FiiO LC-2.5D White

Compared to common silver and 925 jewelry silver, the monocrystalline pure silver used in the LC-2.5/3.5/4.4-D is of higher silver purity and thus has better conductivity.
Each small strand of wire in the earphone cable consists of 8 Litz wires each of which are insulated from each other with a DuPont sheath, and 7 of these small strands are braided together into 1 large strand. With 4 large strands, there is a total of 224 wires in each FiiO earphone cable.
The upgrade earphone cable is available with 4.4mm balanced, 2.5mm balanced, and 3.5mm single-ended plugs to be compatible with the vast majority of music players out there today. Each type of plug comes as L-shaped for better ergonomics, and the headphone end utilizes the proven, reliable, and widely-used MMCX connectors.
