Review: High quality high definition ear phone from Fiio China. Well done.
Review: Incredibly clear and very rich sounds. I bought these a few week ago. They've taken some time to find the right fittings for my ears. The black and red fittings that come with the earphones will give you more bass, plus there are small metal filters that unscrewed from the earphones, they are the red ones, best for more bass. The vital thing is that the fitting is right for your ears to achieve the bass. I also use the equaliser on my samsung phone it works very well to adjust the required sound. They are the best earphones I've bought. I used to have skullcandy but these a red a big step up. One more thing the usb c connecter I'm using is a Hi.Dac 32 bit which I would recommend for these earphones. There are no controls on these.

## Features

- [Flagship-level DLC diamond diaphragm, for an amazing, powerful sound]: The FD3 Pro headphones 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, take your breath away]: The acoustic prism so effectively used in the flagship FD5 for great sound quality is also featured in the FD3. 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.
- [Better sound with semi-open design,makes you less tiring and the sound less forced]: The semi-open 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 FD3 leading to less pressure on your eardrums.
- [2.5D film coating glass faceplate] 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 exceptionally light, making it easier and more pleasurable to carry around. And the aluminum-magnesium alloy main body is made in an industrial process combining five-axis CNC processing and hand polishing.
- [Well-equipped just for you] 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!

Excellent casque. Pas de graves « inventés » (effet boum boum). Des aiguës de très bonne qualité, scène sonore large. Très confortable et léger (nombreux embouts fournis). Excellente finition. Assurément un produit haut de gamme à un tarif raisonnable. On regrettera juste un manuel un peu succinct.
