The PRO 480i is the perfect introduction to the world of professional headphones. Its 40mm Mylar sound transducers provide a linear frequency of 20 Hz to 20 kHz without overemphasis or drops, reproducing music exactly as it was recorded. The closed ear cups dampen background noise effectively, making for even more intense music enjoyment. Patented S-Logic® Plus technology allows for outstandingly clear stereo reproduction and a particularly vivid bass. The PRO 480i is therefore ideally suited for both private and professional use. S-Logic® Plus is also easy on the ear and allows for long, fatigue-free listening sessions.
