FiiO FDX Pure beryllium diaphgram dynamic driver In-Ear Monitor (14th anniversary Edition)

Golden royal brilliance 24K gold plating

The shell of the FDX is plated with 24K gold that would not be out of place in a royal court. No matter where you go, you will surely be the center of attention with the brilliant shimmering of the gold

On another level with the pure beryllium diaphragm dynamic driver

The FDX is equipped with FiiO's latest flagship pure beryllium diaphragm dynamic driver that features exceptionally swift transient response and remarkably rich sound. This is due to its tremendous rigidity and e xtraordinary light weight being 4x more rigid than steel and 1/4 of the weight of titanium. Truly experience audio on a whole another level with the beryllium driver of the FDX.

Cupid-cut crystals 60 imitation

The FDX rear panel is inlaid with a total of 60 imitation diamonds. The Cupid heads cut into the crystals elegantly combined with the golden panel for a brilliant and sensational appearance not unlike that of a center crown jewel.

FDX exclusive high-purity braided cable in magnificent gold-silver-copper

The FDX comes with an extremely high-quality cable worthy of its special status. High purity gold, copper, and silver are combined in one cable—each of the 4 strands consists of 20 wires of each kind of metal weaved together for a grand total of 240 wires in the cable. Medical-grade TPU is used for the sheath to resist against yellowing after long-term use and against stiffening when in low-temperature environments.

Extraordinary 14th Anniversary Limited Collector's Edition

We will exhaust all efforts to make the FDX be truly a worthy piece of commemorating our 14th anniversary. Each of the limited 1000 units with unique serial numbers will be the epitome of craftsmanship, cutting-edge technology, and elegant design truly demonstrating FiiO's journey thus far in personal audio.

Magnificent in the details

The FDX features an expanded MMCX connector detachable cable designed to be easy to use, and also comes standard with interchangeable audio plugs for the 2.5/3.5/4.4mm sizes for ultimate convenience. Wrapped into a stainless steel sleeve, it achieves maximum wearing comfort. Finally, the "Born for Music" slogan is printed in our 14th Anniversary font exclusively on the FDX.

Exuding elegance with a wooden case

The FDX expresses our desire for exceptional craftsmanship in every aspect, even with the simply luxurious and elegant wooden box that the FDX comes in.
