LC-RC - Interchangeable Plug Silver-Plated Monocrystalline Earphone Cable

The FiiO LC-RC is a premium upgrade and replacement earphone cable engineered for users who need flexibility, durability and improved sound clarity. Built using high-purity silver-plated monocrystalline copper conductors arranged in a Litz braided structure, the LC-RC minimizes resistance and signal distortion while promoting more accurate high-frequency resolution and cleaner overall sound.

Designed with a twist-lock interchangeable plug system, this cable lets you easily switch between 2.5 mm balanced, 3.5 mm single-ended and 4.4 mm balanced terminations to suit different portable players, DAC/amps and audio sources. The outer sheath is made from a high-quality TPU material that resists yellowing and stiffening over time, while the flexible braiding provides long-lasting reliability and everyday usability.

Whether you’re replacing a worn-out stock cable or upgrading your current setup for broader compatibility and improved signal transmission, the LC-RC delivers a balanced, detailed listening experience with robust build quality.
