Audio-Technica SOLID BASS In-Ear Headphones, Red, ATH-CKS770 RD

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 precision, producing rich, tight bass. Multi-transition diaphragm designed specifically for deep bass reproduction. Three-dimensional analysis disperses specific unwanted resonance points. By maximizing the effective vibrating area, deep bass reproduction is achieved beyond the driver's diameter. Aerobase Vending System. Vents are optimally positioned to match the driver's characteristics. This optimizes the air springiness within the housing and improves bass output efficiency. Uses a robust, machined solid aluminum enclosure. Country of Origin: China
