Final Audio E4000

Sound quality design based on the latest acoustic engineering and psychological research results. Delivers clear sound quality across all bandwidths and a sense of real, true-to life sound.

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 certain high frequencies are emphasized, you’re given to feel vivid sound when you first listen, but because of this, other ranges become clouded and hard to hear.

With E4000, no particular sound ranges have been emphasized, and this, together with our commitment to detailed sound expression, results in realistic sound that sounds as if it were being played right in front of you. In addition, an MMCX connector that can be re-cabled has been employed, so that the cable can be replaced 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.

    *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.

    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 OFC cable
    The MMCX connector was developed in-company. Taking touch noise into consideration, soft, flexible coated material has been employed. When using ear hooks also, it moves flexibly, making for a good fit.


    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 aluminum housing
    Compared to a plastic housing, this housing machined from aluminum with a alumite finish firmly supports the driver unit and suppresses unnecessary vibrations. Fitting of a device for the mature listener, this is a design that has a simple shape and a high-quality texture matched with what could be termed classic sound quality.


    Original earpieces with a color difference between the left and right.
    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



    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.
