Fosi Audio, known primarily for its portable as well as desktop HiFi audio gear is here with its very first pair of in-ear monitors, introducing the Fosi Audio IM4. It’s a single dynamic driver IEM designed with a specially-developed beryllium-plated PU suspension diaphragm. The pair features a dual-magnetic, dual-cavity dynamic driver unit with high-power Neodymium N52 magnets that provide high-efficiency and low distortion in the output. Fosi has crafted the pair with high-precision 5-axis CNC machining process using 6063 series aluminum alloy material. The shells have an open-back architecture to further enhance the sound performance with a wide soundstage. With high-efficiency acoustic damping, premium dual-cavity structure, and professional tuning, the Fosi Audio IM4 promises an enchanting sound response, one that captivates its listeners every single time!!
High-Resolution Clarity with Premium Driver:-
Fosi Audio has equipped the IM4 with a high-performance dynamic driver unit. The pair houses a dual-cavity, dual-magnetic dynamic driver unit that adopts high-purity beryllium-plated dome and PU suspension diaphragm coil. It not only produces a rich sound but also provides enchanting performance with ultra-low THD+N characteristics. The driver is placed neatly in a dual-cavity structure specially optimized to achieve a pure high-fidelity sound with the IM4.
High-Strength Dual-magnetic Configuration:-
In order to produce a high-quality sound with the IM4, Fosi Audio has designed the pair with a strong dual-magnetic architecture that utilizes high-power Neodymium N52 magnets. This dual-magnetic structure produces a strong magnetic flux that ensures swift diaphragm movement. All this results in cleaner sound output with ultra-low THD+N distortion performance. It also provides high-efficiency design to the pair, it now has an output impedance of just 21Ω.
Long-Lasting Comfort, Ergonomic Design:-
Fosi Audio IM4 has got a solid build quality, the pair is crafted using high-precision 5-axis CNC machining process. It is made up of high-quality 6063 series aluminum alloy material. The pair is designed in an ergonomic shape to ensure solid comfort, we also have open-back design with grill vents available on the face panel area. With this open-back design, Fosi ensures the IM4 has a massive soundstage profile.
High-Purity Stock Cable, Solid Accessories:-
Fosi bundles the IM4 with a bunch of high-quality accessories. We have two sets of swappable tuning nozzles, one high-purity 5N OFC silver-plated stock cable, and nine-pairs of ear tips featuring three pairs each of Balanced Sound, Bass Sound, and Deep Bass Sound variants.
