S-LOGIC Technology. Invention, not improvement
The patented S-Logic technology of ULTRASONE uses decentralized transducer positioning to reflect sound off the listeners' outer ear, creating a natural three-dimensional sensation. Unlike standard headphones which create the impression of a stereo image inside the listeners' head, ULTRASONE headphones with S-Logic produce a stereophonic surround sound field that is perceived to be broad, detached and located in front of the listener.
Safe-hearing protection
The S-Logic system reduces sound pressure levels at the eardrum by up to 40% ensuring hours of fatigue-free listening, and significantly reducing the risk of hearing damage
Reduced Magnetic Field Emissions
Medical research has shown that magnetic field emissions to be hazardous to your health. The average magnetic field emissions of other headphones is more than four times the maximum recommended levels. By combining S-Logic and PROline technology, ULTRASONE has developed a method that significantly reduces up to 60%, and the certified* PROline HFI.15G version up to 98%. BY combining their unique patented S-Logic and Proline technology, ULTRASONE is the world's safest, most natural sounding headphone.
