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 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.
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. 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.
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. To achieve more comfortable listening, the FH3 utilizes FiiO’s patented balanced pressure relief technology. The FH3 is carefully designed 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.
