E5000

The sound quality was designed based on the latest research findings in acoustic engineering and psychoacoustics. Using common sound-creation techniques that emphasize certain high frequencies creates a sense of clarity at first listen, but this also drowns out other ranges, making them difficult to hear. The E5000 not only avoids emphasizing certain high frequencies, but also focuses thoroughly on expressing the finer details of sound, resulting in a wide, enveloping soundstage unimaginable with conventional earphones. Furthermore, a silver-coated cable is included as standard. The MMCX connector allows for easy cable replacement in the unlikely event of a cable breakage.

Sound creation based on acoustic engineering and psychology

The sound quality was designed based on new research in acoustic engineering and psychology. Using common sound-creation techniques that emphasize certain high frequencies by creating a sharp peak in the high range creates a sense of clarity at first listen, but the peak masks the surrounding frequency bands, making them difficult to hear. The E Series achieves high resolution by smoothing the overall frequency response curve, eliminating masking bands. Compared to the E3000/E2000, the sound is purer and more delicate, without any overtones. *The sound pressure is lower to enhance resolution across all frequency ranges. While the sound may initially sound subdued, gradually increasing the sound pressure while appreciating its subtleties will result in a comfortable listening experience. The longer you use this product, the more you’ll appreciate its quality.

Acoustic chamber: the key to low-frequency tuning

The internal housing on the back of the driver unit contains an acoustic resistor, which controls the characteristics of the low-mid range, which determines the framework of sound quality. Beyond this is an L-shaped bent space, which is the key to tuning, and which achieves both volume and clarity in the low range.

MMCX connector + original high-purity OFC silver-coated cable

The MMCX connector is a high-precision product developed in-house. The high-purity OFC silver-coated cable, which provides a wide sound field, was developed in collaboration with Junkosha, the renowned company known for developing and manufacturing cables for the supercomputer “Kei” due to its high signal transmission speed. The insulation coating is made of PFA fluoropolymer, a material with the lowest dielectric constant, a material Junkosha has extensive know-how for through its Junflon brand. The outer jacket is made of PVC for enhanced flexibility, achieving incredible flexibility, making it extremely easy to use and reducing touch noise. Additionally, the MMCX plug and 3.5mm mini plug, which are prone to breakage, are designed to withstand more than 50,000 bends, instead of the usual 5,000 bends required to pass.

Unique earpiece swing-fit mechanism

The swing fit mechanism allows the earpieces to be swung left and right, tilting them to fit snugly into the audio canal. This prevents deformation caused by the earpiece opening coming into contact with the audio canal. Sound is transmitted directly to the eardrum, ensuring clear sound.

6.4mmφ dynamic driver unit

Precision in the parts and assembly of the driver unit is of the utmost importance. The small-aperture 6.4φ dynamic driver unit used in this product boasts an extraordinarily high level of precision for this price range.

Highly rigid machined stainless steel housing

The housing, machined from stainless steel with a mirror finish, firmly supports the driver unit and suppresses unnecessary vibrations, an important element in sound quality.The design also matches classic sound quality with a simple form and high-quality texture befitting a tool for adults.

Earpieces with different shaft colors make it easier to distinguish between left and right

Two types of silicone with different hardness are used for the sound conduit and the earbuds that come into contact with the ear. The silicone for the sound conduit is harder than the silicone for the earbuds that come into contact with the ear, and by adding grooves to it, it combines strength and flexibility. Soft silicone is used for the earbuds that come into contact with the ear, achieving a comfortable fit and high level of sound insulation. One bush is gray and the other is red, making it easy to distinguish between left and right, even in dimly lit places, by slightly flipping the earpiece over to check the color of the bush. Additionally, adjacent sizes of bush are different colors (gray bushes alternate between dark and light gray, while red bushes alternate between red and pink), making it easy to distinguish between sizes. Five sizes are included: SS/S/M/L/LL. Choose the one that best suits your preference.

Ear hooks that eliminate cable touch noise

Previous similar products were designed to fit a variety of ear sizes, resulting in a larger size that not only stood out, but also required considerable getting used to. We reconsidered what the key to fitting the ear hooks was, and discovered a design that was smaller than previous ear hooks, did not use metal or resin wires, and fit the ears of more people with ease. Slim and unobtrusive, they are so comfortable you’ll forget you’re wearing them. They can also be used with glasses. The unpleasant rustling sound (cable touch noise) caused by the cable touching your body while walking is dramatically reduced.

Silicone carry case

This silicone carry case allows you to easily store your cable by rolling it up. The earphones are held in place by a thin, dome-shaped silicone lid.
