The FiiO LC-RE Pro 2025 embodies the synthesis of audiophile sound quality, innovative technology, and precise engineering. As a high-quality in-ear headphone cable for MMCX connectors, it is based on a unique tri-metallic conductor structure made of gold-plated monocrystalline copper, pure silver, and pure copper. The exact arrangement in a ratio of 2:3:4 optimizes the sound profile: gold enhances bass transients, silver increases detail resolution in the high-frequency range, and copper provides a natural, warm midrange reproduction. A total of 360 individual wires in eight braided strands ensure outstanding signal purity with minimal impedance. Special attention is given to the integrated DSP audio decoding chip in the USB-C connector, which supports PCM signals up to 384 kHz / 32 Bit and enables an 8-band high-precision PEQ. This allows for precise sound tuning to individual listening preferences. The included interchangeable jacks in 2.5 mm, 3.5 mm, and 4.4 mm, along with the twist-lock mechanism, offer maximum flexibility when connecting to various audio sources. The MMCX connectors made of medical-grade L316 stainless steel guarantee lasting mechanical stability. With a cable length of 1.2 meters and a durable TPU sheath manufactured in Germany, the LC-RE Pro 2025 meets the highest demands for haptics, durability, and design. The precise litz braiding technique reduces electromagnetic interference and improves signal integrity across the entire frequency spectrum. The processing is carried out through a complex procedure involving high-temperature sintering, casting, and secondary melting, effectively minimizing material impurities. This manufacturing technology significantly contributes to the sound clarity and long-term stability of the cable. This premium cable is the ideal complement for high-quality in-ear headphones in both mobile and stationary use.
