FiiO LC-2.5D / 3.5D MMCX - 2.5 mm - 3.5 mm

Description

Monocrystalline pure silver

The LC-D cables use monocrystalline pure silver conductors instead of standard or jewelry-grade (925) silver. Higher material purity means lower electrical resistance and better signal conductivity — which translates to a more transparent, detailed sound than the typical stock cable.

224-wire Litz construction

The internal architecture is built to limit signal loss and interference. Each cable has four large strands braided together; each large strand is made of seven smaller braided strands; each of those holds eight individually insulated Litz wires — 224 conductors total per cable. Every Litz wire is individually wrapped in DuPont insulation to prevent cross-talk and keep the signal isolated from source to earphone.

Ergonomic build and compatibility

Industry-standard MMCX connectors fit a broad range of premium IEMs. The source plug is L-shaped to reduce strain on the player's jack and improve comfort during long listening sessions. Pick the LC-2.5D for 2.5 mm balanced outputs (DAPs, balanced amps) or the LC-3.5D for universal 3.5 mm single-ended sources.

Common Questions

Why choose the FiiO LC-D series pure silver cable?

For MMCX-compatible IEMs, this is a direct upgrade over the stock cable — better conductivity, more detail, and a more open soundstage.

What is the difference between the LC-2.5D and LC-3.5D models?

LC-2.5D uses a 2.5 mm balanced plug for DAPs and balanced amps; LC-3.5D uses a 3.5 mm single-ended plug for universal compatibility.

What type of earphones are compatible with these cables?

Any earphones with detachable MMCX connectors.

How does monocrystalline pure silver improve sound quality compared to standard copper?

Higher purity and conductivity than copper or jewelry silver — high-frequency details travel more efficiently, giving a more open soundstage and better tonal accuracy.
