Experience Music With Utmost Precision!
With the Fosi Audio i5 Open-Back Planar Magnetic Headphones you get a technically outstanding headphone featuring an enormous 97 mm planar-magnetic diaphragm, an open design for a spacious soundstage, and premium materials like walnut wood and a CNC aluminum housing. It delivers clear detail retrieval, dynamic transient response and an audiophile presentation—ideal for demanding music lovers.
Sound Experience
The huge 97 mm driver with an ultra-thin 2 µm diaphragm ensures minimal distortion, fast response and high resolution. Thanks to the open design the stage feels airy and instruments are well separated—resulting in an immersive listening experience.
Technology & Features
With an impedance of 28 Ohm and a sensitivity of 98 dB/mW the i5 can also be driven by portable devices—however, for optimal performance a more powerful amplifier (= 500 mW) is recommended to unlock its full potential. The 10 Hz to 50 kHz frequency span gives you a wide reproduction range so even subtle nuances in your recordings become audible.
Design & Comfort
The housing combines refined walnut wood with robust aluminum for a premium, audiophile look. The padding and headband design ensure a comfortable fit even during long sessions, although the weight of about 550 g should be taken into account.
