ZE3000A new classic audiophile-grade truly wireless earbuds with its sound designed based on the latest research results in acoustic engineering and psychoacoustics.
The ZE3000 takes its name from the E3000, the brand's most widely recognized wired earphones, which have sold hundreds of thousands of units since its launch in 2017 and have won an unprecedented ten consecutive Gold medals at Japan's largest audio awards, the VGP. At the time of the E3000's launch, most earphones in the same price range were designed to make an impactful impression at first listen, with an ostentatious sound that emphasizes both the low and the high frequencies. In contrast, we've chosen to create a natural sound that does not purposely emphasize any frequencies for the E3000, but to create a sound which is pleasant to be listened to based on scientific knowledge of acoustic engineering and psychoacoustics. It is not designed to bring an impactful surprise at first listen, but it is designed to allow you to concentrate on enjoying your music, and as a result, it's been highly praised by end users, especially on social media, and eventually has become the absolute reference at the segment. When we started to design the ZE3000, without a doubt, we set our goal to surpass the sound quality of the E3000.
Newly Designed Driver "f-Core for Wireless" to Realize Ultra-Low Distortion
Truly wireless earbuds often rely heavily on software equalization to adjust the sound characteristic, which generates issues that can be a side-effect and lead to a tiring listening experience. With the ZE3000, instead of fully depending on the equalizer, we've improved the fundamental performance of the driver units and optimized the acoustic space inside the earbuds to perfect the sound quality so that it is satisfying enough to listen to and equalizer is only utilized to make precise pinpoint effective corrections in narrow bands. However, in order to make the best use of this equalizer pinpoint correction, a driver unit with extremely high precision sound pressure frequency characteristics is required. If there is a variation of about 3dB level, which is the typical accuracy, the equalizer correction will lead to unnatural results. In order to solve this problem, we have developed a new "f-Core for Wireless " driver, which has been manufactured from scratch to achieve ultra-low distortion. Typically, the diaphragm of an earphone is made through monolithic injection molding where plastic material is injected into a mold with the center and surround are formed at the same time.However, in the case of small-diameter driver units, tangential corrugations are normally added on the surround to stabilize the movement of higher amplitude resulting in a rotational movement of the diaphragm that causes distortion. In the case of "f-Core for Wireless", the center is made of a special resin that is both light and hard. The surround of the diaphragm is made of a special, extremely flexible silicone, which ensures smooth and undistorted diaphragm movement. With the combination of these 2 special materials, despite its 6mm diameter, the area of effect of its center is equivalent to that of a 9mm diameter monolithic injection molded diaphragm. This also contributes to the reduction of distortion. In addition, the special silicone surround and center are directly molded together without the use of adhesives, which improves assembly accuracy and significantly reduces weight, thus contributing to a reduction in distortion.
"f-LINK Damping System" to Optimize Internal Pressure of the Acoustic Chamber
Truly wireless earbuds are having batteries, electronic circuit boards and antennas occupying most of the space inside the housing. This means that there is less freedom to create a perfect acoustic chamber to achieve a high quality sound. In addition, the waterproof feature which is commonly expected is forcing the housing to be completely sealed without a single vent to regulate the air pressure inside the acoustic chamber resulting the low-frequency sound becoming overwhelming and causing the overall clarity to degrade due to the auditory masking effect. Most manufacturers opt to increase the high frequencies in order to balance up the overall sound presentation and eventually the sound becomes overemphasized on both low and high frequencies, resulting a less natural sound with a tendency for vocals to become distant.
The ZE3000 features a new "f-LINK Damping System" that optimizes the pressure in the acoustic space inside the earbuds housing to create a sound equivalent to wired earphones without the need for external vents. This makes it possible to properly control the low frequencies that were difficult to achieve with the sound quality design of truly wireless earbuds, and reproduce vocals that tend to be far away in the balance intended by the artist. In addition, even in low-frequency reproduction such as drum kicks and bass lines, combined with the ultra-low distortion of the driver unit, we have achieved high quality that allows you to feel the fine and detailed expression of the bass range.
Convenient Touch Media Control
The ZE3000 supports touch operation, so you can easily operate music play / stop / volume up / volume down / next track / previous track and call / end call. The touch point is on the triangle-like surface on the faceplate of the earbuds (the side where the logo is not printed), and this design is to avoid erroneous operation when wearing it.
