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 ВА paired with a high-purity monocrystalline silver-plated copper cable for a truly excellent high-fidelity sound.

Lightning-quick with 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 a 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.

Getting closer, allowing clearer listening

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


High-purity monocrystalline silver-plated copper cable

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. Your music will sound sublime with the included cable, which brings the best out of the FH3's drivers.

S.TURBO acoustic

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.

Balanced pressure relief technology and Smooth as silk frequency response

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 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.

Hi-Res Audio certified and with lots of accessories

The FH3 is certified by the Japan Audio Society to be capable of bringing you "Hi-Res Audio" with quality far beyond those of CDs.

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