Audio-Technica SOLID BASS In-Ear Headphones, White, ATH-CKS770 WH

Dual Magnetic Field Driver. Two opposing magnets create the next fusion point where magnetic force is converted. The increased magnetic force guides the large-diameter driver to powerful and precise drive, expressing tight and rich bass. Multi-Transition Diaphragm Dedicated to Deep Bass Reproduction. Three-dimensional analysis disperses specific unwanted resonance points. By increasing the effective vibration area, it achieves deep bass reproduction that exceeds the driver diameter. Aero Base Bending System. Vents (air holes) are placed in the best position according to the driver characteristics. The air springiness inside the housing is optimized, improving the output efficiency of bass. Adopts a robust, machined solid aluminum enclosure.
