FiiO, the leader in lossless audio players, has unveiled FD5, a newly developed in-ear monitor with a large 12mm dynamic driver, utilising 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
FiiO has conducted much research and experimentation on the selection of materials for the new dynamic driver. By combining the use of Beryllium and diamond-like carbon (DLC), FiiO makes 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 minimised 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. By installing a conical device close to the front end of the driver diaphragm, FiiO 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.
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 yet transparent sound with a large soundstage and impressive dynamics.
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.
Curves of natural beauty
FiiO’s third-generation design is based on carefully-designed curves, evoking majestic mountains and wondrous waterfalls. Those curves combined with a faceplate offering two distinctly different textures form a sort of “acoustic art” that needs to be experienced in person. The stunning curved cylindrical design of the FD5 is actually a benefit for acoustics, as such a design greatly reduces unwanted resonances and reflection of sound waves within the body – allowing every last detail of your music to be faithfully reproduced.
Interchangeable parts for unlimited possibilities
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 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, allowing you to take advantage of a variety of sources.
