FiiO Unveils FD7 – Pure Beryllium Diaphragm Dynamic Driver IEM

FiiO has announced the new FD7 in Singapore. The new in-ear monitor (IEM) features a pure Beryllium Diaphragm Dynamic Driver, front acoustic prism, twist-lock interchangeable audio plugs, and an exclusive color scheme. FD7 is the latest addition to the FiiO FD family and the new flagship model for FiiO, an upgraded version from the popular FD5. 

The new flagship features a 12mm pure beryllium diaphragm dynamic driver. As beryllium is 4 times more rigid than steel and weighs 1/4 as much as titanium, it possesses 3 times the transient performance compared to titanium drivers. Thanks to that, the FD7 is able to produce unmatched powerful sound with rich audio details at lightning speed.

The FD7 also sees tech capabilities brought over from the previous FD models. Close to the pure beryllium driver in the FD7 is an acoustic prism system that addresses the time delay between different sound waves. The front acoustic prism effectively changes and controls the way sound travels through the FD7, enhancing the high-frequency waves and ensuring that the audio phases are accurate.

Another tech from the well-loved FD5 is the ingenious volcanic field system developed by FiiO. The volcanic field system takes advantage of how sound waves work to improve its sound noticeably. The volcanic field reduces standing waves and distortion, and overall improves the diffusion of bass waves in the FD7. 

The FD7 also comes with a high-purity monocrystalline pure silver cable – a 4 wires braid with a total of 224 strands, wrapped in medical-grade TPU sheath. The TPU cable shell helps against yellowing after long-term use and against stiffening when in low-temperature environments. The cable also features 3 twist-lock interchangeable audio plugs for sizes 2.5mm/3.5mm/4.4mm, allowing you to take advantage of a variety of sources, for convenience.

The FD7 also comes equipped with three pairs of interchangeable sound tubes, each with different inner diameter for different sounds. The red tube boosts bass, the black tube presents detailed treble, while the green tube achieves deeper insertion in-ear canals when working with bi-flange or triple-flange ear tips for rich ultra-high audio details. The black tubes come pre-installed on the earphone units. Other tubes are included in the package.

Not just rich in audio technicalities, the FD7 is meticulously engineered with the comfort of its users in mind. The cable of the FD7 was designed with expanded stainless steel MMCX connectors which went through many ergonomic iterations and improvements in order to achieve maximum wearing comfort.

In addition, the semi-open design on the FiiO FD7 effectively relieves the pressure on the ears for a more comfortable listening experience. 

The colour scheme of black and gold is exclusive to the FiiO FD7. The colour combination hints at its grand audio prowess, evoking ancient Chinese landscape paintings with a river of gold flanked by vast black mountains created through bold ink brushstrokes. 

FiiO FD7 retails for S$949.00 (including GST) and is available immediately at AV One, Headphones.SG, Stereo Electronics and Treoo.
