FiiO FDX Gold

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.
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 extraordianry 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.
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.
The FDX is a truly a worthy piece of commemorating Fiio´s 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.
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.
