[VGP 2021 Award-Winning Product] Winner of the VGP 2021 Earphone Grand Prize, Japan's leading audio-visual award.
[f-Core DU Driver] We established a new overseas base and redesigned driver components such as the diaphragm, voice coil, magnet, magnetic circuit, and adhesives, as well as production equipment, to develop a completely redesigned 6mm diameter dynamic driver unit [f-Core DU].
[Customized Fit] The quality of an earphone's fit is determined by the amount of pressure it provides. While ergonomically designed organic shapes and silicone-based retention methods may seem appropriate at first glance, they place constant pressure on the ears, unconsciously straining them and causing fatigue. The A4000 housing is held in place at three points for a stable fit.
[2-pin Connector] We use the φ0.78 standard, considered the most versatile. The soft, flexible sheathed material minimizes touch noise, allowing for flexible bending even when using ear hooks, ensuring a comfortable fit.
[Included Items]] A4000, silicone carry case, ear tips (TYPE E 5 sizes), ear hooks (TYPE B), 2-year warranty
