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!
S-Logic™ Plus is the newest advancement in the S-Logic™ Natural Surround System.
S-Logic™ Plus profits directly from innovations developed for our flagship Edition range, the ultimate headphones for critical listening. This sophisticated new technology combines precision dampening with micro-acoustic reinforcement, allowing driver, buffer-board, and spatial parameters to complement one another in an optimal manner. So the acoustically redesigned ear-cups of these new models and their tonal fine-tuning result in a most neutral sound impression with more vivid perception of voices and instruments.
S-Logic EX® is a revolutionary refinement of ULTRASONE’s patented S-Logic™ technology.
This innovation is based on a funnel-shaped arrangement for the sound transducer, oriented downwards to the front. This specific funnel-shaped structure allows the transducer to be further away from the ear and therefore results in a much more spatial forward positioning effect. The main purpose of S-Logic EX® technology was to further optimise the already impressive S-Logic effect. Intensive research and many years of testing have directed in this funnel-shaped composition for the titanium-coated sound transducers, downwards to the front. These new titanium-coated sound transducers are an innovation specially adapted to this acoustic task.
