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 inan 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.

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.

 

Dial in your sound

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.

 

Distinguished diamond heritage

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.

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.
