Oyaide Extension headphone cables 1/4" TRS plug- 3.5mm F plug HPSC-63J 1.3m

When you use a headphone or an earphone, there may be some occasions that the length of the cable is not long enough and an extension cable would be needed. However, there are no high-quality extension cables in the market, so you must accept the degradation of sound quality or limitation of listening position.


Responding users voice who wait for high quality extension cable, we at Oyaide achieved to produce HPC-35J/62J which help for signal transmission as little loss as possible.

The core component of the HPC-35J/62J is J-3.5SR, the newly-developed 3.5mm female plug. It is produced pursuing sound quality and made of accurately machined copper alloy with silver + rhodium plating.

For the cable of HPC-35HD598/62HD598, we applied Oyaide original HPC-22W which became a standard of headphone cable. By its high-quality PCOCC-A conductor, electrically superior PFA insulator, flexible and rigid TPE outer sheath, it has great sound quality and usability.

In order to respond to various using situations, we prepared 2 different length (1.3ｍ/2.5m) and 2 different kind of plugs (3.5mm stereo mini and 1/4 TRS phone). For both plugs, we applied silver + rhodium combination plating which has been proved its superiority by application for other HPC-series.

We use our original audio grade solder, SS-47 for the connection of plugs and cables of 「HPC-35J/62J」. Compared to general solders which usually contain 3N (99.9%) pure tin, SS-47 contains 4N (99.993%) pure tin achieved by excluding impurities to the maximum. Furthermore, 4.7% silver and 1.7% copper are contained for the purpose of improvement of electric conductivity and durability.
