Character  
Eye-catching exclusive design and sand-grey coated. The HFI-680 catches the eye and 

enjoys your ears with an extraordinary balanced, natural and detailed sound image. 
Experience the complete isolation of closed-back headphones and the honest sound of 
open ones. The high class gold-plated drivers of the HFI-680 are very sensitive and 

provide a maximum of transparency. 
 

 

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.
