[Fosi Audio IM4]
Features a high-quality 10mm beryllium-coated diaphragm single dynamic driver that achieves high resolution and natural connection across three frequency bands. The dual-chamber structure combined with an N52 dual magnet circuit reproduces a natural and rich sound.
The IM4 features an open-back design, creating an open and spacious soundstage for a relaxed and fatigue-free listening experience. Instrument placement is naturally spread out, and vocals are reproduced with clarity and openness, making long listening sessions comfortable.
Designed based on a large ear shape database, it achieves a natural fit. The smooth full metal housing and lightweight design of just 7g per side provide a comfortable and unobtrusive fit all day long.
Comes with three types of eartips (balanced, bass boost, heavy bass boost) in three sizes each, and two types of nozzles (brass and aluminum alloy) for sound tuning to your preference. Additionally, it features detachable 2-pin (0.78mm) connectors, allowing you to swap cables for a customized experience.
