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.
ULE-Technologie & PRO Design
PRO headphones stand for Ultra Low Emission (ULE-technology) with significant benefits for professional users and PRO headphones show a specific design. The PRO 900 appearance does not only distinguish the professional line but also allows due to more ear anatomy area a higher degree of transparency in combination with the spatial sense and understanding. The PRO 900 headphones offer an additional possibility to choose a black pair of PRO headphones with black and silver velvet earpads.
To understand what ULE-technology does, you need to know that most headphone drivers produce low-frequency magnetic fields as they convert an electric signal into an acoustical signal you hear as music. In response, Ultrasone developed a special MU Metal shielding (ULE-technology) to reduce the radiation by up to 98% compared to current headphones. The ULE-technology has stood the test of international review and is recommended by technical surveillance organisations. Ultrasone originally developed the ULE-technology for professionals as they do spend half of their lives in headphones. But due to grand requests the ULE-technology has now been integrated in other Ultrasone headphone lines.
S-Logic™ does not only create a Natural Surround Sound. S-Logic™ allows at the same time a reduction of sound pressure levels by up to 40% (3-4 dB) 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.
