Product features ★ A large capacity cutting aluminum housing excellent in vibration damping performance and a heavy bass feeling with the body with the base booster realized. ◆ Smartphone compatible ● Handsfree call with smartphone, music operation with remote control is possible ◆ “Base booster” to convey the deep bass’s groove feeling without spending part ● Optimized the operation of the low-frequency diaphragm by the duct provided on the housing while increasing the airtightness from the driver unit to the eardrum. ● By grasping the overwhelming sense of volume bass with accurate rhythm, we will convey the sense of depth of deep bass directly. ◆ Aluminum housing excellent in vibration damping properties ● By enlarging the housing made of cutting aluminum, it realizes a sound that balances smooth low-frequency response and clear, glossy middle-high range. ◆ Originally developed miniature, high sensitivity 12 mm driver unit ● Adopting a proprietary 12 mm driver, it achieves a dome area of the same size as the 16 mm driver unit. ◆ High magnetic neodymium magnet ● 360 kJ / m 3 high magnetic neodymium magnet of the same size as the 16 mm driver unit and a long voice coil that stabilizes the grounding with the magnet, longer than the conventional voice coil. ◆ Angled ear type system ● The miniaturization of the driver realizes the angled earpiece system. Since it can be fitted to the back of the ear, the sound insulation improves, and comfortable wearing feeling and high sound quality are compatible at the same time. ◆ Hybrid earpiece to improve fit and sound quality ● Part of the core uses hard material to keep the shape of the sound passage, preventing sound degradation due to collapse of the tip. ● The outer part improves the fit to the ear by using a soft material. ※
