This is the text from the catalogue:
"The MU-Metal shielding may reduce magnetic radiation by up to 98%
compared to current headphones"
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™ 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!
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 may reduce 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.
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.
