Experience the ultimate IEM - the FiiO FF3 in-ear monitors. It features a beryllium-plated dome dynamic driver with a 14.2mm PU gasket diaphragm for a spectacular audio experience. The high quality materials improve the stellar sound even more.

Superior Driver for Spectacular Sound
After multiple tests, a beryllium-plated dome and 14.2mm PU gasket diaphragm were chosen for the dynamic driver for a clean and natural sound. The lightweight diaphragm is highly rigid which reduces unwanted vibration and distortion. PU allows more detailed and textured bass with lush vocals and improved treble up to 17kHz. The wider frequency range ensures a wider soundstage.

Enjoy Better Resolution
The FiiO FF3 features an ultra-fine copper-clad Daikoku voice coil with a 0.033mm diameter. The lightweight composition reduces the overall weight of the dynamic driver allowing it to move faster and further improve treble resolution.

All About that Bass
The new bass cavity design has been inspired by a drum musical instrument to harness and add texture to the bass using resonances to accurately reproduce the timbre with surprising agility. A bass-enhancing acoustic tube extends the airflow path with better air and sound damping to lower the IEM’s resonance point for an amazing audio performance. This reproduces frequencies as low as 90Hz under normal open wearing and 42.5Hz for truly deep earbud bass.

Housings that Captivate
Just like other FiiO IEMs, the FF3 displays fine craftsmanship and high-quality materials. The stainless steel housing is polished and PVD electroplated, flaunting either an Elegant Black or Cosmic Silver finish. A highly permeable tempered glass faceplate enhances its appearance offering a unique look at every angle.

Cables that Connect
The high-purity silver-plated monocrystalline copper cable consists of 152 wires for better treble resolution with unwanted sibilance. The sheath of the cable is made of German TPU, adding flexibility lowering microphonics and resisting yellowing and hardening. An aluminium twist-lock swappable plug design makes switching between 3.5mm and 4.4 mm plugs easy.

Choose Your Audio Experience
The FF3 comes with 3 types of sponge covers for different audio profiles – bass-enhancing, balanced, and transparent treble-focused. The treble-focused sponge cover offers better resolution. Each housing is marked with a Blue and Red point for easy identification.
