This is a discontinued model from Kousuke, a well-known individual creator on X. ■Explore Hybrid V4 ultra This cable uses a coaxial structure with silver-plated shielding and a hybrid material. While you can feel the solid high frequencies and tight low frequencies characteristic of silver, it suppresses the unique unpleasant aspects of silver, resulting in a cable that is strongly oriented towards listening. It excels particularly in high-frequency expression, making it an excellent match for earphones that excel in high frequencies and those equipped with EST drivers. However, it can reproduce all frequencies without excess or deficiency, so you won't feel a lack in the low frequencies. Rather, it's a cable that allows you to fully enjoy tight low frequencies.
