Experience Music With Ultimate 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 broad 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 discerning music lovers.
Sound Experience
The massive 97 mm driver with an ultra-thin 2 µm diaphragm provides minimal distortion, fast response and high detail resolution. Thanks to the open design the stage feels airy and instruments are clearly defined — for an immersive listening experience.
Technology & Features
With an impedance of 28 Ohm and a sensitivity of 98 dB/mW the i5 can be driven by portable devices — however, for optimal performance a more powerful amplifier (= 500 mW) is recommended to unlock its full potential. The frequency span from 10 Hz to 50 kHz gives you a wide reproduction range so even subtle nuances in your recordings become audible.
Design & Comfort
The housing combines elegant walnut wood with robust aluminum — a premium look with audiophile credentials. The padding and headband design ensure comfortable wear during long sessions, although the weight of about 550 g should be taken into account.
