FEATURING FLAGSHIP-LEVEL DYNAMIC DRIVER WITH 1.5 TESLA MAGNETIC FLUX AND JAPANESE VOICE COIL
FiiO FD3 Pro continues in the direction of its FD line siblings in using the flagship-grade 12mm dynamic driver. The inside of the FD3 Pro shell is embedded with a driver with a robust magnet of 1.5 Tesla magnetic flux, paired with an ultra-fine copper-clad aluminium Japanese Daikoku voice coil for accurate sound reproduction.



ULTRA-MODERN DLC DIAPHRAGM AND ACOUSTIC PRISM SYSTEM FOR LOW DISTORTION AND SUPERIOR CLARITY
Flag-ship grade components have been used in the design of the FiiO FD3 Pro. The diaphragm is made of diamond-like carbon (DLC) which is rigid and surprisingly light. This design decision makes the FD3 Pro comfortable to wear and also reduce unwanted distortion having a tremendous transient response. The FD3 Pro’s are further enhanced with the acoustic prism system which brings numerous benefits such as eliminating high frequency standing waves, enhancing overall sound wave diffusion and even effectively solving the problem of time delay caused by sound wave propagation path in the cavity. This all leads to amazing sound quality.



COMES WITH EXCLUSIVE HIGH PURITY LITZ CABLE AND HI-RES AUDIO CERTIFICATION
FiiO FD3 Pro comes with a carefully engineered cable that enhances the listening experience. The FD3 Pro comes with an exclusive cable made of high purity monocrystalline silver-plated copper cable with 8 strands of 19 wires each for a total of 152 wires braided together in Litz type 2 style. In addition, the cable features blue (left) and red (right) markings for convenience as well as interchangeable audio plugs, allowing you to switch between 2.5/3.5/4.4mm plugs depending on your source. The cable features an MMCX connector for connectivity. This reproduces music vividly and with superior clarity. The FD3 Pro is a Hi-Res Audio certified earphone and is capable of reproducing delicate details.


INDUSTRIAL GRADE ALUMINUM-MAGNESIUM ALLOY BODY FUSED WITH A SEMI-OPEN DESIGN
High-quality craftsmanship is the primary goal at FiiO and this is reflected in the FD3 Pro unmistakably. The main body is made of aluminium-magnesium alloy in an industrial process combining five-axis CNC processing and hand polishing. This makes the body durable and super elegant to look at. The FD3 Pro features a semi-open design that is based on the company’s patented technology for balanced air pressure. This semi-open design provides a natural sound and also effectively protects your hearing by balancing air pressure within the body and leads to less pressure on your eardrums. This enhances the listening experience tenfold, making the sound less forced.

PERFECT BALANCE BETWEEN FORM AND FUNCTION
The look of the FiiO FD3 Pro is based on the theme of curves and is simple yet has a beautiful appearance. This is visible in the unique celluloid panel which is covered with 2.5D film coating glass for a Pure transparent look. The FD3 Pro also features interchangeable sound tubes for customising the frequency response of the earphone. How this works is, while the outer diameter of the sound tubes is the same, the inner diameter differs for each sound tube. The large inner diameter tube (black) produces detailed treble, and the small inner diameter tube (red) gives robustness. This is a truly unique approach and is the perfect balance of form and function.

1. The small hole in the front cavity is used to relieve air pressure. It can help to moderate pressures that happen to the ear canal when putting the FD3 Pro inside the ears. If the front hole is blocked, it would enhance the bass performance. However, hearing fatigue would also be caused easily due to increasing pressures in the ear canal.
2. The diaphragm of the FD3 Pro is made of Diamond-Like Carbon (DLC). Therefore, if the front pressure-relief hole is blocked, it will cause unneeded distortion due to slight transformation of the diaphragm when it is vibrating.
[Semi-open acoustic design] The semi-open acoustic design of the FD3 based on FiiO's patented technology for balanced air pressure within brings several advantages. Not only does such a design lead to more natural sound, but it also effectively protects your hearing by balancing air pressure within the cavity, leading to less pressure on your eardrums. This makes your listening experience less tiring and the sound less forced.
[Front acoustic prism]
The acoustic prism so effectively used in the flagship FD5 for great sound quality is also featured in the FD3 Pro. Like with the FD5, the acoustic prism system brings numerous benefits such as eliminating high frequency standing waves, enhancing overall sound wave diffusion, and even effectively solving the problem of time delay caused by sound wave propagation path in the cavity. This all leads to marvelous sound quality that will surely take your breath away.
