"Dynamic Iron Four Heavenly Kings" refers to the world's top four heavenly kings of dynamic iron headphones. They are UE (Ultimate Ears), Tone Temei (ETY), Weston (Westone), Shure (S.N. Shure).
UE UE (Ultimate Ears): UE full name ULTIMATE EARS, once with another U.S. brand WESTONE (Westone), is to do hearing aids started. Later UE and WESTONE separated, each produced a series of music earbuds. UE900 is UE non-custom music earbuds of the top models, four-unit three-frequency structure, in many moving-iron non-custom earbuds is considered a high-end model (the same grade and WESTONE's W60, SHURE's SE846, SCL5, etc.). UE900 sound, the most important characteristics of the soundstage is wide-open, very good dynamics, high resolution, rich in detail. In short, it is a high-end non-customized earbuds. In the earbuds, more upscale than the UE900 level should be customized earbuds. He is in accordance with the contours of the human ear ear canal customized, although the sound unit and crossover line are the same thing, but the sound will have a non-custom experience can not be felt, but the sound is good, the price is also a lot more expensive, the UE brand launched the top customized earbuds, such as the UE10, UE11, are as high as seven or eight thousand dollars, the highest end of the top customized earbuds UE18 is up to 6 units, the price is up to 10,000 yuan! The top-end customized earbuds, UE18, have 6 units and cost 10,000 yuan. The price of low-end UE5 even reached the level of four or five thousand.
Shure Shure can become the world's leading microphone brand, when attributed to the founder of Shure (S.N. Shure) advocated the "total quality management philosophy and perfect after-sales service. The fact that Shure has maintained its pioneering role as the leader in microphones is the result of long years of cultivation and accumulation. Today, Shure still carries out the belief that "The Performance Never Ends" to create a better tomorrow. Shure started as a wholesaler, and in 1925 Shure (S.N. Shure) established Shure Brothers Incorporated in Illinois, U.S.A., which wholesaled radio components to small, family-owned businesses that assembled radios. It was in the 1930s that the company shifted from wholesaling to manufacturing. The Great Depression in the United States in the 1930's and the market shift from home to factory radio assembly led to a new direction for Shure - the manufacture of microphones. 1932 saw the introduction of Shure's first products, the double pushbutton carbon-finish microphone, which made Shure a leader in the industry. The introduction of condenser microphones, crystal microphones, and unidirectional microphones made with the aid of a single component made Shure a pioneer in the global microphone manufacturing industry. Over the years, Shure has introduced a wide range of residential and professional products to meet the market's diverse needs in audio applications, with more than 100 varieties. Shure microphone overall can be divided into music and performance (such as PA, BG series), fixed installation (such as Unispherre565 series), studio and venue products (such as UHF high-frequency microphone), wireless systems and conference systems, such as the five categories. Shure microphones are renowned for their excellent performance and rich variety. Its SM58 microphone has been the first choice of professional performers all over the world, and it is justly known for its vivid and powerful sound and rugged and reliable performance. And the famous "55SH" system is a classical design, excellent performance has become the world's heads of state in the world rostrum designated choice of products. Successive U.S. presidents, including Kennedy, Nixon and Clinton, have used Shure microphones to deliver important speeches. In recent years, in order to adapt to the changes of the times and market demand, in addition to microphones, Shure also launched a number of related products, such as mixers, signal processors, monitors and other accessories. At the same time, the company's management has been committed to improving product quality, investing heavily in staff training, improving facilities, and meeting customer needs with high quality, long-lasting service levels. The company believes in the concepts of "There is no limit to entrepreneurship" and "All success comes from the trust and support of our customers". Shure's E series and SE series of moving-iron headphones have been favored by music enthusiasts, and in 2009, Shure launched the SRH series of headband moving-coil headphones, with the SRH240, SRH440, SRH750DJ, and SRH840 in descending order from the low-end to the high-end models. whether they can revive Shure's glory in the field of moving-iron, let's wait and see.

They are closed, up to 25dB of sound insulation, even if you are in the rumbling train, the airplane can not feel the presence of outside noise. These earbuds are somewhat free from the inherent shortcomings of the structure of the earbuds themselves, and are fully comparable to some of the top large dynamic headphones in terms of soundstage positioning and openness, and sound fidelity. The company's products are not only used for music appreciation, in many hospitals, the special earplugs used for audiometry, are all products of the company. Westone Manufacturer Background Westone is a professional R&D ear device manufacturer in the U.S. Westone has more than 30 years of experience in researching acoustic devices, which have always been widely used in the professional field, and it was not until recent years that they have been promoted to the civilian market, so that the general music lovers can finally try out Westone earplugs' sound quality and wide soundstage at a popular price. And Etymotio (Etymotio) ER4, ER6, ER6i. Shure (Shure) E5, E3 and other headphones. All of them use moving-iron units, but Westone has the world's first creation of the most advanced 2-way sound splitting and 3-way sound splitting technology. Unlike general moving coil headphones, the moving iron type of pronunciation unit can be made very small, so you can put 2 or even 3 units into each side of the sound channel, respectively responsible for high, low and sound field processing. The sound effect is comparable to that of a premium speaker system. In addition, the Westone earbuds have an incredible 25dB of sound isolation, allowing you to listen to music in any noisy environment. The volume required is half that of normal headphones. There is no need to turn up the volume to dangerous levels to cover external noise, minimizing the load on your ears.
Product Description Westone, a manufacturer of ear molds for music headphones and ear molds for medical devices, offers the UM1 as an entry-level, non-customized, in-ear earbud.

After that, Shure launched the SE series on top of the ExC, with more exquisite workmanship and better sound quality.
A moving-iron headphone is a headphone that vibrates and produces sound by conducting through a precision-structured connecting rod to the center point of a miniature diaphragm. Moving-iron headphones fit easily into the ear canal due to the much smaller size of the unit. This effectively reduces the area of the in-ear portion of the headphones to fit deeper into the ear canal. The geometry of the ear canal is much simpler than that of the auricle, and is more circular in shape, so a soft silicone sleeve can provide good sound isolation and prevent sound leakage compared to traditional earbuds.
Inside the Moving Iron earbuds, the voice coil is wound around a precision piece of iron in the center of a permanent magnetic field called the "balance armature". This piece of iron under the action of magnetic force to drive the diaphragm sound. While the moving coil drives the diaphragm directly, the moving iron is conducted through a precision-constructed connecting rod to the center of a miniature diaphragm, which vibrates and produces sound.
Moving-iron headphones are actually not a new technology, it was used in the earliest days of the telephone earpiece, and then widely used by hearing aids, only in the last decade or so gradually applied to music listening earbuds. It is not the same as the driving diaphragm of moving coil headphones, the voice coil inside the moving iron earbuds is wrapped around a piece of iron located in the center of the permanent magnetic field called the balance armature, the armature is actually the moving iron unit, and this armature is driven by the role of magnetic force to produce sound.
It uses an electromagnet to generate an alternating magnetic field, and the vibrating part is a piece of iron suspended in front of the electromagnet, and the signal passing through the electromagnet causes the magnetic field of the magnet to change, which causes the piece of patch to vibrate and make sound. Dynamic iron unit can be made very small, so can put more than one unit into each ear shell, which is often referred to as 2 units, 3 units, 4 units and other multi-unit dynamic iron headset.
The vibration of moving iron headphones is more efficient, so the response speed is very fast, for the details of the playback is more excellent, it is very good at expressing the details of the sound and sense of hierarchy. But its sound lack of musicality, timbre cold less warm, lack of certain emotions and momentum performance; moving iron earbuds frequency response range is also relatively narrow, but because of its sound unit volume is very small, so in the use of more than one unit through the crossover line, to be able to improve the sound, the frequency response range is also widened some.
Moving iron headphones also because of the limitations of the principle of sound, can only be designed to become a closed structure, and for the earbuds, he could not be used to make open and headset. The high manufacturing cost of moving-iron headphones has never been a mainstream listening product for mass users, but because of the many advantages of moving-iron headphones, it has always been a niche music enthusiasts' pets. However, as music listening continues to popularize and the pursuit of high-quality sound continues to improve, more and more people are beginning to pay attention to moving iron headset products.
The difference between moving coil headphones and moving iron headphones
So from the above, we can easily see the difference between moving iron headphones and moving coil headphones, just when they are introduced separately may be slightly abstract, and not so intuitive, so we take the following moving iron headphones with moving coil headphones compared to what advantages and disadvantages to make it easier for everyone to understand the difference between the two headphones. Sensitivity: the structure of the moving iron unit is almost a closed container, only need a small current can drive it, so the sensitivity is also more dominant moving iron headphones. Acoustic music sense: universal piece of moving coil headphones have a better sense of music, while the sound of moving iron headphones is cold and hard, but rounded and smooth, indeed, moving iron headphones have this problem, making the sound of the emotional performance is not so prominent. Soundstage: due to the moving iron headphones are closed structure, in the momentum of the performance has been a defect, moving coil structure headphones in this regard is better, especially high-end open dynamic headphones undoubtedly has an absolute advantage. Resolution: resolution has always been a good advantage of the moving iron headphones, for the sound details of the playback of excellent performance. And universal moving coil structure headphones in the details of the control is not so outstanding Level: moving iron headphones itself rich in detail sound cold, it's level distribution is also more clear, will not have a smooth sense of excess like moving coil headphones. Sound density: moving coil headphones sound density is slightly loose, not compact enough, while the performance of moving iron headphones in this regard is significantly stronger than it is a lot stronger, a good sense of compactness. Frequency response speed: moving iron headphones vibration efficiency, so the corresponding speed of the moving coil headphones faster, in the transient performance is also more rapid. Frequency response range: frequency response range is narrower has been the weakness of moving-iron headphones, good moving-coil structure headphones can even break through the human ear hearing range to achieve a wider frequency response range. But moving iron headphones can be stacked and crossover technology to make up for some of the defects of the frequency response range. Frequency Response Curve: Moving coil headphone units are combined with coils through glue, and the frequency response curve will change in different temperatures and humidity, as well as in the course of use. Dynamic iron units, on the other hand, are made of metal for better stability and more reliable sound quality. Sound insulation: the unit of moving coil headphones has a larger area and requires more space and air to participate in the vibration process, so it can't guarantee excellent sound insulation. Moving iron headphones can effectively reduce the area of the ear part, and can be put into the root of the deep part of the ear canal, so the sound insulation effect is naturally more dominant moving iron headphones. Good soundproof headphones physical noise reduction performance can reach dozens of decibels, which is incomparable to moving coil headphones. Volume: the characteristics of the moving iron unit leads to moving iron headphones can only be earbud structure, and the volume is very small, and even a very small moving coil headphones are also very difficult to be able to achieve a single element of the kind of volume of moving iron headphones. Price: moving iron unit due to the complexity of the manufacturing process, the cost is high, so in terms of selling price has been a lot of people find it difficult to accept, even the cheapest moving iron headphones have to be a few hundred dollars, which is the first few years it is not easy to popularize the reason. And the cheapest moving coil headphones can even be bought for a few dollars, which can be a world of difference. But in recent years the price of moving-iron headphones is gradually declining, and with the increasing number of audiophiles, this situation has gradually appeared to change.
Moving iron should be how to boil this aspect until now there is no clear conclusion. Moving iron earplugs and moving coil, the same need for a boil process can enter a stable state. "Boil" and moving coil moving iron has nothing to do with, it is the significance of the mechanical grinding of the headset, to achieve a relatively mature and stable state. Moving iron headphones relative to moving coil, moving coil earbuds before and after the pot pot may appear relatively large changes in the sound, may pot after the sound more natural, smooth, three-frequency articulation is more fluent, low-frequency potential to increase, but the change is mainly the amount of aspects of the special construction of the moving iron unit, the sound of the style of the orientation of the basic stereotypes, basically impossible to like EX01 as a huge shift.
It is worth mentioning that, at present, there are already brands that can combine these two types of energy exchange perfectly, the combination of moving iron + moving coil makes the advantages of the two earbuds combined together, not only to ensure that the moving coil of the sense of music, but also to ensure that the resolution of the moving iron is undoubtedly very perfect, the AKG K3003 is such a revolutionary representative. However, this tens of thousands of dollars in earplugs products are also considered the top of the earplugs, not the average person can afford the price, but perhaps in the near future, this combination of the advantages of the coil-iron earplugs gradually mature, after the cost down, may be popularized, we are very much looking forward to.
Moving iron headphones use an electromagnet to generate an alternating magnetic field, the vibration part is an iron piece suspended in front of the electromagnet, the signal passes through the electromagnet will make the electromagnet magnetic field changes, so that the iron piece drives the diaphragm vibration of the sound. Its advantages are small distortion, high sensitivity, small size, high efficiency, low energy loss, the disadvantage is the high cost, commonly used in high-end headphones. More advanced moving-iron earbuds use double-balanced armature drivers to deliver studio-quality sound. Sound-wise, moving iron has greater resolution than traditional moving coil. For the same music, moving coils show the melody of a violin, and moving irons can show the melody plus the end notes of the string pull. Work efficiency is good, with an ordinary telephone interface without ear amplification can be pushed, so there are many singers in concert will use moving iron headphones as monitoring headphones. Sound, moving iron advantage lies in the middle and high frequency part of the sound density, response speed and accuracy than the traditional moving coil has an advantage, which is created by the principle of moving iron sound advantages, but the same also caused by the frequency response range is narrower, low-frequency overtones are insufficient such shortcomings. Frequency response range can be solved by stacking the number of units, but the naturalness of the low-frequency and overtones has always been one of the hard wounds of the moving iron.
As we all know, the core component of the headset is the speaker, we usually see the moving coil headphones inside the sound unit is generally moving coil speakers, moving iron headphones are moving iron speakers. Both are energized coils in the changing magnetic field to drive the diaphragm vibration and sound, the difference is that the coil of the moving coil unit attached to the diaphragm directly drive the diaphragm, moving iron horn coil is in the balance of the armature, through a connecting rod to drive the diaphragm. Moving iron unit diaphragm vibration does not need to overcome the resistance of the coil, so the response is more sensitive, more accurate, the volume is also more compact.
The moving iron was developed from the moving coil. The earliest is some hearing aid manufacturers to take the moving iron unit to do earbuds, and thus recognized by most users, the overall price point pulled to more than a thousand dollars, successfully positioning the moving iron earbuds as a representative of high-end earbuds. Relative to moving coil headphones, moving iron headphones sound high precision, bringing higher resolution, as if many people look at the first time a SLR photo, the picture is clearer and brighter, richer details. And moving coil after continuous development, with the advancement of material engineering and process technology, to overcome the instantaneous response speed and precision on the slightly poor, as well as the frequency response curve is not stable defects. The only drawback is that the moving coil in the middle and high frequency part of the sound is still insufficient compared to the moving iron, but in the low-frequency, moving coil overtones and the depth of the dive has a clear advantage, can create a very good infectious and shocking, the overall sense of hearing will also have a kind of loose and natural feeling, which is the principle of the sound of moving coil advantages brought about by the principle of sound. For example, Sony's MDR-EX90 first deflection cavity structure, the success of the large-diameter unit introduced to the in-ear earbuds, sound quality compared to the traditional moving coil to have a very big improvement in the resolution and overall quality of the dynamic iron earbuds at the same price beyond the full, but also let other headphones factory to see the possibility of high-end moving coil earbuds.
