They come with S logic technology
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.
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.
