The Technology
Ultrasone´s technologies are unique. The inimitable S-LOGIC™ Natural Surround Sound and Ultra Low Emission technologies is the invention of Ultrasone. This unique system is exclusive to Ultrasone and integrates safer hearing technologies without compromising its superb audio listening environment. These are fundamental aspects to modern headphones.

S-LOGIC™ Natural Surround Sound – To Hear Is To See: 3-Dimensional
Ultrasine S-Logic LogoUnique? Yes! Revolutionary? Definitely! The patented S-LOGIC™ technology is described as a Natural Surround Sound System. No other digital surround system can compare with this standard. Conventional headphones push the sound directly into the ear from both sides, whereas the S-LOGIC™ system feeds the sound around your head and the result is that it appears as though you are listening to speaker’s metres away. Even at very low levels, the spacious sound allows you to hear each and every individual sound which offers great detail and gives you hours of fatigue free listening.
 
How Does S-LOGIC™ Natural Surround Sound Work?
S-LOGIC™ sends music around your head not just into it, this is achieved by using decentralized driver positioning. Did you know that you need the outer ear for your three-dimensional listening and understanding and to define the direction and distance of where a sound comes from? So, instead of hitting the inner ear directly, the S-LOGIC™ signals are reflected off the surface of the outer ear in different directions before entering the auditory canal to create a natural three-dimensional Sound. S-LOGIC™ is the only headphone system which includes your entire sense of hearing. S-LOGIC™ does not change your personal hearing, it intensifies it for your individual needs and listening pleasure. S-LOGIC™ does NOT employ or need artificial echo, digital sound processing or cross over run time delay.

S-LOGIC™ does not only create a Natural Surround Sound sensation, it simultaneously allows a reduction of sound pressure levels to the eardrum by up to 40% (3 - 4 dB). This can reduce the risk of hearing damage while ensuring hours of fatigue-free listening.
