Flagship Dynamic In-ear Monitors

FD5 

Beryllium-coated DLC diaphragm | Front acoustic prism

Rear volcanic field system | Semi-open acoustic design 

Interchangeable sound tubes | Interchangeable audio jacks

A “volcanic field”was added to the rear of the FD5 in order to reduce low-frequency standing waves, reduce distortion, and overall improve the diffusion of bass waves throughout the FD5. The FD5 also adopts a semi-open design, which relieves air pressure on the ear – leading to more comfortable and long listening sessions.

Anti-standing wave and semi-open design

Other diaphragms

Materials with weak rigidity are slower to respond to voice coil movements and produce irregular ripple-like movements, causing distortion 

FD5 diaphragm

Because of its use of rigid DLC material, the diaphragm is more responsive to voice coil movements for less distortion and more accurate reproduction of sound.

acoustic design breakthroughs

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.

Curves of natural beauty

A sound you actually want

Compared with a multiple-driver IEM, in the FD5 there is only one point from which the sound is produced from a single driver – making for more accurate sound positioning. The flagship-grade dynamic driver and carefully tuned acoustic design also combine to make the FD5 sound wonderfully pleasant to most people's preferences – a relaxed, natural

Casting a strong voice with stainless steel

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.

Large 12mm dynamic unit

Newly developed flagship driver

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.

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.

Beryllium-coated surround + DLC diaphragm

By installing a conical device close to the front end of the driver diaphragm, we can precisely control how the sound waves travel in the sound tube – bringing benefits such as eliminating high frequency standing waves and enhancing overall sound wave diffusion.

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.

Find something that suits you

Great sound comes from a great fit, which is why the FD5 comes with interchangeable sound tubes in small and large sizes to best fit your ear. The large sound tube is balanced, while the small sound tube presents a lively, more bass-focused sound. 

*The small sound tube should be used with the triple-flange ear tips, for deeper insertion and better sound quality.

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.

Material: High-purity monocrystalline silver-plated copper

Wire diameter: Single wire 0.08mm, strand 24AWG, entire cable 18AWG

Wire count: 19 per strand, 8 strands, 152 total wires

Structure: Litz Type2, each wire is individually insulated

Interchangeable parts for unlimited possibilities

*Interchangeable audio jack is officially licensed from the patent by FABRILOUS

The FD5 is Hi-Res Audio certified, a testament to its highly-detailed, yet rich and lifelike sound.

Hi-Res Audio certified

Even the accessories have been thoughtfully considered for the FD5. The included HB5 storage case dutifully protects your earphones, while the included MMCX clips greatly facilitates detaching the MMCX cables.
