FiiO's FD3 Pro are in-ear monitors (IEMs) featuring exceptional design quality, including dynamic 12mm drivers with DLC (Diamond Like Carbon) cone in a semi-open design. They offer a magnificent quality of sound reproduction, rich and precise, capable of revealing the smallest details of your music.

A new challenger has arrived

The FD3 Pro follows in the footsteps of the other models in the FD series by using a new 12mm dynamic driver. Inside the FD3 Pro's shell is a large magnet driver with a magnetic flux of 1.5 Tesla, combined with an ultra-thin Japanese Daikoku copper-plated aluminum coil, for a powerful sound.

Carbon DLC diaphragm

The FD3 Pro benefits from the many advantages of the new FiiO dynamic driver. The cone is made of Diamond Like Carbon (DLC), which is both extremely rigid, helping to reduce unwanted distortion, and incredibly light, allowing for excellent transient response. The result is a speaker with excellent sound quality, minimal distortion and high sensitivity.

High-end acoustic prism

The acoustic prism already used in the FD5 is also integrated in the FD3. It offers many advantages, eliminating high frequency static waves, improving the diffusion of sound waves and effectively solving the delay problem caused by the propagation of sound waves in the cavity. This design results in exceptional sound quality and purity.

Design & Performances

The FD3 Pro has a simple and elegant aesthetic based on the use of curves. The unique celluloid panel is covered with a 2.5D glass film offering a transparent design. The Aluminum and Magnesium alloy also allows the FD3 Pro to remain extremely light and comfortable.

A tailor-made restitution

The sound tubes that were particularly well received on the FD5 are back on the FD3 Pro. While the outer diameter of these tubes is still the same, each model has its own inner diameter. Thus, the model with a larger inner diameter (black) will offer detailed highs, while the one with a smaller inner diameter (red) will develop deep bass. It is thus very easy to adapt the sound of the FD3 Pro to one's listening and desires.

Optimized in every detail

The attention to detail has been pushed to the design of the cable of these IEM. Detachable, it adopts MMCX connectors. The conductors, braided and 8 in number, are made of high purity monocrystalline copper and silver plated. Each conductor is made of 19 strands, for a total of 152 strands braided together to form Litz Type 2 wires. In addition, the cable features an interchangeable connector, allowing you to use either a 2.5mm jack, 3.5mm jack or 4.4mm jack, depending on your source.
