Engineered with a powerful neodymium magnet, a Japanese voice coil and an ultra-lightweight 40 mm diaphragm, resulting in high sensitivity and detailed sound. The sound is clear and vibrant and emphasises the listening experience. The Speaker Unit housing is injection-moulded from durable ABS material and coated with rubber to give a matte look with a soft feeling. Both plugs feature a cable lock that securely locks the cable in place.
