Open-Back Planar Magnetic Headphones Jack 4.4mm 28 ohm 98dB 10Hz-50kHz

The Fosi Audio I5 Offline Version is an open-air Planar Magnetic headphone. They feature a diaphragm no less than 97mm in diameter, offering a wide soundstage. Each driver incorporates a double array of balanced Neodymium N50 magnets for precise, stable diaphragm vibration. This greatly reduces any form of distortion for a clear, authentic sound reproduction. The earcup structure is made of CNC-machined aluminum, combining robustness and pleasing aesthetics. Silky pads and a leather headband complete the structure, providing optimum wearing comfort. With its 28 ohm impedance and 98dB sensitivity, the I5 is relatively easy to drive, although it will require a good amplifier capable of delivering over 250-500mW of power. In addition, its dynamic range from 10Hz to 50kHz offers the most immersive listening experience. The package is completed by a detachable audiophile-quality balanced 4.4mm jack cable.
