FiiO FH5s - The in-ear headphones for the big stage

The FiiO FH5s in-ear headphones are not only an absolute eye-catcher with their elegant design, but are also technically extremely appealing and packed with clever ideas. With its "2+2" driver concept, tuning switches for sound adjustment and TRISHELL housing, FiiO once again proves that first-class engineers with a love of music were at work here. Let's go!
The highlights of the FiiO FH5s at a glance:

    2+2 drivers work in tandem - Dynamic meets Balanced Armature
    Semi-open cabinet concept - pressure in the bass; and not in the ear
    TRISHELL-Acoustic-Design - No chance for resonance and distortion
    Customisable sound - 3 switches for 8 settings
    High compatibility and flexibility - For connection and cables

2+2 drivers in tandem - Simple maths for the best sound

The FiiO FH5s uses a total of four drivers - two dynamic drivers and two balanced-armature drivers.
The dynamic drivers in detail

The woofer uses a 12-millimetre beryllium-coated driver encased in an extremely rigid yet flexible polyurethane polymer surround. The sonic advantages of beryllium are obvious. On the one hand, it is considerably lighter, but also much stronger than titanium or aluminium. With its high internal damping, beryllium minimises disturbing resonances that would distort the sound.

The woofer is driven by a powerful N52 neodymium magnet, which at 1.5 Tesla represents the current maximum magnetic force in a compact permanent magnet.

The midrange is also driven by a beryllium-coated dynamic driver, but this time with a diameter of 6 millimetres. There, the dynamic driver provides clear and realistic vocal reproduction that blends harmoniously with the rest of the sound image.
The Balanced Armature drivers in detail

Connoisseurs already know, but balanced-armature drivers are incredibly precise, responsive and accurate. Their disadvantage, however, is that they only do their job perfectly in a fairly small frequency range. Because of their compact dimensions, balanced-armature drivers are quite easy to "stack" and combine several in one pair of headphones. This is the case in the FiiO FH5s.

Here, two balanced-armature drivers share the tweeter and the super-tweeter - and they do so with the highest precision and first-class timing.

Semi-open cabinet - closed, high-resolution sound image

These headphones really pack a punch in the bass. Both in the sound image and physically. In a completely closed housing, this air pressure would have no chance to escape and would inevitably spread to the sensitive inner ear. And thus cause a certain fatigue during longer listening sessions.

But the semi-open design has other advantages. For one thing, an open, wide soundstage, since the sound can spread out realistically - similar to the original recording. Secondly, the shape of the air outlets is reminiscent of a dragon's scale, giving the FiiO FH5s a unique look.
Intricate TRISHELL design - Because every detail counts

Of course, you can make a headphone housing out of two halves of plastic and glue them together. But you can also do it like FiiO did with the FH5s and approach the subject with the greatest possible care. With a "sandwich construction" of three individual parts made of aluminium/magnesium, milled in an elaborate CNC process. The parts themselves are in turn connected to each other at three points, and together they ensure that resonances and distortions are reduced to a minimum.
Music as individual as you are - in the blink of an eye

Whether you prefer your music bass-driven, with more detail in the high frequencies or with a focus on voices, with the FiiO FH5s it's just a click away. This is done via the discreet dip switches for bass, mid-range and treble that are elegantly embedded in the headphones.

Of course, the effects can also be combined, so that a total of eight different settings are possible with the three switches. So music always sounds the way YOU like it.
Versatile and flexible - even with the connections

For the connection from the jack plug to the headphones, 120 individual conductors made of copper coated with monocrystalline silver are used, all of which together ensure a lively and crystal-clear sound. And to top it all off, the headphone cable offers not one, but three different connection options via the included interchangeable connector plugs. 2.5 mm balanced jack, 3.5 mm jack and 4.4 mm balanced jack are fitted to the cable in no time at all.

And you also have all the options in the headphones themselves, since the cable is not permanently welded, but realised in the MMCX standard. This means that you can replace the already very high-quality headphone cable with another cable of your choice with just a flick of the wrist.
Packed to the brim with accessories - everything your heart desires

FiiO FH5s accessories
Sound is individual, and so are the ear tips on the FiiO FH5s. You can choose from three different Ear Tips with bass-emphasised character, balanced character and voice-emphasised character. Each comes in sizes S, M and L. For noisy environments, there are two pairs of Bi-Flange Ear Tips (S and L) and three pairs of Foam Tips for particularly sensitive ears.

Also included: the practical FiiO HB5 storage box, a cleaning brush for cleaning after longer use and the Final MMCX ASSIST. Don't you know it? You'll learn to love it when you try to disconnect the MMCX cable from the headphones. Promise.
