[Sound Creation Based on Acoustic Engineering and Psychology] The sound quality was designed based on the latest 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 harshness. *The sound pressure is lower to enhance resolution across all frequency ranges. While it may sound subdued at first listen, gradually increasing the sound pressure while appreciating its subtleties will result in a comfortable listening experience. This is a product whose merits become more apparent the longer you use it. [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 frequencies that determine the structure of the sound quality. Beyond this is an L-shaped space, the key to tuning, which achieves both volume and clarity in the low frequencies. [MMCX Connector + Original OFC Cable] The MMCX connector was developed in-house. The cable is made with a soft, flexible sheath to reduce touch noise. It bends flexibly even when using ear hooks, ensuring a comfortable fit. [High-rigidity machined aluminum housing] The housing is machined from aluminum with an anodized finish, which provides stronger support for the driver unit and suppresses unnecessary vibrations compared to a plastic housing. As a tool for everyday use by adults, it has a simple shape and texture, and its design is consistent with what could be called classic sound quality. Sound quality designed based on the latest acoustic engineering and psychoacoustic research results. Clear sound quality across the entire frequency range, realizing a realistic and immersive experience.
