Designed for critical listening applications, the MDR7509HD headphone features newly developed HD Driver units that deliver ultra-wide dynamic range and incredible power handling capabilities. With 3,000 mW power handling capacity and 80kHz ultra high frequency reproduction, the MDR7509HD model precisely reproduces every nuance recorded using the latest generation of high-quality audio formats such as DSD or high sampling linear PCM. The 50mm HD Driver units utilize 360kJ/m3 high power neodymium magnets to reproduce clear midrange. Equally important to sound quality is wearing comfort. The MDR7509HD headphone features an Auranomic circumaural design - where the driver units have been designed in accordance with the angle of the ear, thereby helping to eliminate pressure on the ear and to reproduce a natural, wide soundscape.
