The HPSC Series is a new series of headphone and portable audio cables from Oyaide Electric, introducing the precision conductors “102 SSC” and “Silk”. The precision conductor “102 SSC” is a conductor for audio cables created by Oyaide Electric and already highly acclaimed around the world.

The core of this technology is based on a type of oxygen-free copper, and includes “mechanical peeling” to physically remove 100% of impurities from the copper wire surface, a “natural diamond die” to smooth the copper wire surface to the utmost limit, two heat treatments under strict temperature control, and thorough management of wire diameter uniformity with processing precision of ±1μm or less. The HPSC Series’ clear, wide-range sound is supported by Japan’s world-class copper drawing and wire drawing processing technologies.

The signal line thickness of the 102 SSC precision conductor is a generous 0.3 scale. From delicate high frequencies to powerful low frequencies, the delicate headphone output is faithfully transmitted without stagnation. The shield is also made of the precision conductor “102 SSC” and is a spiral shield with excellent flexibility.
