HiFi Man Susvara Planar Headphones is a gorgeously designed, premium engineered model that truly delivers a stunning sound performance. The model's superior ergonomic design offers unparalleled comfort so you can enjoy your headphones for as long as you desire. Acoustic Performance For the first time ever in a Susvara design, an advanced magnet design has been introduced which offers a crystal clear acoustic performance due to significantly minimising pesky wave diffraction turbulence. As a result, you can sit back and enjoy a rich, beautiful sound from your music that is free from distortion. Superbly Low Mass Driver The driver design is truly astounding. Measuring in at a width of a millionth of a metre, the driver's amazing thinness, and low mass means that it creates an excitingly dynamic performance and brilliantly low distortion. Window Shade Design The brand's unique 'Window Shade' design has been specially designed to avoid resonant frequencies. This means that you can enjoy pristine sound quality while the super-delicate diaphragm is protected. Nanometer Grade The driver's incredible thinness, less than a millionth of a meter and extremely low mass means it can produce tremendously low distortion levels yet offer a highly dynamic response. Through harmoniously fusing this diaphragm with Stealth Magnet technology, the music reproduction is given impressive tonal quality and transparency.
