Fosi Audio IM4

Dual magnet and dual chamber for HiFi sound: Experience audiophile-level clarity. These IEM earphones feature N52 dual magnets for powerful control and a dual-chamber design for balanced sound. The 10 mm beryllium driver delivers a wide soundstage with clear, detailed audio.

Balanced and fatigue-free tuning: The open design and acoustically dampened wool reduce resonance and harshness, producing a relaxed, expansive sound. The HiFi earbuds are expertly tuned for balanced bass, midrange, and treble, making them ideal for audiophiles.

Ergonomic and lightweight comfort: Designed for all-day wear. The housing has a smooth, hypoallergenic metallic finish that feels pleasant to the touch. At just 7 grams per earbud, these are among the most comfortable in-ear monitors for extended use.

Premium CNC aluminum: Exceptional build quality and minimalist aesthetics. The housing is precision-machined from a solid aluminum block. The unique orange metal grille and logo give the IEMs a distinctive appearance, combining style and substance.

Customizable sound and detachable cable: Tailor your audio experience. The IEM set includes 3 types of ear tips (bass, deep bass, balanced) and two sound nozzles (brass, aluminum) for precise tuning of bass and treble. Comes with a 2-pin 0.78 mm detachable cable supporting 3.5 mm and 4.4 mm connections.
