All VOVOX® sound conductors follow the same design basics. In contrast to most suppliers of cables, when optimizing our products we do not gear them to some physical values such as the ohmic resistance or capacity. That's because we have learned through much extensive testing, that the effects of a sound conductor are too complex to be reduced to a few measurables. And, it is not our target to develop cables with outstanding data sheet values, but sound conductors with the best possible sound transmission properties. The best measurement device for this purpose is definitely the human sense of hearing. VOVOX® sound conductors are hand-assembled in Switzerland. The cables, including the solder, are lead-free.
