Fiio FD3 Pro Single Dynamic In Ear Monitor Semi Open Design with Interchangeable Sound Tube

The FD3 Pro follows in the footsteps of its FD line siblings in using a newly designed 12mm flagship-level dynamic driver.Inside the 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. The 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. 

The acoustic prism so effectively used in the flagship FD5 for great sound quality is also featured in the FD3 Pro. FD3 Pro 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 Pro based on FiiO's technology for balanced air pressure within brings several advantages. It also effectively protects your hearing by balancing air pressure within the FD3 Pro leading to less pressure on your eardrums. This makes your listening experience less tiring and the sound less forced. 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.

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.
