Final A3000 IEM Earphones

About the item

The A3000 has started with a new development and production base to achieve the sound quality of this price. A new 6mmφ dynamic driver has been newly designed, including not only parts but also production equipment. The sound quality is designed based on FINAL's unique evaluation method established during the development of A8000, a flagship earphone. It features an overwhelmingly natural sound, where each sound is located in a loose and low range, where each sound is located with an outline.

The results of the new sound quality evaluation method

The development of the A series started by establishing a new evaluation method based on the analysis of the relationship between sound quality and physical characteristics, and the results were fruitful as A8000. The A3000 has evolved the evaluation method further. We listen to music recorded with various quality at a variety of volume. However, in the conventional evaluation method, it was common to perform subjective evaluation under the fixed conditions of the sound pressure presenting sound, and it was difficult to judge a good sound that was in line with the actual product audition. Therefore, as a result of new research on the evaluation method in line with the actual music listening status, we believe that the definitive product in this price range was imposed.

Equipped with a completely new design driver unit "F-Core Du" (Ef Core DU)

In order to achieve high -quality sound quality that is impossible in this price range, a new base will be set overseas, and driver parts such as diaphragm, voice coil, magnet, magnetic circuit, and each part of each part are newly designed, and completely new. The design 6mmφ dynamic driver unit "F-Core Du" has been developed. The material of the driver front housing uses brass that is less likely to be affected by magnetic force and has a higher specific gravity than ordinary aluminum. In order to improve the time response performance of the diaphragm, the voice coil uses a 30μ ultra -fine CCAW, and the movable portion is thoroughly lighter by assembling it with a minimum adhesive. Furthermore, the diaphragm is carefully pressed with a small lot of about 1/3 of normal, minimizing the bias of pressure, and achieving uniform diaphragms without distortion.

Feeling of mounting as if customized

A3000 has a better feeling of wearing based on the case design, which is the best solution of IEM established by the development of B-series. Whether or not the earphone feels good is determined by the pressure. At first glance, the method of retaining the silicon reconciliation, such as claiming an organic shape and choosing an organic shape, looks correct, but always puts the power to the ears, puts a burden on the ears without notice, and accumulates fatigue. I will do it. Compared to the shape that is organic and large on the ear, we aim for a feeling of mounting without a feeling of pressure. By holding the A3000 housing with 3 points, it has a stable feeling of mounting. One of the pink parts (ear pockets) in the figure below, one point of the green part (earpiece), and one blue (ears). Therefore, it complies with many ears. If there is no feeling of oppression in all the points in contact, you can feel that the installation of the earphones is so comfortable, and it has an excellent feeling as if it were a customized earphone.

2pin connector + original OFC black cable

The 2pin connector is a high precision owned product. The φ0.78 standard, which is considered to be the most versatile, is adopted. It is a soft and supple coated material in consideration of touch noise.

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

The ear hook is useful for reducing touch noise, and the unpleasant sound (cable touch noise) generated by touching the cable and body when walking is dramatically reduced. Our conventional ear hooks are more slim than general ear hooks, featuring the comfort of forgetting to hang it, with no foreign body feeling compared to cables with wires and resin. It is a type with a lock mechanism (Type B) that can be firmly fixed to the cable.

Different axis-colored earpieces that make it easier to make left and right discrimination

Two types of silicone materials with different hardness between the sound conductor part and the part that touch the ears are adopted. In the sound conductor, the strength and flexibility are compatible by applying grooves to silicon with higher hardness than the part that touches the ears. The part that touches the ears is made of soft silicon to achieve comfortable wearing comfort and high sound insulation. One of the shaft colors is gray, and the other is red to turn the earpiece slightly to check the shaft color of the earpiece, making it easier to distinguish between the left and right even in the dim places. Furthermore, the axial color of the next size is different (the gray axis is alternate between dark gray and thin gray, red axis is alternate between red and pink), making it easier to determine the size. Included 5 sizes of SS/S/M/L/LL. You can choose according to your preference.

Silicon carry case

It is a silicon carry case that can be easily stored by rolling the cable. The earphone body is fixed to the software with a thin dome -shaped silicon lid.

aging

Aging is a phenomenon in which the sound changes by continuing to use it for a certain time. Inside the earphones, there is a driver unit that can be said to be a small speaker, and a very thin film diaphragm is pasted with coil and adhesive. The coil moves when the audio signal flows to the coil, and the dynamic plate emits a sound by moving in microns. At that time, we cannot determine, but we believe that the adhesive part may have influenced the small movement of the diaphragm. By using it for a certain period of time, it seems that the dynamic plate becomes easier to move, approaching the original sound quality of the design intention. This product is a small diameter, so it takes longer time to make it difficult to understand the change in aging. If you continue to use normal for about 150 to 200 hours, you will feel that the delicateness has increased. Rather than aging or noise at loud, it is more preferable to proceed with aging with the music and volume you usually hear. It's not an accurate metaphor, but if you make an unreasonable movement to get used to shoes, you'll be able to wrinkles different from everyday walking. It would be better to think that it is more natural to be used in an environment where you use it, rather than making the diaphragm as an unreasonable movement. Aging also has acoustic psychological aspects. The impressions I listened to immediately after purchasing a new earphone are not always absolute. In fact, we have a relative comparison with the earphones used on a daily basis. If you buy a new earphone and keep using it for a certain period of time, the earphone will be the standard. Continuing to use the sound quality after continuing to use it until it becomes the standard makes it easier to choose a product that does not get tired for a long time.
