Oyaide HPC-QUAD 35 Headphone Cable
Best upgrade for audiophiles seeking improved clarity and signal precision.
This is a brand new, 100% genuine Oyaide HPC-QUAD 63 Headphone Cable, 1.5 meters in length, shipped directly from Japan. The cable features a 4-core star quad structure utilizing 102 SSC conductors (AWG26 / 0.13sq). The insulation is made from TPE (polyester elastomer), and silk is used for interposition. It is shielded with a silver-plated braid with a 97% ratio. The cable outer diameter is 4.0mm±0.2mm. The connectors are high-quality: the headphone amplifier side uses a 1/4 TRS phone plug, and the headphone side uses a 3.5mm mini plug. Both connectors feature brass bodies with thick silver plating (1.5μ) and rhodium plating (0.3μ) on the contacts. Original SS-47 solder is used for connections. Please note that import duties, VAT, and other associated charges are not included in the item price or shipping costs.

What customers say
Audiophiles highly value the Oyaide HPC-QUAD 35 for its superior build quality and sonic refinement. Users consistently praise the robust construction using high purity copper, suggesting excellent long term reliability. Sonically, the cable delivers noticeable improvements in clarity and detail retrieval, often resulting in a tighter, more controlled bass response and an expanded soundstage. While the cable carries a premium price, most owners feel the investment is justified by the enhanced listening experience. A minor drawback noted by some is the cable's slight stiffness, which can be less ideal for portable use. Overall, it is regarded as a top tier upgrade for critical home listening.
Know before you buy
The star quad configuration is designed to cancel out electromagnetic interference and noise. This results in a cleaner, more stable signal transmission compared to standard cable geometries.
Oyaide’s 102 SSC (Special Surface Copper) is a high-precision conductor processed to remove impurities from the copper surface. It provides excellent conductivity and a transparent, detailed sound signature.
The combination of thick silver and rhodium plating provides both high conductivity and exceptional durability. Silver ensures a low-resistance connection, while the rhodium layer prevents oxidation and resists wear over time.
This cable is designed for headphones with a standard 3.5mm TRS input. Please verify that your specific headphone model does not require a proprietary locking mechanism or a recessed jack, as the 4.0mm outer diameter and plug housing are built to standard specifications.
Silk is used as an interposition material to act as a vibration dampener. It helps reduce microphonics, which is the unwanted noise caused by the cable rubbing against clothing or surfaces.
