Lightning-quick, intense bass

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.

Two Knowles BA drivers for powerful sound

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.

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 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.

Design for your ears

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 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 yourself in the world of music.

Hi-Res Audio certified

The FH3 earphones is certified by the Japan Audio Society to be capable of a frequency response up to 40kHz, which can fully reproduce the audio and give you a natural and life-like listening experience that truly lets you listen to the music the way the artists wanted it to sound. It brings you “Hi-Res Audio”with quality far beyond those of CDs.

MMCX cable upgrade

If you want to lisiten more different, to replace the stock cable with a higher purity one, as long as it’s with the common MMCX connectors.

With wireless Bluetooth earhooks UTWS1

With support for the aptX/AAC/SBC Bluetooth formats, the UTWS1 instantly transforms the FH3 hybrid IEM into a true wireless one.

With neckband Bluetooth cable LC-BT2

Take the hi-res music around wherever with the LC-BT2’s comfortable neckband design. Equipped with the Qualcomm CSR8675 + AK4331 DAC, this neckband cable lets one experience true hi-fi music through Bluetooth.

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

(2) enhanced bass*3 (S/M/L)

(3) enhanced vocals*3 (S/M/L)

(4) foam*2

Laboratory tests show that if the treble-producing driver is placed closer to the opening of the sound tube, 8-15 kHz frequencies are 3-4dB louder than if placed further back, for clearer overall treble.

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