Fosi Audio i5 – Headphones with a Diaphragm Made Using Nanotechnology

Fosi Audio i5 are planar on-ear headphones with an ultra-thin diaphragm made using nanotechnology, a powerful magnetic system and, according to the company, realistic and immersive sound. Fosi Audio i5 provides the highest sound pressure of up to 120 dB and operates in the frequency range of 10 Hz - 50 kHz. The sensitivity of the model is 98 dB, the nominal impedance is 28 ohms, and the recommended amplification power is from 500 mW.

The Fosi Audio i5 headphones use a large 97 mm diaphragm with sputtering technology. Ergonomic ear pads made of leather and fabric with the ability to adjust the angle of inclination vertically and horizontally guarantee a comfortable fit and no fatigue even with prolonged listening.

The use of natural walnut wood in the production of the headphone housings gives uniqueness, and all aluminum parts are processed with precision on CNC machines. Fosi Audio i5 planar headphones are equipped with a detachable cable with a 3.5 mm mini-jack plug, which allows you to use both standard cables and cables with a balanced Pentaconn 4.4 mm connector.
