Audio Technica SOLID BASS Inner Ear Headphones White ATH-CKS770 WH

Dual Magnetic Field Driver. Two opposing magnets create a fusion point where their magnetic forces converge. The increasing magnetic force drives the large-diameter driver with powerful and precise drive, producing a rich, tight bass sound. Multi-transition diaphragm dedicated to deep bass reproduction. Three-dimensional analysis is used to disperse specific unnecessary resonance points. By increasing the effective vibration area, deep bass reproduction is achieved that exceeds the driver diameter. Aerobase Bending System. Vents (air holes) are placed in the best position according to the driver characteristics. This optimizes the air springiness inside the housing and improves bass output efficiency. Uses a robust, machined solid aluminum enclosure.
