S-Logic® Natural Surround Sound - To hear is like to see: 3-dimensional

Unique? Yes! Revolutionary? Definitely! The patented S-Logic® technology is described as Natural Surround Sound System. No other digital surround system can compare with this standard. As the sound of a normal headphones will sound direct and even on both sides, the S-Logic® system pushes the sound around your head! It appears as though you are listening to speakers meters away. Even at very low levels, this spacious sound allows you to hear and listen to each and every individual sound. And on top of that, the S-Logic® technology does not require additional equipment!

How does S-Logic® Natural Surround Sound work?

S-Logic® sends music around your head not just into it, because this technology uses decentralized driver positioning. Did you know that you use and need the outer ear for your three-dimensional understanding to define the direction and distance where a sound comes from? Instead of hitting the inner ear directly, with S-Logic® the 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 neither need artificial echo nor digital sound processing or cross over run time delay. You can hear the sound just the way the sound engineer has mastered it.

S-Logic® does not only create a Natural Surround Sound sensation. S-Logic® allows at the same time a reduction of sound pressure levels at the eardrum by up to 40% (3 - 4 dB). This may reduce the risk of hearing damage while ensuring hours of fatigue-free listening.
