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 centre of attention with the brilliant shimmering of the gold FDX in your ears.

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 extraordinary lightweight, being 4x more rigid than steel and ¼ 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 diamonds inlay
The FDX rear panel is inlaid with a total of 60 imitation diamonds. The Cupid hearts cut into the crystals elegantly combined with the golden panel for a brilliant and sensational appearance, not unlike that of a centre 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 yellowing after long-term use and against stiffening when in low-temperature environments.
