Headphones with detachable cables are enjoying a surge in popularity as audiophiles enjoy ever-greater control over their listening experience – especially in Japan – try out these high quality connects and enjoy a new listening experience. For the cable of HPC-series, the newly-produced HPC-22W cable has been employed, which has the ultrafine PCOCC-A conductors (80μ for a unit) for its high transmission property and usability.
Rather than twisting whole wires, twenty 0.08mm wires are unified in a unit and the three units are grouped as a conductor which is geometrically-stable. Herewith, it insures uniformity of wire structure, infilling of internal space and preventing deformation among the wires.
Furthermore, its diameter is 0.3sq (AWG22) which is three times bigger than a regular cable. It provides you sharp attack and hi-speed response of the sound. For the insulator of HPC-22W, 0.18mm thick PFA (Teflon) is employed for its outstanding electric characteristic and lossless transmitting capability. The metal parts of the plug are specially designed for the HSR series and made from RoHS compliant brass. After careful machine barreling, silver (inner) and rhodium (outer) are directly plated on the contact pin. These plating not only protect from corrosion but also help to improve transmitting capability.
The outer shell is carefully processed by NC machining and plated by hard chrome like a body of camera. In addition, these plugs are soldered to the cable by using "SS-47" which is an Oyaide original solder and is produced specially for audio application.
