ULTRASONE S-Logic PLUS Technology
The PRO 900 offers professional and unlimited sound performance. This is the first pair of Ultrasone PRO headphones with the patented S-Logic PLUS technology.
Enjoy the new standard and trust your ears...

S-Logic™ Plus is the newest advancement in the S-LogicTM 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 acoustical design of S-Logic PLUS models and their tonal fine-tuning result in maximum neutral sound impression with more vivid perception of voices and instruments.
S-Logic™ - ULTRASONE´s
Natural Surround Sound

The patented S-Logic™ technology is described as Natural Surround Sound. No other digital surround system can compare with this new standard. As the sound of 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 precisely. Edition9 uses titanium-plated drivers which offer the most accurate and finest sound reproduction. And on top, the S-Logic™ technology does not require additional electronic equipment!
How does S-Logic™ work?
S-Logic™ sends music around your head not just into it, because this technology uses decentralized driver positioning. Did you know that all of us use and need the outer ear for 3-dimensional hearing to define the direction and the 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 3-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 processing or cross over run time delay (like DSP). You can hear the music just the way the sound mixer produced it.
ULE technology - ULTRASONE´s
MU Metal shielding for reduced magnetic field emissions

ULE stands for Ultra Low Emission. The ULTRASONE ULE technology was systematically developed for professionals as they do spend half of their lives in headphones. Most headphone drivers convert an electric signal into an acoustical signal, producing 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 current headphones. All professional ULTRASONE headphones are basically equipped with the ULE technology. Certainly your Edition9 headphones may not miss the ULE technology. The exclusiveness of your Edition9 calls for the ULE standard. This patented technology has stood the test of international review and is recommended by technical surveillance organisations.
concept for safer hearing

The S-Logic™ technology does not only create a Natural Surround Sound. S-Logic™ allows at the same time a lower dB output (3-4dB) for the same loudness sensation. This may reduce the risk of hearing damage while ensuring hours of fatigue-free listening. However, ULTRASONE generally advises not to listen to music at high volumes to prevent hearing damage.
