Final Audio A5000: Equipped with in-house developed driver “f-CORE DU”
The Final Audio A5000 achieves transparent sound with crystal clear clarity and deep sound an is equipped with the f-Core DU driver, which was developed and designed entirely in-house, including parts and production equipment. The sound quality was designed based on final’s unique evaluation method established during the development of the flagship earphone A8000. In addition to the so-called “transparent sound” that allows you to clearly hear sounds that are localized at a distance, you can hear even the finer sounds in the mid-low range, giving each sound a sense of depth. I can. In addition, a newly designed 2-Pin soft silver-coated cable developed for the A5000 is standard equipment. The braided cable makes it easy to handle, and you can feel the A5000’s sound even more clearly.
Results of a new sound quality evaluation method
The development of the A series started with the establishment of a new evaluation method based on the analysis of the relationship between sound quality and physical characteristics, and the result was the A8000. We listen to music recorded in different qualities and at different volumes. However, in conventional evaluation methods, subjective evaluation is generally performed under fixed conditions such as the sound pressure that presents the sound, making it difficult to judge good sound based on actual product listening. The Final Audio A5000 uses a new evaluation method for sound creation that matches actual music listening situations.
In-house developed Final Audio A5000 driver unit “f-Core DU” installed
From driver parts such as the diaphragm, voice coil, magnet, magnetic circuit, and adhesives to production equipment, we have newly designed the 6mmφ dynamic driver unit “f-Core DU” for the A5000. The material of the driver front housing is brass, which is less affected by magnetic force and has a higher specific gravity than general aluminum. In order to improve the time response performance of the diaphragm, the voice coil uses 30μ ultra-fine CCAW and is assembled with a minimum amount of adhesive to thoroughly reduce the weight of the moving parts. Furthermore, by carefully pressing the diaphragm in a small lot, about 1/3 of the normal amount, we minimized the unevenness of the pressure and realized a uniform diaphragm without distortion.
A feeling of wearing that seemed to be customized
The Final Audio A5000 is based on the optimal housing design for IEMs established in the development of the B series, and achieves an even better fit. Whether or not the earphones are comfortable to wear is determined by the feeling of pressure. At first glance, the method of holding with the repulsive force of silicon, such as selecting an organic shape that promotes ergonomics, seems to be correct, but it always puts pressure on the ears, and before you realize it, it puts a strain on the ears and accumulates fatigue. To do. Compared to the shape that touches the ear with an organic large surface, the shape that limits the contact area aims for a feeling of wearing without feeling oppressive. The A5000 housing is held at three points for a stable fit. There will be 1 point in the pink part (ear pocket), 1 point in the green part (earpiece), and 1 point in the blue part (tragus), for a total of 3 points. Therefore, it fits most people’s ears. If there is no pressure at all points of contact, you will be able to feel that the earphones are so comfortable to wear, as if they were customized earphones.
Newly designed 2-Pin soft silver coated cable
The attached cable is a newly designed product newly developed for the A5000. 8-core silver-coated OFC wire is woven into it, making it soft and easy to handle. The 2-Pin connector is a high-precision product developed in-house and uses the φ0.78 standard, which is considered to be the most versatile.
Ear hooks (with lock mechanism) to eliminate cable touch noise
Ear hooks are useful for reducing touch noise, and when worn, the unpleasant gurgling sound (cable touch noise) that occurs when the cable touches the body while walking is dramatically reduced. Our conventional ear hooks are slimmer than general ear hooks, and feature a comfort that makes you forget you’re wearing them, as they don’t feel like a foreign object compared to cables containing wires or resin. It is a type (TYPE B) with a lock mechanism that can be firmly fixed to the cable.
Earpieces for the ultimate comfort
Two types of silicone materials with different hardness are used for the sound conduit part and the part that touches the ear. For the sound conduit, the silicon, which is harder than the part that touches the ear, is grooved to achieve both strength and flexibility. Soft silicone is used for the part that touches the ear, realizing a comfortable fit and high sound insulation. By making one shaft color gray and the other red, you can easily distinguish between the left and right earbuds even in dimly lit places by flipping over the earbuds and checking the color of the earbuds. In addition, the adjacent sizes have different axis colors (the gray axis alternates between dark gray and light gray, and the red axis alternates between red and pink), making it easy to distinguish sizes. 5 sizes of SS/S/M/L/LL are included. You can choose according to your preference.
silicone carrying case
It is a silicon carry case that can be rolled up and stored easily. The earphone body is softly fixed with a dome-shaped thin silicone lid.
