## Features

- [Flagship-level DLC diamond diaphragm, for an amazing, powerful sound]: The FD3 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 well-received interchangeable sound tubes also make an appearance on the FD3, The cable adopts an expanded MMCX connector for easier cable changes; the curved audio plug design makes it easier to plug into; and 4 strands of high-purity monocrystalline copper wires for a total of 120 wires make your music and vocals simply vivid.

## Questions & Answers

**Q: Can these be worn down or just over the ear?**
A: Mine arrived with what appears to a permanent coiling of the wire just before the earphones, as though they're intended to be worn over-ear. I prefer not to wear them that way. Although the coiling makes that just slightly awkward, it's still quite doable.

**Q: Can these be used with an iPhone13?**
A: Of course, but you need a lightning to aux dongle.

**Q: Does is has a mic?**
A: No mic with these earphones..

**Q: Can I use  the FD# with an Android phone?  Do I need an adapter?**
A: These headphones have a 3.5 mm TRS (phono) analogue audio connector.
if your phone does not have a 3.5 mm jack, then you will need an audio adapter (probably USB-C)
