SOLID BASS Black BK Audio-Technica In-Ear Headphones, ATH-CKS770

Dual Magnetic Field Driver. Two opposing magnets create the next fusion point where magnetic force is maximized. This increased magnetic force guides the large-diameter driver to powerful and precise drive, resulting in tight and rich bass. A multi-transition diaphragm specifically designed for deep bass reproduction. Three-dimensional analysis disperses specific unwanted resonance points. By maximizing the effective vibration area, it achieves deep bass reproduction that exceeds the driver diameter. AeroBase Bending System. Vents (air holes) are positioned in the optimal location according to the driver characteristics. This optimizes the air spring properties inside the housing and improves the bass output efficiency. A robust, solid, machined aluminum enclosure
