RUF-XC is another member of RANKO USB digital audio interconnection based on advanced research and accumulated 

experience from its predecessors. The patented UIF (USB Impurity Filter) technology is adopted and progressed, 

especially for noisy transmission from mobiles, tablets, and computers.  

It can restore the authority of digital signals and immune to noise from 5V supply. 

What even more inspiring is 6N OCC silver strands used in RUF-XC. It brings the highly resolving sound signature far beyond copper counterpart. 

It also leads to a unique feature in XC, a UIF switch to alter sound presentation. When in UIF-1 position, 

it fully complies with the original form of music, in UIF-2, XC will expand the sound stage benefiting the listening experience in earphones. 

XC is another contribution from RANKO bringing the magic of music to the digital world.
