Final Final A4000 In-ear Monitor Earphone 2Pin FI-A4DPLDN Product Overview
Results of a new sound quality evaluation method
The development of the A series began by establishing a new evaluation method by analyzing the relationship between sound quality and physical characteristics, and the results came to fruition as the A8000. The evaluation method was further evolved in the A4000. We listen to music recorded in various qualities at different volumes. However, in conventional evaluation methods, it is common to perform subjective evaluations under fixed conditions such as sound pressure showing sound, etc., and it was difficult to determine a good sound in line with actual product auditions. Therefore, as a result of applying evaluation methods in line with actual music listening situations as the target of new research, I think we were able to come to fruition into a product that can be said to be the definitive version in this price range.
Equipped with a completely redesigned driver unit “F-core DU” (F-Core DU) that has reviewed all design, parts, and production technology
In order to achieve high sound quality that cannot be achieved in this price range, we have established new bases overseas, redesigned driver parts such as diaphragms, voice coils, magnets, magnetic circuits, and adhesives for various parts, as well as production equipment, and developed a completely redesigned 6mm φdynamic driver unit “F-core DU”. The driver front housing is made of brass, which is less susceptible to magnetic force than general aluminum and has a higher specific gravity. In order to improve the time response performance of the diaphragm, the voice coil uses a 30μ-ultra-fine CCAW, and the moving parts are thoroughly reduced by assembling them with minimal adhesives. Furthermore, by carefully pressing the diaphragm in small batches of about 1/3 of normal, pressure bias was minimized, and uniform diaphragm molding without distortion was achieved.
Comfortable to wear as if it were customized
The A4000 achieves excellent wearing comfort based on a housing design that is considered the optimal solution for IEM, which is considered by Final. Whether or not the earphones are comfortable to wear is determined by the feeling of compression. The method of holding with silicone's repulsive force, such as claiming ergonomics and choosing an organic shape, seems correct at first glance, but force is always applied to the ears, putting a strain on the ears without realizing it, and fatigue accumulates. Compared to the shape where the large surface comes into contact with the ear, we aimed for a comfortable fit without feeling oppressive by limiting the contact area. The housing of the A4000 is held at 3 points for a stable fit. Therefore, it fits most people's ears. If there is no feeling of pressure at all points of contact, you can feel that the earphones are so comfortable to wear, and they have an excellent fit as if they were customized earphones.
2pin connector+original OFC cable
The 2Pin connector is a high-precision in-house developed product. Adopts the φ0.78 standard, which is said to be the most versatile. The covering material is soft and supple in consideration of touch noise, and bends flexibly even when using earhooks, making it easy to wear.
Earhook (with lock mechanism) to eliminate cable touch noise
The earhook is useful for reducing touch noise, and when worn, the uncomfortable rumbling sound (cable touch noise) generated by touching the cable with the body while walking is dramatically reduced. Our conventional earhooks are slimmer than typical earhooks, have no foreign body feel compared to wire or resin cables, and feature the comfort of forgetting you're wearing them. It is a type with a lock mechanism (B type) that can be securely fixed to a cable.
