Audio Technica SOLID BASS Inner Ear Headphones Black BK ATH-CKS770

Dual magnetic field driver. Two opposing magnets create the next fusion point to maximize magnetic force. The increasing magnetic force guides the powerful and precise drive of the large-diameter driver, expressing a tight and rich low range. Multi-transition vibration version exclusively for deep bass reproduction. 3D analysis disperses specific unnecessary resonance points. By maximizing the effective vibration area, we achieve deep bass reproduction that exceeds the driver diameter. Aero base bending system. Vent (air hole) is placed in the best position according to driver characteristics. Optimizes the air springiness inside the housing to improve bass output efficiency. Adopts a strong machined solid aluminum enclosure
