The A5000 features the "f-Core DU" driver, which is entirely developed and designed in-house, including not only the components but also the production equipment. The sound quality was designed based on final's unique evaluation method established during the development of the flagship A8000 earphones. In addition to the impression of a "transparent sound," where sounds positioned at a distance are clearly audible, even the finest sounds in the mid-low frequencies can be heard, giving a sense of depth to each and every note. Furthermore, it comes standard with a newly designed 2-pin soft silver-coated cable developed specifically for the A5000. The braided cable is easy to handle, allowing you to experience the A5000's sound with even greater clarity.
The results of a new sound quality evaluation method: The development of the A-series began with establishing a new evaluation method based on an analysis of the relationship between sound quality and physical characteristics, and the results have culminated in the A8000. We listen to music recorded at various quality levels and at various volumes. However, conventional evaluation methods generally involve subjective evaluation under fixed conditions such as sound pressure, making it difficult to judge good sound in a way that reflects actual product listening. The A5000 employs a new evaluation method for sound creation that is in line with actual music listening conditions.
Equipped with the completely redesigned "f-Core DU" driver unit, which re-examines everything from design, components, and production technology. In order to achieve a high level of sound quality that is unheard of in this price range, we established a new base overseas and developed the completely redesigned 6mmφ dynamic driver unit "f-Core DU", redesigning driver components such as the diaphragm, voice coil, magnet, magnetic circuit, and adhesives for each part, as well as production equipment. The material used for the driver front housing is brass, which is less affected by magnetic force than ordinary aluminum and has a higher specific gravity. In order to improve the time response performance of the diaphragm, the voice coil uses ultra-fine 30μ CCAW and the movable parts are thoroughly lightened by assembling with a minimum amount of adhesive. Furthermore, the diaphragm is carefully pressed in small batches of about 1/3 the usual amount, minimizing pressure unevenness and achieving the formation of a uniform diaphragm without distortion.
A Custom-Like Fit The A5000 builds upon the optimal housing design established in the B series for IEMs, achieving an even better fit. Whether earphones fit well or not is determined by the amount of pressure they cause. While methods that rely on the resilience of silicone, such as those that claim to be ergonomic and use organic shapes, may seem correct at first glance, they constantly apply pressure to the ear, unknowingly putting strain on the ear and accumulating fatigue. Compared to organic shapes that make contact with the ear over a large surface area, we aimed for a pressure-free fit by limiting the contact area. The A5000 housing provides a stable fit by being held at three points. These are one point in the pink area (ear pocket) in the diagram below, one point in the green area (eartip), and one point in the blue area (tragus), for a total of three points. Therefore, it fits most people's ears. You will feel that earphones can be this comfortable if there is no pressure at any of the contact points, resulting in an excellent fit that feels like custom-made earphones.
Newly designed 2-pin soft silver-coated cable. The included cable is a newly designed product developed specifically for the A5000. It features 8 braided silver-coated OFC wires, making it soft and easy to handle. The 2-pin connector is a high-precision, in-house developed product, adopting the φ0.78 standard, which is considered to be the most versatile.
Ear hooks with locking mechanism to eliminate cable touch noise. Ear hooks are effective in reducing touch noise, and when worn, they dramatically reduce the unpleasant rustling sound (cable touch noise) caused by the cable touching your body while walking. Our conventional ear hooks are slimmer than typical ear hooks, and unlike cables containing wires or resin, they feel less like a foreign object, offering a level of comfort that makes you forget you're wearing them. This is a type (TYPE B) with a locking mechanism that securely fastens to the cable.
These ear tips offer the ultimate in comfort. They utilize two types of silicone material with different hardness levels for the sound conduit and the part that touches the ear. The sound conduit uses a harder silicone material with grooves to achieve both strength and flexibility. The part that touches the ear uses soft silicone, resulting in a comfortable fit and high sound isolation. By using gray for one stem and red for the other, you can easily distinguish between left and right even in dimly lit places by slightly lifting the ear tip to check the stem color. Furthermore, the stem colors of adjacent sizes are different (gray stems alternate between dark and light gray, red stems alternate between red and pink), making it easier to distinguish between sizes. Five sizes, SS/S/M/L/LL, are included. Choose the size that suits you best.
This silicone carrying case allows you to easily store your earphones by rolling up the cable. The earphones themselves are softly secured by a thin, dome-shaped silicone lid.
Featuring our proprietary "f-CORE DU" driver, these headphones deliver crystal-clear sound with a sense of depth, resulting in a truly transparent audio experience.
