The FiiO TRUST Series LL-3.5A is a premium 3.5mm to 3.5mm stereo audio cable featuring silver-plated oxygen-free copper conductors, graphene + pure copper shielding, and a seamless injection-molded FiiO Arc design plug. Available in 500mm, 1000mm, and 1500mm lengths, it delivers clean, interference-free analog audio signal for portable DAPs, DAC/AMP units, smartphones, and headphone amplifiers. Lab-tested to 5,000 plug/unplug cycles — backed by FiiO's decade-long HiFi engineering expertise.
FiiO TRUST Series LL-3.5A – Premium Silver-Plated 3.5mm to 3.5mm Stereo Audio Cable for Portable HiFi Systems
The FiiO TRUST Series LL-3.5A is a premium 3.5mm to 3.5mm stereo audio cable engineered for audiophiles who demand uncompromising signal quality in their portable and desktop HiFi systems. Part of FiiO's all-new TRUST Series of Cables — a line built around the philosophy of trusted quality, trusted choice, and trusted experience — the LL-3.5A delivers exceptional analog audio performance across three available lengths: 500mm (LL-3.5AS), 1000mm (LL-3.5AM), and 1500mm (LL-3.5AL).
At the core of the LL-3.5A is a high-purity silver-plated oxygen-free copper (OFC) conductor. The oxygen-free copper ensures outstanding electrical conductivity for a smooth, rich, and detailed sound reproduction, while the silver plating further enhances conductivity and improves the transfer of high-frequency audio signals — resulting in greater sound transparency and refinement. An advanced graphene + pure copper shielding layer effectively isolates external electromagnetic interference, keeping your audio signal clean and pure.
The TRUST Series LL-3.5A features a seamless injection-molded casing on every plug. The housing is manufactured from high-quality engineering plastic via precision injection molding, providing robust mechanical protection for the internal metal terminals and wiring. This construction ensures a secure, stable connection that will not loosen or detach over time, and effectively prevents cable breakage during repeated plugging and unplugging. The iconic FiiO Arc design on the plug casing is not just aesthetically distinctive — it also conforms naturally to the curve of your finger, making the cable effortless to plug and unplug even in tight spaces behind equipment.
Durability is built into every layer of the LL-3.5A. The cable features a high-elastic PVC outer sheath combined with a glossy polyester FDY (Fully-Drawn Yarn) braid — a combination of abrasion-resistant materials and a tear-proof woven structure that protects against cuts, wear, and kinks. Each internal core wire is reinforced with 500D nylon filament, significantly boosting the cable's resistance to bending stress and pull forces. The result is a soft, flexible cable that is comfortable to handle and resistant to slippage — far superior to typical hard plastic alternatives.
Every FiiO TRUST Series cable undergoes thorough testing at FiiO Labs, including 5,000 cycles of insertion-and-removal testing, salt spray corrosion tests, voltage and current tests, lifting tests, swing tests, crush tests, extreme temperature tests, and anti-oxidation tests. This rigorous lab-tested quality assurance process ensures that the LL-3.5A will perform reliably for years to come. When you choose a FiiO TRUST Series cable, you are choosing a product backed by one of the world's leading HiFi audio brands with over a decade of acoustic engineering expertise.
The FiiO TRUST LL-3.5A cable is the ideal connection solution for linking portable DAPs, smartphones, DAC/AMP units, headphone amplifiers, portable music players, and any other HiFi audio equipment with standard 3.5mm outputs and inputs. Whether you are building a dedicated portable HiFi system or upgrading the interconnects in an existing setup, the LL-3.5A delivers the signal integrity and build quality your system deserves.
