The PRO 580i provides exactly the energy needed for a massive bass boost. Thanks to patented S-Logic® PLUS technology, these headphones also provide very clear stereo reproduction and outstanding depth graduation, making the music a real spatial experience. The large 50mm sound transducer has no problem handling high input power. In terms of comfort, the headphones are even better than their predecessor the HFI 580. Thanks to the comfortable headband cushions and low weight, they are guaranteed to sit comfortably on your head. The PRO 580i also comes with interchangeable ear cushions, so you can decide for yourself whether to have your headphones with artificial leather or velour cushions.
