Basic Knowledge:
ULE-technology (Ultra Low Emission) - MU Metal shielding
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.
Not only PRO headphones from Ultrasone but also HFI and DJ models are equipped with the MU-Metal shielding as standard.
This patented technology has stood the test of international review and is recommended by technical surveillance organisations.
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. 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 precisely. And on top, the S-Logic™ technology does not require additional equipment!
How does S-Logic™ Natural Surround Sound 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.
S-Logic™ Plus
S-Logic™ Plus is the newest advancement in the S-Logic™ Natural Surround System, squeezing the BIG S-Logic™ soundstage found in our
PRO series headphones into the more streamlined ear-cups of select HFI & DJ models. 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.
Safer hearing
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.
