Sound quality design based on the latest acoustic engineering and psychological research results. With high definition and flat, natural sound quality, this product could be considered a "standard"
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 E3000, not creating a range that is emphasized makes for high definition and a vast soundstage. With well-balanced sound reproduction from low through to high frequencies, you can experience the same kind of sound spread you would if you listened to music in a concert hall. With this product, we've aimed at a natural sound quality for a "standard" whose value you feel the more you use it over time rather than just in its appeal when you first listen to it.
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.
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.
There is an aperture on the back of the housing which acts to extend the reproduction band of low frequencies. To prevent sound leakage from the apertures there is a filter inside, and stainless steel mesh has been added to the outside.
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. Comes in 5 sizes – SS/S/M/L/LL
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.
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.
