SINGAPORE – FiiO, a company that has pioneered the field of high-resolution lossless audio players, has just released the FiiO FH3 Hybrid In-Ear Monitor in Singapore.

A Classic Reborn

FiiO’s FH3 is a significant update from the old F9, as it follows in the footsteps of the wildly successful F9 and F9 Pro, while maintaining the F9 series’ hallmark sound quality and ergonomic design. The new FiiO FH3 has a high-purity mono-crystalline silver-plated copper wire and a hybrid system consisting of a 10mm beryllium-plated diaphragm dynamic driver and 2 Knowles Balanced Armature (BA) drivers.

Triple drivers for clarity and depth

The FH3 features a dynamic driver with a 10mm beryllium-plated diaphragm for improved sound quality. The light and thin beryllium-plated diaphragm is also four times as stiff as steel, resulting in a powerful bass. The FH3’s versatility comes from its pairing of two Knowles BA drivers and a frequency crossover mechanism that is regulated electronically and mechanically. The high frequencies are well-extended and smooth, the midrange is sweeter and broader, and the low frequencies are explosive, providing music lovers with crystal-clear sound.

Optimised results with S.TURBO Acoustic Design

Along with its beryllium-plated dynamic driver, the FH3 has FiiO’s proprietary acoustic design, the S.TURBO. Listeners will experience a deeper and more powerful bass thanks to the turbine-inspired sound tubes’ larger length and smoother interior.

Not just aesthetics

FiiO is committed to the FH family’s design ethos by continuing its pursuit of fine craftsmanship in the elimination of unnecessary resonance and distortion for the purest sound.

The FH3 is machined using five axes of precision, and it is constructed from an aluminum-magnesium alloy suitable for use in aircraft applications. The alloy shell requires 23 tool bits and 4,340 final milling cuts to obtain the desired shape. It takes its cue from the natural world, with a faceplate that is reminiscent of the hypnotic waves you see in the ocean.

Other highlights of the new FiiO FH3 includes:

  • 4 strands of 96 wires high-purity monocrystalline silver-plated copper cable: The included cables are 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.
  • Get addicted to stress-free listening: In order to achieve more comfortable listening, the FH3 utilises FiiO’s patented balanced pressure relief technology to ensure that the air pressure in the front and rear chambers is balanced, allowing for the music dynamics to not be distorted, and thus making for stress-free listening.
  • Smooth as silk frequency response: 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.
  • More ways to listen: The FH3 offers flexibility in enjoying your music the way you like it. It is compatible with MMCX connectors, and allows you to transform the FH3 to a wireless, or neckband variation, compatible with wireless Bluetooth ear hooks UTWS1, supporting aptX/AAC/SBC Bluetooth formats, and neckband Bluetooth cable LC-BT2
  • Meticulously catered to audiophiles: The FH3 is Hi-Res Audio certified and every accessory included is carefully chosen to enhance one’s wearing experience. There are 11 pairs of eartips spanning 4 different sizes and types, allowing the listener to maximise their wearing and listening comfort.
