The FiiO LC-4.4C upgrade cable is designed for use with 4.4 mm balanced connectors. Its standout feature is the 100% hand-braided 8-core construction, made from high-purity monocrystalline silver-plated copper, which enhances both durability and audio signal transmission quality. Each of the 8 cores is hand-braided with care, and each core contains 19 strands of 0.95 mm signal wire, giving the cable a total of 152 strands for high conductivity and stable performance.

The outer sheath is made from German TPU, known for its durability and flexibility, allowing the cable to withstand sweat and moisture comfortably during everyday use.

In terms of sound quality, using the FiiO LC-4.4C results in a noticeably smoother and more fluid tonality, reducing harsh treble and making the highs sound more refined and pleasant. It enhances musical detail and vocal clarity, giving an overall warmer tonal character.

Additionally, the MMCX connectors are marked with red and blue rings to help users easily identify left and right channels—blue for left, red for right—while also adding a visually appealing touch to the overall design.
