Package Content

Equipped with a newly designed driver "f-CORE DU". Earphones that can be said to be the new standard in this price range that have achieved overwhelmingly clear sound.

The A4000 started by establishing a new development and production base in order to achieve a level of sound quality that cannot be achieved at this price. We have newly designed a 6mmΦ dynamic driver, including not only parts but also production equipment. The sound quality is designed based on final's original evaluation method established during the development of the flagship earphone A8000. A wide range of music has realized the impression of "transparent sound", which is a sound that can be heard clearly even if it is localized at a distance.

Features

Achievements of new sound quality evaluation method

The development of the A series began with the establishment of a new evaluation method by analyzing the relationship between sound quality and physical characteristics, and the result was the A8000. The A4000 has further evolved that evaluation method. We listen to music recorded in different qualities at different volumes. However, in the conventional evaluation method, it is common to perform subjective evaluation under the condition that the sound pressure that presents the sound is fixed, and it is difficult to judge a good sound that matches the actual product audition. Therefore, as a result of a new research targeting an evaluation method that matches the actual music listening situation, we believe that we were able to produce a product that can be said to be the definitive edition in this price range.

Equipped with a completely newly designed driver unit "f-Core DU" that has reviewed all of the design, parts, and production technology

In order to realize high sound quality that cannot be achieved in this price range, we have set up a new base overseas and newly designed driver parts such as diaphragms, voice coils, magnets, magnetic circuits, adhesives for each part, and even production equipment, and completely renewed. We have developed the designed 6mmφ dynamic driver unit "f-Core DU". 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 an ultra-fine CCAW of 30μ, and the moving parts are thoroughly reduced in weight by assembling with the minimum amount of adhesive. Furthermore, the diaphragm is carefully pressed in a small lot of about 1/3 of the normal size to minimize pressure bias and realize uniform diaphragm molding without distortion.

A feeling of wearing as if customized

The A4000 is based on the housing design, which is the optimum solution of IEM established in the development of the B series, and realizes a better fit. Whether or not the earphones are comfortable to wear depends on the feeling of oppression. At first glance, the method of holding with the repulsive force of silicon, such as ergonomically selecting an organic shape, seems to be correct, but it always puts force on the ear, which puts a strain on the ear without noticing it, and fatigue accumulates. To do. Compared to the shape that is organic and comes into contact with the ear on a large surface, the shape that limits the contact area aims for a comfortable fit without feeling oppressive. The A4000 housing can be held at three points for a stable fit. There will be a total of 3 points: 1 point for the pink part (ear pocket), 1 point for the green part (earpiece), and 1 point for the blue part (tragus) in the figure below. Therefore, it fits many ears. If there is no oppressive feeling at all points of contact, you can feel that wearing earphones is so comfortable, and it is an excellent wearing feeling as if it were a customized earphone.

2Pin connector + original OFC cable

The 2Pin connector is a highly accurate self-developed product. Uses the φ0.78 standard, which is said to be the most versatile. With a soft and supple covering material in consideration of touch noise, it bends flexibly even when using ear hooks, achieving good mounting.

Ear hook to eliminate cable touch noise (with lock mechanism)

Ear hooks are useful for reducing touch noise, and when worn, the unpleasant rumbling noise (cable touch noise) generated by the contact between the cable and the body while walking is dramatically reduced. Our traditional earhooks are slimmer than regular earhooks, have less foreign body sensation than cables with wire or resin, and feature the comfort of forgetting to hang them. A type with a lock mechanism (B type) that can be firmly fixed to the cable.

Original earpieces with different colors on the left and right axes

Two types of silicon materials with different hardness are used for the sound conduit part and the part that touches the ear.
The sound conduit part is made of silicon, which has a higher hardness than the part that touches the ear, and is grooved to achieve both strength and flexibility.
Silicone with low hardness is used for the part that comes into contact with the ear, achieving a comfortable fit and high sound insulation.
By setting the shaft color to gray on one side and red on the other side, you can easily distinguish left and right even in a dim place by turning the earpiece a little and checking the shaft color of the earpiece. In addition, the axis colors of the adjacent sizes are different (the gray axis alternates between dark gray and light gray, and the red axis alternates between red and pink), making it easier to determine the size.
There are 5 sizes, SS / S / M / L / LL, and a case that is convenient to carry is also included.

aging

Aging is a phenomenon in which the sound changes after being used for a certain period of time. Inside the earphone, there is a driver unit that can be said to be a small speaker, and an extremely thin film diaphragm is attached with a coil and adhesive. As the audio signal flows through the coil, the coil moves, and at the same time, the diaphragm moves in micron units to produce sound.
At that time, we cannot make a definite decision, but we think that the adhesive part may affect the slight movement of the diaphragm. By using it for a certain period of time, the diaphragm becomes easier to move, and it seems that the sound quality approaches the original design intention. Since this product has a small diameter, it takes a long time before the change in aging becomes difficult to understand. If you continue to use it normally for about 150 to 200 hours, you should feel that the delicacy has increased. You will get better results if you proceed with aging with the music and volume you normally listen to, rather than aging at high volume or due to noise. It's not an exact metaphor, but if you try to get your shoes in, you'll get wrinkles that aren't what you normally walk. It is better to think that it is more natural to get used to the diaphragm in the environment in which it is used, rather than to make it move unreasonably.

Aging also has a psychoacoustic side. Immediately after purchasing a new earphone, the impression you listened to is not always absolute. In fact, I have made a relative comparison with the earphones I use on a daily basis. If you purchase a new earphone and continue to use it for a certain period of time, that earphone will become the standard. It is easier to select a product that you will not get tired of in the long run if you continue to use it until it becomes the standard and then evaluate the sound quality.
