FiiO has always spared no effort in creating their flagship products. In the FD5 is a newly developed, large 12mm dynamic driver utilizing N52 magnets with a high magnetic flux of 1.5 Tesla - for extremely robust bass and excellent high frequency resolution.

Beryllium-coated surround + DLC diaphragm
We have conducted much research and experimentation when choosing the materials for our new dynamic driver. By combining the use of Beryllium and diamond-like carbon (DLC), we make full use of the physical rigidity and flexibility properties of the materials to reduce unneeded vibration and appropriately damp sound for improved quality. Overall, the frequency response is balanced and distortion is minimized at all frequency ranges.

High-end audio inspired acoustic prism
In order to address the issues that come with the time delay between different sound waves, an acoustic prism system was specifically developed for the FD5. This was inspired by similar technology used for adjusting tweeters in well-known high-end audio products.

Curves of natural beauty
FiiO's third generation design is based on carefully-designed curves, evoking majestic mountains and wonderous waterfalls. These curves combined with a faceplate offering two distinctly different textures form a sort of “acoustic art” that needs to be experienced in person. The smooth, luxurious-feeling 3D embossed stainless steel faceplate represents both form and function – while looking striking, the robust stainless steel also reduces the harmonic distortion of sound inside the FD5. The faceplate provides a striking contrast against the chrome finish of the rest of the FD5 as well.

Interchangeable parts for unlimited possibilities
The included cable is an expanded MMCX design with 8 strands of monocrystalline silver-plated copper cable that perfectly and faithfully reproduces your music. The cable also features interchangeable audio plugs for 2.5mm/3.5mm/4.4mm, you to take advantage of a variety of sources.
