A New Classic Audiophile-Grade Truly Wireless Earbuds

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.

The ZE3000’s “f-LINK Damping System” creates a natural sound similar to that of wired earphones, while the newly developed “f-Core for Wireless” driver unit delivers ultra-low distortion, resulting in a sound quality that is unmistakably different from conventional truly wireless earbuds. We want to convey the intentions of artists and creators as they are by creating a clear and natural sound through ultra-low distortion. In addition, the shape of the housing and the ear tips “TYPE E Truly Wireless Exclusive Edition”, has been cultivated through the development of wired in-ear earphones to achieve excellent wearing comfort, suppress external noise and achieve excellent noise isolation performance.

Newly Designed Driver “f-Core for Wireless” to Realize Ultra-Low Distortion

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 the equalizer is only utilized to make precise pinpoint effective corrections in narrow bands. 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. 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. 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 we have achieved high quality that allows you to feel the fine and detailed expression of the bass range.

2 Color Variations with Premium Shibo finish

2 color variations, BLACK and WHITE. Although the earbuds body and charging case are lightweight resin housings, they have a soft-textured Shibo* coating reminiscent of the parts of a high-end camera. Normally, such Shibo coating is applied only on a metal surface, but we have developed and realized a special process that can also be applied to the resin surface.

* Shibo; an old Japanese word meaning a wrinkle on the surface of paper or leather.
