Although more monomers do not necessarily mean better sound, why do most manufacturers who use balanced armature monomers to design headphones use more monomers in high-end headphones? This is also because most of the balanced armature headphones on the market are traced back to the source of Lou's electronics in the United States, and a few are SONION in Denmark. There are very few earphone fields with self-made balanced armature monomer technology and patents.
As far as the balanced armature monomer produced by Lou's company is concerned, although it can make delicate sound, there are several shortcomings in the completeness of sound presentation. First, the response frequency of a single cell is limited, so Lou's single balanced armature earphone generally performs well for mid-frequency vocals, but its ability to extend high and low frequencies is slightly poor; Secondly, the three-dimensional sense of sound is poor, so it can't have a natural level like high-order dynamic circle; Of course, due to the size of the moving iron, low-frequency diving is not ideal.
It is also because the monomer of the building is supplied in mass production, and at most it is only adjusted by the manufacturer, but it has never been heard that the building is specially designed for a certain manufacturer; Therefore, most of the high-order balanced armature earphones are made up of multiple monomers. Two monomers with different response frequencies (now there are also compound dual-full-range monomers) make up for the lack of each other's range, so that the response frequency can be higher in bass expansion, thus obtaining a sense of space and layering that is difficult to express in the original single monomer.
In my impression, apart from Sony, which announced the launch of independent structure balance armature monomer two years ago, the other one is Final Audio Design. However, Sony still used stacking, but in the end, most of the audio design remained single. As I mentioned in an interview with the former president of Final Audio Design, Takai Jinsheng, their single balanced armature technology was acquired, but it was tailored to the needs of Final Audio Design.
Before the * * * * release of LAB I, which used metal 3D printing to manufacture the frame and used composite monomer to produce headphones for the first time, the top balanced armature monomer of the final audio design was this FI-BA-SS. Although it is a balanced armature single earphone, its appearance is somewhat like the design of a dynamic earphone, and even there are several tiny air holes at the end. In the balanced armature earphone, the appearance of FI-BA-SS is somewhat different.
But FI-BA-SS is still a product designed based on Mr. Jin Jing's unique sound theory. Its frame assembly is made of stainless steel, and the wires are fixed. * * * It consists of four parts, and the three parts that make up the main body are quite thick. It is also because Mr. Takai proposed that the sound is good, and the redundant vibration of audio equipment should be suppressed by weight.
Although it is generally believed that the balance armature monomer has little influence on the design of the moving coil structure frame, because the monomer itself contains a vibrating cavity, after all, the balance armature earphone will still vibrate when it makes sound, and it is also because of this reason that heavy metals are used; The pre-assembly is integrated with the conduit, which simplifies the structure and reduces the loose structure caused by too many assemblies.
However, it is really useless if the back opening is an ordinary Lou's monomer design, but don't forget that FI-BA-SS is a monomer designed by Final Audio Design. As can be seen from official website's explanation, this single body has a small hole to make low frequency. The opening at the back is the patented design "BAM (Balanced Air Movement)", which claims that it will not cause sound leakage but can create natural low frequency, that is to say, although it is a balanced armature, it has some characteristics of mobile headphones.
As for the sound? This is a very unique earphone. If you don't say it, you may think it is a high-order micro-motion ring monomer earphone, and the diaphragm is plated with metal moving ring monomer. But wake up, FI-BA-SS is indeed a balanced armature monomer earphone, and it has only one monomer structure, but it has some characteristics of balanced armature monomer and moving coil monomer.
It inherits the advantages of balanced armature, which is generally cold-bottomed, analytical but easy to drive, and also has the low-frequency dive and spatial layering of moving coil monomer. FI-BA-SS is slightly thinner and the sound is quite accurate. The high-frequency extension is not as high as the high-frequency special balancing armature of the building, but it is smooth and harmonious. Perhaps because of the unique opening design of the monomer, the overall timbre has a cold and resolute style with stainless steel frame.
FI-BA-SS doesn't have much sense of volume at low frequencies, but it has better diving ability than many triple-balanced armature headphones. Except for a few headphones with mixed moving coil and balanced armature or Sony's XBA series of high-end headphones, diving on balanced armature headphones is quite rare. However, most mixed-monomer headphones and Sony's XBA headphones have a sense of disharmony, but FI-BA-SS does not have the problem of compound monomer, because it is a simple monomer and does not need to go through.
Intuitively speaking, FI-BA-SS is not so much a balanced armature earphone as a few high-end ear canal earphones with small moving coils, but usually the moving earphones with metal plating materials are quite difficult to drive. After all, the diaphragm is difficult to vibrate. Even if the aperture is not large, FI-BA-SS can easily hit a certain level with handheld devices, which can be said to be headphones without high driving force.
As for the sense of wearing, the FI-BA-SS is still quite heavyweight in such a volume, which is also due to the fact that the whole frame is cut with thick aluminum alloy, but when wearing, the position of the outlet wire can just be stuck in the earlobe groove of the ear, although it may fall off during strenuous exercise, but the general wearing feeling and stability are not bad; But the wires are very thin.
It's just that I don't know how to locate FI-BA-SS. If the price is simply based on sound, FI-BA-SS does exceed the level of 10,000 yuan, but it is also surrounded by strong enemies at this price. For example, AKG K3003, Sennheiser IE800, Shure SE846, Ultrasone IQ and Weston W60, several small earphone manufacturers have launched customized headphones. The author thinks that the value of FI-BA-SS should also be measured by its insistence on the integrated metal cutting structure and the uniqueness of using a single balanced armature monomer to make sound. Maybe we should appreciate its wonderful sound and treat it as a metal work of art. ..
