Product Overview

Unlock natural, organic sound dynamics with the Yongse PRISMNOIR Earphones Upgrade Cable, available now at AEHIFI. Precision-crafted for audio enthusiasts seeking pure electrical conductivity, the PRISMNOIR utilizes legendary High-Purity Furukawa Oxygen-Free Copper (OFC) conductors. Fitted with a 4.4mm balanced plug and standard 0.78mm 2Pin connectors, this cable brings smooth warmth, rich vocal texture, and a deep bass response to your favorite in-ear monitors.

Key Features & Highlights

Japanese Furukawa OFC copper is world-renowned for its exceptionally high purity and low signal degradation. The PRISMNOIR smooths out harsh upper frequencies, enriches mid-range vocals, and adds natural extension to the low end without compromising micro-detail retrieval.

Featuring a 4.4mm balanced termination, it takes full advantage of modern high-output Digital Audio Players (DAPs) and USB DAC dongles to provide maximum channel separation and a pitch-black background. Wrapped in a supple, flexible outer sleeve, the PRISMNOIR resists microphonics and tangles for long, fatigue-free listening sessions.

Technical Specifications

Sound Profile & Furukawa OFC Advantage

Furukawa OFC copper is celebrated across high-end audio for its balanced tonal character and low internal resistance. In acoustic testing, the PRISMNOIR grounds the music with full-bodied bass authority, adds organic sweetness to acoustic instruments and male/female vocals, and tames aggressive treble spikes for a non-fatiguing, immersive presentation.

The 4.4mm Pentaconn balanced configuration delivers higher drive current and eliminates cross-channel interference, enhancing both dynamic range and spatial soundstage width.
