Overview

OFC copper headphone cable terminated in 6.35 mm TRS single-ended. 4-core construction with conductors twisted in two pairs and terminated single-ended (not balanced). Standard for desktop-amp single-ended use.

Lower-cost alternative to the OCC XLR4 balanced variant. Audible quality difference between OCC and OFC at this price point is largely psychoacoustic; mechanical robustness is the more meaningful differentiator.

Cup-end connector varies by model — typically dual 3.5 mm mono (standard), single 2.5 mm TRRS (HiFiMan-style), or proprietary mini-XLR.
