Silicon carry case
With this silicon carry case, the cables can be rolled up and stored easily. The earphones themselves are gently secured using thin dome-shaped silicon covers.
