An closed back headphone with accurate sound, titanium drivers and comfort to wear all day. A balanced cable provides a more powerful sound!
The black PRO 900 is our reference headphone for the professional sector and has already proven its high quality sound performance in practice all over the world.
These head- phones are the first closed-back PRO headphones of Ultrasone with the new S-LogicTM Plus technology. As all Ultrasone PRO headphones, the PRO 900 also comes with useful accessories. The PRO 900 ́s hard case is equipped with extra earpads with great isolation, detachable USC (ultra soft) cable and Neutrik connectors. The titanium-plated drivers guarantee unlimited precision in sound reproduction.
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 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™ 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.
HOW DOES S-LOGIC™ WORK?
S-Logic™ sends music around your head not just into it, because this technology uses decentralised driver positioning. Did you know that you use and need the outer ear for your 3-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 3-dimensional sound. S-Logic™ is the only headphone system which addresses 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.
HOW DOES S-LOGIC™ PLUS WORK?
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 technology combines precision dampening with micro-acoustic reinforcement, allowing driver, bufferboard, 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.
To understand what ULE-technology does, you need to know that drivers in normal headphones produce low-frequency magnetic fields as they convert electrical signals into the acoustic signals you hear as music. Although the scientific jury´s still out as to damage this magnetic radiation could do to people who wear headphones for long periods of time, Ultrasone headphones employ the ULE-technology.
ULE stands for Ultra Low Emission. Originally Ultrasone developed this technology mainly for professionals as they do spend half of their lives in headphones. The average magnetic field emission of many headphones is more than four times the maximum of recommended levels. The MU Metal shielding reduces magnetic radiation by up to 98% compared to current headphones. Due to overwhelming consumer demand, we are pleased to offer ULE in all other Ultrasone lines as standard.
This patented technology has stood the test of international review and is recommended by technical surveillance organisations.
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. However, Ultrasone generally advises not to listen to music at high volumes to prevent hearing damage.
