A new challenger has arrived
The FD3/FD3 Pro follows in the footsteps of its FD line siblings in using a newly designed 12mm flagship-level dynamic driver. Inside the FD3/FD3 Pro's striking shell lies a driver with a robust magnet of 1.5 Tesla magnetic flux paired with an ultra-fine copper-clad aluminum Japanese Daikoku voice coil for an amazing, powerful sound.

Distinguished diamond heritage
The FD3/FD3 Pro benefits from the numerous advantages of FiiO's new dynamic driver. The diaphragm is made of Diamond-Like Carbon(DLC) which is both impressively rigid and helps to reduce unneeded distortion yet also surprisingly light, allowing the driver to have excellent transient response. The result is a driver with excellent sound quality and minimal distortion with the added bonus of being ultra-sensitive.
Flagship-grade acoustic prism
The acoustic prism so effectively used in the flagship FD5 for great sound quality is also featured in the FD3/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.
Better sound with semi-open design
The semi-open design of the FD3/FD3 Pro 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 FD3/FD3 Pro leading to less pressure on your eardrums. This makes your listening experience less tiring and the sound less forced.
Form and function arc into one
The FD3/FD3 Pro has a simple, yet beautiful appearance based on the theme of curves. The unique celluloid panel is covered with 2.5D film coating glass for a pure yet fresh transparent look. And the aluminum-magnesium alloy of the body makes the FD3/FD3 Pro exceptionally light, making it easier and more pleasurable to carry around.
Always striving for perfection
FiiO has always been concerning about exceptional high quality craftsmanship, and the FD3/FD3 Pro is no exception to this rule. The aluminum-magnesium alloy main body is made in an industrial process combining five-axis CNC processing and hand polishing. The pin-point precision of machinery and the delicate touch only possible by human hands come together to create a phenomenal piece in the FD3/FD3 Pro.
Dial in your sound
The well-received interchangeable sound tubes on the FD5 that so well symbolize it as a flagship also make an appearance on the FD3/FD3 Pro. While the outer diameter of the sound tubes is the same, the inner diameter differs for each sound tube. Pick the large inner diameter tube (black) for detailed treble, and choose the small inner diameter tube (red) for robust bass. Let your inner perfectionist be happy with the ability to dial in your sound perfectly.
Well-equipped from start to finish
Each of the FD3 cable's numerous features has been carefully designed to truly enhance your experience. The cable adopts an expanded MMCX connector for easier cable changes; the curved audio plug design makes it easier to plug into.
Next level FD3 Pro exclusive cable
The FD3 Pro comes with an exclusive cable made of high-purity monocrystalline silver-plated copper, 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 left blue and right red markings for convenience as well as interchange audio plugs, allowing you to freely switch between 2.5/3.5/4.4mm plugs depending on your source. With this cable, every music note has never been clearer!
