FIIO FD15

Introducing the FD15, a flagship earphone that redefines the boundaries of high-end audio. At its core is a revolutionary diaphragm design, combining magnalium and DLC (Diamond-Like Carbon) gaskets to deliver a spacious and natural soundstage with unparalleled detail and transparency.

FIIO's pursuit of acoustic excellence is evident in the FD15's innovative design, which incorporates a W-shaped gasket structure that increases the effective vibrating area by 30% compared to conventional earphones of the same size. This results in a denser, more solid listening experience with greater bass response.

The FD15 takes immersion to new heights with its F.T.B.S. 'Tesla Valve' bass enhancement design, which utilizes precision powder metallurgy to create a unique fluid structure that extends bass frequencies. The earphone's carefully calculated channel layout and high-precision manufacturing process ensure a detailed and deep bass experience.

The FD15's design language is as striking as it is elegant, with a closed-back acoustic design that features intricate flourishes and precise surface finishes. Crafted from 316L medical-grade stainless steel and undergoes meticulous hand-polishing and PVD electroplating, the IEM boasts a premium finish that is both durable and visually stunning. Available in obsidian black and racing silver, it's a stylish accessory that makes a statement.

For audiophiles seeking authentic connectivity, the FD15 comes with a high-quality cable (LC-RC 2024) made from Furukawa's renowned monocrystalline copper, which has gained worldwide acclaim for its clarity and accuracy. The cable features four large strands of 100 copper wires and 20 silver-plated wires for an overall total of 480 wires, making it unparalleled in its class. With a cross-sectional area of 22AWG and high-temperature smelting at 1050°C, this cable delivers exceptional quality at an affordable price.
