FiiO FH3 Hi-Res In-Ear Earphones — 3 Drivers (1 Beryllium-Plated Dynamic + 2 Knowles BA) — High-Fidelity Bass for Smartphone/PC/Tablet

Precision-tuned 3-driver in-ear monitors delivering detailed, bass-rich audio. The FH3 pairs a beryllium-plated dynamic driver with two Knowles balanced-armature units and uses a physical + electronic frequency crossover system to cover the full audible range. The dynamic driver is positioned near the opening of the sound tube for controlled low-end impact and coherent integration with the BAs. High frequencies are handled by the Knowles RAD-33518 driver, offering clear, extended yet smooth treble. Midrange duties are performed by the ED-30262, producing fuller, sweeter vocals and a more spacious soundstage. Included is a high-purity monocrystalline silver-plated copper cable, with 4 strands of 96 wires, chosen for superior resolution and fidelity compared with standard earphone leads. Built for comfort and long listening sessions, the shells are CNC-machined from aerospace-grade aluminum-magnesium alloy using 5-axis precision equipment. The FH3 continues the ergonomic approach of the FH series, developed from ear-shape data gathered from thousands of users to achieve a comfortable fit. International products may ship from abroad and could differ from local versions in fit, age ratings, labeling, or language of the instructions.
