FiiO FD3

FiiO FD3 - The diamond among in-ear headphones

The FiiO FD3 is based on the dynamically constructed flagship FiiO FD5, but is reduced to the essentials - and thus much more affordable. Nevertheless, such elementary technologies as the "Diamond-Like-Carbon" diaphragm, the acoustic prism and a noble aluminium/magnesium housing are also used and together ensure outstanding sound.
The highlights of the FiiO FD3 at a glance:

    Diamond-Like Carbon - High-strength and lightweight diaphragm
    Integrated acoustic prism - For optimum time response
    Semi-open cabinet design - Deep, clean bass guaranteed
    Elegant and robust enclosure - Made of magnesium and aluminium
    Customisable sound - With two sound tubes and many accessories

12 mm driver meets Diamond-Like Carbon - Highest sound purity

For first-class sound, 12 millimetres is sometimes enough. At least when they are installed in the FiiO FD3 dynamic in-ear headphones. The diaphragm itself is made of "Diamond-Like Carbon", i.e. carbon that is almost as hard as a diamond. On the one hand, this makes the diaphragm strong and resistant to distortion, but on the other hand, it is extremely light and reacts quickly to impulses in order to reproduce the music signal faithfully.

The diaphragm is driven by a magnet with 1.5 Tesla magnetic force and a voice coil from the Japanese specialist Daikoku. This means that power is available in abundance and a clear, structured and powerful sound image is guaranteed.
Balanced sound culture - with semi-open cabinet

Of course, music should not only sound finely resolved, but also powerful. But as always, there is such a thing as too much of a good thing. The FiiO FD3 is realised as a semi-open design to always maintain just the right balance between punch and naturalness.

Not only is this more fun - especially during long listening sessions - but it also protects your sensitive ears.
Aluminium meets magnesium - in a beautiful cabinet

Although the whole is greater than the sum of its parts, every part is important. This is also true, for example, of the housing of a high-quality in-ear headphone like the FiiO FD3. Here, too - as you would expect from FiiO - nothing is left to chance, but instead relies on a precisely CNC-manufactured housing made of aluminium and magnesium.

And to make the headphones even more exciting, its housing cheeks are covered with a layer of celluloid, which is then refined with 2.5D glass. This makes it - in every sense of the word - a real highlight for the eyes and ears.
Full pipe of music - and interchangeable with a flick of the wrist

Sound is a very personal matter. And as much effort as FiiO puts into guaranteeing excellent sound, they don't know what that means for you personally. But with the two interchangeable sound tubes (i.e. tubes), you don't have to, because it's up to you.

The thicker of the two tubes (the version in red) is recommended for all lovers of lively, rather bass-emphasised sound. The thinner tube (the black version), on the other hand, provides a clear, precise sound.

It doesn't matter if you prefer one of the two styles or if you want to individualise the sound according to your musical style: Everything is possible with a few simple steps.
High quality from A to B - The headphone cable

Where FiiO has put so much effort into the headphones themselves, no compromises have been made with the headphone cable. And so the FiiO FD3 uses a high-quality connection made of monocrystalline copper with a total of 120 individual conductors.

At the same time, you are also extremely flexible thanks to the MMCX connector on the headphones themselves. No matter whether you want to change to an even higher quality cable or have to replace the cable due to a defect: The change is done in no time at all. The clever MMCX connector makes it possible.
Lots of accessories - practical and intelligent

The sound of the FiiO FD3 can already be adjusted using the two sound tubes supplied, but with the ear tips included in the scope of delivery, FiiO is taking the subject a big step further. The package includes three sets of Balanced Ear-Tips in sizes S, M and L, three sets with bass tuning and more conciseness in the vocal range. In addition, for very sensitive ears, there are two pairs of Foam Ear-Tips that adapt perfectly to the shape of your inner ear by means of body heat and ensure a perfect fit.

Also included: the practical storage box, a cleaning brush for cleaning after longer use and an MMCX assist tool. Don't you know this? You'll learn to love it when changing the MMCX cable, because it makes replacement even easier.
