ULE-technology & PRO design
PRO headphones stand for Ultra Low Emission (ULE-technology) with significant
benefits for professional users and PRO headphones show a specific desighn. The PRO
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.
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™ Natural Surround Sound
Through the S-Logic™ Natural Surround Sound the usual headphone sound will be
moved out of the head in the room around you. The sound is no longer locked in, but
appears broad and detached. Directions and distances can be heard and perceived - it's
just like being in a live concert. For this new technology additional equipment is not
required. Take a pair of Ultrasone headphones plus your sound device and you will be
ready for the 3-dimensional sound enjoyment!
Safer hearing
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.
