FH3 

S.TURBO acoustic design

Even more performance is extracted from the beryllium-plated dynamic driver when it is combined with FiiO’s patented S.TURBO acoustic design. The longer and smoother turbine-inspired sound tubes effectively filter unwanted high frequencies, giving one deeper and harder-hitting bass.

Patent number: ZL 2018 2 1141627.9

· Physical + electronic three-way crossover

· Tube length: 41.5mm

· Effective crossover rolloff: about 32dB

The included high-purity monocrystalline silver-plated copper cable was carefully chosen for its fidelity and ability to resolve details, being noticeably better than the typical earphone cable. One’s music will sound sublime with the included cable, which brings the best out of the FH3’s drivers.

A Classic Reborn

One of FiiO’s classic earphones is getting a thorough upgrade to the next level! The FH3 utilizes an expertly tuned hybrid system of a 10mm beryllium-plated diaphragm dynamic driver + 2 Knowles BA paired with a high-purity monocrystalline silver-plated copper cable for a truly excellent high-fidelity sound.

Hi-Res Audio certified

Meticulously catered to audiophiles

Every accessory included with the FH3 was carefully chosen to enhance one’s wearing experience. 11 pairs of eartips spanning 4 different sizes and types allow one to maximize their wearing and listening comfort.

In order to achieve more comfortable listening, the FH3 utilizes FiiO’s patented balanced pressure relief technology. The FH3 is carefully designed so as to ensure that the air pressure in the front and rear chambers is balanced, thus ensuring music dynamics are not distorted and thus making for stress-free listening.

The carefully-designed internal acoustic structure as a physical frequency crossover system – ensuring that bass, mids, and treble seamlessly blend without interfering with each other for an extremely vivid experience.

Smooth as silk frequency response

Two Knowles drivers paired with a beryllium-plated dynamic driver placed near the opening of the sound tube, controlled by a physical + electronic frequency crossover system masterfully cover the entire frequency response range.

High-frequencies: the Knowles RAD-33518 driver provides extremely clear sound with well-extended yet smooth treble.

Mid-frequencies: the ED-30262 gives sweeter and fuller vocals as well as a wider soundstage.

Low-frequencies: a 10mm-beryllium-plated diaphragm dynamic driver provides explosive bass with shocking authority.

Two Knowles BA drivers for powerful sound

The 10mm beryllium-plated diaphragm dynamic driver in the FH3 was specifically chosen for its superior acoustic properties. The beryllium-plated diaphragm is not only light and thin but is also extremely rigid, allowing for thunderous yet lightning quick, responsive and dynamic bass.  

Lightning-quick, intense bass

Getting closer

Allowing clearer listening

Acoustically, placing the driver responsible to treble closer to the ear reduces unwanted treble reflections that reach one’s ears compared to a typical earphone design, ensuring minimal loss of treble detail and thus making for more pleasant listening.

Continuing the same design language as the others in the FH series of earphones, the all-new further refined water ripple design faceplate of the FH3 gives it robust strength while looking elegant. The various curves of different angles of the FH3 seamlessly blend into each other, attracting one’s eyes. And through data on thousands of people’s ears as well as going through more than 10 rounds of trials and iteration, an extremely comfortable design for the FH3 was created. Experience a truly smooth-sailing experience with the FH3 and immerse oneself in the world of music.

Smooth sailing with 3rd gen industrial design

5-axis CNC precision machining ensures that the aluminum-magnesium alloy body of the FH3 is made to tight tolerances.
