Fosi Audio i5 Audiophile Open-Back Planar Magnetic Headphones
Overview
The Fosi Audio i5 is a full-size open-back planar-magnetic headphone designed to reveal the true character of your music. It combines precision engineering, premium materials, and refined tuning to create a sound that feels alive, balanced, and deeply musical. Every note of the Fosi i5 headphones flows with natural detail and texture, from the tight, extended bass to the smooth, shimmering highs.
At its core, the Fosi i5 open-back headphones features a custom 97 mm planar-magnetic driver with an ultra-thin nano-grade diaphragm and a high-flux magnetic array. This design from Fosi Audio captures the speed and accuracy of planar technology while maintaining a warm, natural tone. The result is effortless transparency, wide dynamic range, and a soundstage that feels spacious and three-dimensional.
Comfort is integral to the i5 headphone’s design. The dual-axis earcup system allows for precise fit and adjustment, while the memory-metal headband provides gentle, even pressure. Soft, breathable earpads ensure long listening sessions remain fatigue-free. Every element has been carefully considered to enhance the listening experience, both physically and emotionally.
The craftsmanship reflects Fosi Audio’s commitment to detail. Wooden earcups, a CNC-machined aluminium frame, and a suede-wrapped headband combine elegance with durability. The detachable 1.5 m silver-plated OFC cable offers low-resistance signal transmission and includes both 3.5 mm and 6.3 mm terminations for easy connection to amplifiers or portable players.
For Groove Central listeners, the Fosi Audio i5 open-back headphones brings high-end planar performance into an approachable form.
