Newly developed flagship - Large 12 mm dynamic unit

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 diaphgram

FiiO has conducted much research and experimentation when choosing the materials for their new dynamic driver.

By combining the use of Beryllium and diamond-like carbon (DLC), they 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-emd 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.

By installing a conical device close to the front end of the driver diaphgram, 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.

Anti-standing wave and semi-open design

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.

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.

Casting a strong voice with stainless steel

The smooth, luxurious-feeling 3D embossed stainless steel faceplate represents both form adn 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, for 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.

Accessories worthy of the experience

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.
