Fiio RC-78B, In-Ear Monitors Replacement Cable: for Westone UM3XRC, W4R, 2.5mm Balanced Cable (RC78B, RC 7BB)

Fiio RC-78B 2.5mm Balanced earphone replacement cable for Westone UM3XRC / W4R / NF Aduio NF2 NF3 NF4 / JH13 16 / Earsonic

Technical Features

The RC-78B swaps the standard 3.5mm stereo jack for a 2.5mm 4-pole plug. With its separate Left/Right channel wires and separate +/- signal transfer, the RC-78B enables balanced operation for your earphones. When connected to a balanced headphone amplifier, RC-78B can greatly enhance channel separation as well as markedly increase the signal to noise ratio. This results in a wider sound stage and more controlled, textured bass - perfect for balanced output enthusiasts.

The RC-78B adopts Teflon*FEP (fluoridated ethylene propylene) for the sheath and silver-plated copper as the conductor. 11 strands of silver-plated copper wires (each with a diameter >0.08mm) make up each of the 8 separate cables, which are all woven into one audio cable with separate wires for the Left/Right channels. Both the straight 2.5mm plug and CIEM conductor (with a 0.78mm diameter) are made of gold-plated copper. These premium choices of materials ensure the RC-78B is a high-quality cable that is highly elastic, tough against scrapes, and resistant to aging.

Design

From the plug joint, to the Y-splitter, to the earphone-side connector, the RC-78B is wrapped with transparent polycarbonate to separate itself from the unicolour cable. Not only does this striking visual element give earphones some character, it naturally also invites a closer look with its revealing view of the insides.
