We have designed the sound quality of this product based on the latest acoustic engineering and psychological research results. Utilizing the typical method of sound creation whereby certain high frequencies are emphasized, you’re given to feel vivid sound when you first listen, but because of this, other ranges are obscured and hard to hear.

With E5000, no particular sound ranges have been emphasized, and this, together with our commitment to detailed sound expression, achieves a vast sound stage that seems to envelop you, something unthinkable in earphones up until now.

In addition, the silver-coated cable is standard equipment. With the employment of an MMCX connector that can be re-cabled, it is possible to replace the cable in the event of cable breakage.

We’ve carried out the sound design of this product based on the latest acoustic engineering and psychological research results. Using the usual method of sound creation whereby high frequencies are given a sharp peak and certain high frequencies are emphasized, you’re given to feel vivid sound when you first listen, but because of this peak, the anteroposterior ranges are masked and hard to hear. With the E series, making the arc of the frequency response smooth overall ensured that no bands were masked, and we achieved high resolution. Compared to E3000/E2000, a purer, subtler sound is achieved.

*To heighten the resolution across all ranges, acoustic pressure has been lowered. When you listen, the sound appears laid-back; turning the volume up gradually while assimilating this subtlety affords the user a comfortable listening experience. This product is one whose merits become more apparent the longer you use it.

There is an acoustic resistor inside the rear housing of the driver unit, and this controls the low mid-range frequency characteristics that determine the framework of the sound quality. At the end of this, there is a pipe bent into an L-shape (acoustic chamber) which is necessary for tuning; with this, we have achieved a balance between the volume of low frequencies and clarity.

The MMCX connector was developed in-company. We’ve used high-purity OFC silver coated cables that provide a wide sound stage. These jointly-developed cables were originally designed by and are currently manufactured by the well-renowned Junkosha corporation for the purpose of being used with the supercomputer “Kei” due to their fast signal transmission speed. The insulator film is made from PFA which was also developed by Junkosha who used their extensive know-how through the JUNFLON® brand to create the ultimate in low-permittivity material. The outer tube is made from PVC for maximum flexibility. The user will experience surprising flexibility that both makes the cable extremely easy to use as well as reducing the likelihood of microphonics. In addition, the MMCX plug and the 3.5 mm mini-plug have a tendency to disconnect so we’ve far exceeded the regular QA pass criteria of a 5,000-time bend test by changing the connection design to one that can withstand more than 50,000 bends.
* Junkosha: The Japanese corporation Junkosha develops and manufactures products such as high speed coaxial cables that boast the world’s fastest transmission speed at 95% the speed of light, as well as cables for demanding fields such as marine and aerospace, healthcare and power generation facilities. These special cables require a high level of technology and center around fluoropolymers. Junkosha’s cables are often called by the brand name JUNFLON® and have earned the tremendous trust of engineers requiring special-purpose cables.

With their swing fit mechanism, the earpieces can be swung left and right and tilted towards the audio canal for a perfect fit. These prevent changes in shape owing to the aperture of the earpiece coming into contact with the audio canal. The sound is transmitted directly to the eardrum, delivering clear sound.

The precision involved in assembling the parts for the driver unit is of the utmost importance. The small-aperture 6.4mm diameter dynamic driver unit boasts an extraordinarily high level of precision for this price range.

Machined from stainless steel and with a mirror finish, the housing firmly supports the driver unit and suppresses unnecessary vibrations; it is an important element with respect to sound quality. Fitting of a device for the mature listener, this is a design that has a simple shape and a high-quality texture matched with classic sound quality.

Two types of silicon differing in rigidity are employed for the sound conduit and for the earbud that comes into contact with the user’s ear. The silicon used for the sound conduit is more rigid than that used for the earbud, and by having groove processing applied to it, combines both strength and flexibility. Soft silicon has been employed for the earbud, making for a comfortable fit and a high level of sound insulation.
One of the bushes is gray, while the other is red; by pulling the earpiece back slightly to check the color of the bush, it is easy to distinguish between left and right, even in places with subdued lighting. Since the bush colors of neighboring sizes are different (the gray bushes alternate between dark and light gray; the red bushes alternate between red and pink), it is also easy to distinguish between sizes.Comes in 5 sizes – SS/S/M/L/LL

With similar existing products, it was assumed that they would be fitted to ears of differing sizes; not only were they large in size, their appearance was rather too distinct, and it took a lot to get accustomed to fitting them. Having considered what the key to fitting the ear hooks was, we discovered a form that was smaller than existing ear hooks, that didn’t utilize metal or resin wires and fit the ears of more people. We’ve achieved something that is slim and does not have a foreign feel to it, making for the kind of comfort that has you forgetting you’re wearing them. There’s also no problem with combining it with a figure 8 cable.
Cable noise – the unpleasant noise that occurs when the cable touches the user’s body when they are walking – is dramatically reduced.

With this silicon carry case, the cables can be rolled up and stored easily. The earphones themselves are gently secured using thin dome-shaped silicon covers.

Aging refers to the phenomenon whereby sound changes with sustained use over a set period of time. With the driver unit, the extremely thin film that is heated and shaped vibrates to create sound. The reason for this is not clear, but the stress from the adhesive and the stress applied when shaping the film settles down as it is used, and it is thought that perhaps micro-signals move more freely.

With this product, because of the small apertures, an extended length of time is necessary for changes according to aging become hard to identify. Generally, 150 ~ 200 hours of regular use increases delicacy and sound quality follows the intent of the original design.

* Since the reason for sound quality improving through aging has not been clearly established, nothing could be clearly stated about aging until now. We have been checking this phenomenon, and have decided to express our opinions so as to collect as many questions regarding aging from customers as possible.

Silicon carry case, Ear pieces (E type 5 sizes), Ear hook, Karabiner

Please refer to the earpiece swing fit mechanism while fitting the product; align the product at an angle where it fits smoothly into the ear. Please check the L (left) and R (right) indicators at the back of the left and right housings. Holding the product, fit into the ears using a slight twisting motion. Since sound quality differs greatly according to the positioning of the ear piece, move each ear phone around while playing music until you find the position with the balance that suits you best. Once you have experienced this position, it will be easier to find subsequently.

* It is usual that a person’s ears differ in shape from left to right. As such, the optimum positioning of the product differs from left to right.

With its clear, lengthy mid-to-high frequencies and wide lower frequencies, listeners can enjoy the atmosphere of musical arrangements. Compared to E3000, there is more clarity and the sound stage is even wider. You can experience the kind of immersive sound that seems to envelop you in smooth music; it’s as though you can feel the harmony of the orchestra tactilely.
