Fosi Audio i5

The open-back design allows air to pass through the earcups, which creates a wider, more natural soundstage that mimics the feeling of listening to speakers in a room. Keep in mind that this design does not block outside noise and will leak sound to those around you, making them best suited for quiet environments.

With a nominal impedance of 28Ω and a sensitivity of 98dB/mW, these headphones can be driven by many devices, but they perform best with a dedicated amplifier. To get the most out of the 97mm planar drivers, we recommend using a source capable of providing at least 500mW of power.

The i5 features a dynamic V-shaped sound signature, which emphasizes the bass and treble frequencies. This tuning provides an exciting, energetic listening experience that works particularly well for genres like pop, rock, and electronic music.

No, the Fosi Audio i5 does not include a built-in microphone. They are strictly designed for high-fidelity audio playback and do not support voice communication features.

Yes, the headphones feature detachable cables with standard 3.5mm connectors. This makes it easy to replace the cable if it wears out or to upgrade to a different cable type if needed.
