In-ear headphones with excellent performance in any musical scenario, exclusively designed to deliver stunning mids and highs and more robust and deep bass with minimal hiss. At the same time, it is comfortable for the human ear even during long-term wear.

Top technology 

The FH7S is equipped with the same dynamic driver as an in the FH9, the 2^nd-gen FiiO-developed large 13,6mm DKC driver. The large 13,6 mm diaphragm allows the driver to easily produce more energy for better extended bass – resulting in robust yet natural – sounding low frequencies.

The diaphragm od the FH7S dynamic driver is made of DLC (Diamond Like Carbon). Due to its highly damped nature, high rigidity, and light weight the dynamic driver is capable of rapid transient response – further adding to the sensation of dynamic bass that you will truly remember.

4 exclusively customized Knowles BA drivers

FiiO and Knowles collaborated to create the exclusively customized DFK mid-frequency BA drivers for the FH7S – with the goal of creating natural, musical vocals by greatly refining the mids. By adjusting the air permeability of the midrange drivers, it leas to a more natural, distinctive and smoother connection between bass, mids and highs. Meanwhile, vocals are more clear and more captivating with just-right richness.

The high frequencies are produced by the Knowles SWFK-31736 BA driver with its high resonant frequency. The driver contains richer highs details and airiness while also helping to further enhance the size of the soundstage which is relaxed and comfortable to listen to.

Sci-Fi armor design Pure comfort inside and out

The FH7S features a design resembling that of armor seen in sci-fi, futuristic weaponry and machinery. On the faceplate of the FH7S lie neat layers of carefully-placed holes stacked upon each other that form its semi-open design. These are combined with silver and gold trim as well as air guide nets for a meticulous balance between form and function. Finally, the FH7S still retains an overall rounded shape the perfectly fits the human ear for comfortable extended listening sessions.

The music stage simply right in front of you 

The FH7S employs FiiO’s 2^nd-gen semi-open design to accurately reproduce the soundstage of your music. This semi-open design incorporates FiiO’s system, pf balanced pressure relief between the front and rear cavities. The result is that when the drivers push air when making sound, that air encounters less resistance – resulting in a smoother vet detailed sound, natural timbre, large soundstage, and pinpoint accurate imaging.

The semi-open design also greatly reduces pressure on your eardrums, allowing you to listen longer without getting fatigued – like as if you were at the concert stage without any earphones on!

Eliminates sibilance and restore the beauty of vocals

Unique notch filter technology

Using finite element analysis and after numerous experiments, the development team created a unique notch filter for the FH7S. The notch filter precisely guides sound waves to eliminate unwanted resonances between the shell, sound tube, and ear canal to suppress undesirable sibilance – resulting in a detailed, transparent yet unfatiguing sound.

Patented S.TURBO acoustic design

The FiiO FH7S features the patented S.TURBO acoustic design, which allows for deep bass that maintains plenty of nuance and texture. Sound waves are carefully guided through a turbine-shaped tube to enhance bass frequencies so that sound liked the bating of drums are appropriately thunderous and bold.

Debuting the all-nea FiiO HS18 silicone ear tips.

The FH7S is the first to debut FiiO’s all new HS18 silicone ear tips. Thanks to the impressive efforts of the development engineers, the surface that touches the ears is only 0,4 mm thick, allowing for better comfort and seal. These new ear tips feature large opening, same as the size of the FH7S sound tube, to minimize sound barriers between the earphone and the eardrum – which reduces high frequency loss and further enhances resolution.

Cable upgraded foe a new sound experience 

The FH7S comes standard with cable consisting of 8 stands of 19 wires each – for total of 152 wires of silver-plated monocrystalline copper all individually isolated from each other. The Lit braiding of the wires means that the larger surface area leas to less resistance in the wired by minimizing the skin effect and proximity effect – lading to improved signal transmission efficiency and better resolution.

Widely compatible Twist-lock swappable audio plugs. 

New to the FH7S, compared to the FH7, are twist-lock swappable audio plugs allowing your to easily change between 3,5 single ended and 4,4 mm balanced plugs as needed. Step into the colorful words of different sounds of different audio sources.

Various sound signatures

Included with the FH7S are 3 tuning filters, each of which has its own damping characteristics and filter density for 3 distinct sounds:

RED – enhances bass, for a bold sound

WHITE – balanced sound, transparent and clear (pre-installed)

GREEN – exquisite treble, highly resolving
