Sound quality design based on the latest acoustic engineering and psychological research results. Delivers clear sound quality across all bandwidths and immersive sound that seems to envelop you.
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.
Sound creation based on acoustic engineering and psychology
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.
An acoustic chamber that is the core of low-frequency tuning
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.
MMCX Connector＆Original high purity OFC silver coated cable
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.
Unique swing-fitting earpiece mechanism
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.
6.4mmφ dynamic driver unit
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.
Highly rigid machined stainless steel housing
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.
Original earpieces with a color difference between the left and right bushes
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.
Ear hooks that alleviate cable touch noise
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.
Silicon carry case
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.
