Product features ★ Overwhelming heavy bass x next generation wearable style. ★ Wearing music with a light feeling of wearing and comfortable operation. ◆ SOLID BASS only φ9.8 mm "dual magnetic field driver" ● Two confronting magnets create a fusion point of the magnetic field that maximizes the magnetic force. The increasing magnetic force dramatically improves the driving of the driver and expresses rich low frequency. ◆ Multi-transition diaphragm for heavy bass reproduction only ● Distributed specific unnecessary resonance points by three-dimensional analysis. By maximizing effective vibration area, we realize heavy bass reproduction exceeding the driver diameter. ◆ Air flow based venting system ● Place a vent (air hole) at the best position according to the driver characteristics. Optimize the spring property of the air inside the cabinet and improve the output efficiency of the bass. ◆ Adopted new shape wearable neckband sticking to unity when attached ● We adopted a new neckband pursuing a natural cord placement that does not matter what you are wearing and a light fit. ◆ Comfortable operation with intuitive multifunction grip ● Equipped with left and right remote control that can turn on / off the power supply, play / stop, volume adjustment, call, etc. ● You can operate comfortably with a grip that you can use with your fingertips without looking at the buttons. ※ ● Detailed description: Newsbridge
