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.
