The new staple for this price range, features a newly designed driver unit [f-Core DU] which realizes astonishingly natural sound
For the A3000 to achieve the impossibly high-quality sound for this price range requires new development and production facility. 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. A3000 delivers astonishingly natural sound with each sound image vividly localizes over the comfortably and spatially spreading low-range sound.
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 analyzing 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. Conventional evaluation methods, however, generally entail a subjective evaluation under the fixed conditions such as constant sound pressure level , and an evaluation method that takes into account the various practical listening conditions that could actually occur when users evaluate the sound of various products of earphones didn’t exist. 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
In order to achieve sound quality impossible at this price range, we newly developed 6mmφ [f-Core DU] dynamic driver unit from the scratch. To realize the brand new driver, we established new production facility overseas and newly 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. As material for the driver front housing, rather than the traditional aluminum, we used brass, 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 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 realize uniform shaped diaphragm with no deformation.
The Feeling of a Customized Fit
Based on the chassis design that serves as an ideal solution for the IEM that become established during development of the B Series, the A3000 realizes a superior sense of fit. Whether or not earphones offer a superior sensation of fit is determined by the sensation of oppression. While at first glance it may seem correct to select an ergonomic shape and hold it in place with the elasticity of silicone, this always places pressure on the ear which creates an unwary burden and leads to the accumulation of fatigue. By limiting the area that comes in contact with the ear in contrast to an ergonomic shape that comes in contact with a large area of the ear, this product aims to achieve a sense of fit with no feeling of oppression. The green section of the diagram below (earpiece) is the 1st position, the blue section (Tragus) is the 2nd position, and the pink colored section (cavity of the concha) is the 3rd position which contribute to the ultimate stability and fitting. For that reason, it is suitable for the ears of many different people. To the extent that 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.
