Audio Technica SOLID BASS Inner Ear Headphones Blue BL ATH-CKS550

Maximum input: 100mW Type: Canal, Stereo/Monaural: Stereo, Structure: Closed type, Noise canceling: Not supported Surround: Not supported, Wireless: Not supported, Interface: Mini plug Frequency band (L): 5Hz, Frequency band (H): 24000Hz ○Dual magnetic field driver Two opposing magnets create a fusion point of magnetic fields that maximizes magnetic force. The increasing magnetic force dramatically improves the drive of the driver and expresses rich low frequencies. ○Multi-transition diaphragm dedicated to deep bass reproduction Disperses specific unnecessary resonance points through three-dimensional analysis. By maximizing the effective vibration area, we achieve deep bass reproduction that exceeds the driver diameter. ○ Air flow base venting system Vent (air hole) is placed in the best position according to the driver characteristics. Optimizes the springiness of the air inside the housing to improve bass output efficiency.
