Oyaide
Tokyo, Bunkyo-ku (Yushima), Tokyo, Japan · founded 1952
Best known in the personal-audio world for its 102 SSC precision oxygen-free copper conductor and its rhodium/gold-plated plugs and connectors, which are staples in aftermarket headphone and IEM cables — a supplier of building-block materials as much as a finished-cable brand. Independent, family-founded, and made-in-Japan since 1952, celebrating its 70th anniversary in 2022.
Oyaide Elec. Co., Ltd. is a Japanese maker of high-end audio connectors, plugs, cable, and precision conductor wire, headquartered in Bunkyo-ku (Yushima), Tokyo. Founded in 1952 as a small electrical-wire store in Tokyo’s Akihabara district by Kazuji Oyaide, the company expanded from magnet and industrial wires into audiophile-grade cables, power distribution, and connectivity products. It is widely known for its 102 SSC precision oxygen-free copper conductor and its plugs/connectors, which are used in aftermarket headphone and IEM cables. Oyaide sells both finished headphone/earphone cables (e.g., the HPSC series, formerly HPC/PCOCC-A) and bulk connectors, plugs, and wire used by other cable makers and modders. Products are exported to more than 50 countries. The company operates the OYAIDE (hi-fi) brand plus the NEO and d+ brands aimed at DJs, engineers, and musicians.
