For the discerning audiophile, ULTRASONE has equipped the sleek mobile iCans with S-Logic¿ natural surround sound technology, providing an unparalleled listening experience while protecting your hearing. S-Logic¿ unlocks the sound of your ipod and moves it into the room around you. Music is spacious and detached; distance and directions can be heard as if in a concert. S-Logic¿ Natural Surround Sound: S-logic¿ uses decentralized driver positioning to utilize the pinna of the ear in the manner it is used in everyday life, reflecting the audio signal off the surface of the outer ear in different directions before entering the auditory canal. This results in a very natural spacious three-dimensional sound. S-Logic¿ is the only headphone system which includes your entire sense of hearing. Safer Listening: Because the S-Logic¿ technology does not aim the auditory signal directly down the ear canal but at the pinna, pressure to the ear drum is decreased by up to 40% (3-4dB) for the same perceived loudness. This significantly reduces the risk of hearing damage ¿ an absolute must if you spend a lot of time in headphones. ULE technology: The ULE technology was systematically developed by ULTRASONE for users who spend many hours in the headphones. All headphone drivers produce low-frequency magnetic fields. In response, ULTRASONE developed a special MU Metal shielding (ULE technology) to reduce the radiation by up to 98% compared to ordinary headphones. The ULE technology has stood the test of international review and is recommended by technical surveillance organizations.
