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

Equipped with a newly developed Φ13mm DUAL MAGNETIC-FIELD DRIVER. Refined high-magnetic-force design and vibration-damping structure deliver revolutionary deep bass reproduction. Dual Magnetic Field Driver. Two opposing magnets create a fusion point that maximizes magnetic force. This increased magnetic force drives the large-diameter driver with powerful and precise drive, producing rich, tight bass. Multi-transition diaphragm dedicated to deep bass reproduction. Three-dimensional analysis disperses specific unwanted resonance points. By maximizing the effective vibration area, deep bass reproduction is achieved beyond the driver diameter. Aerobase Vending System. Vents (air holes) are positioned optimally according to the driver's characteristics. This optimizes the air springiness inside the housing and improves bass output efficiency. Features a robust, machined solid aluminum enclosure.
