  • High-Fidelity Sound: The IM4 features a premium 10mm beryllium-coated diaphragm single dynamic driver for high resolution and natural three-band transition. The driver utilizes a dual-chamber structure and N52 dual-magnet circuit to deliver natural sound
  • Spacious Soundstage: Featuring an open-back design, the IM4 delivers airy, wide-open playback for relaxed, fatigue-free listening. Instruments spread out nicely, and vocals don’t feel boxed in, making long sessions effortless
  • Ergonomic & Lightweight: The IM4 is designed using a large ear-shape database to ensure it naturally conforms to your ear. With a smooth full-metal housing and weighing just 7g per bud, it delivers a comfortable, barely-there fit for all-day listening
  • Family Design: Featuring Fosi Audio’s signature design language, the shell is crafted from full-aluminum alloy with precision CNC machining and detailed metal sand-blasting for a refined, smooth touch
  • Customizable Sound: Includes three sets of ear tips (balanced, bass, deep-bass) of three sizes, and two types of nozzles (brass, aluminium alloy) for tailored tuning. With detachable 2-Pin 0.78 mm connectors, you can swap in your preferred cables also
