FiiO has come up with a brand new set of High-resolution earbuds, the FiiO FF3. Featuring a unique drum-shaped design, the FF3 brings a powerful sound performance with enhanced bass response. FiiO has equipped the FF3 with a large and potent 14.2mm dynamic driver unit. Built with high-quality material such as a beryllium-plated dome and PU gasket diaphragm, the dynamic driver here is tuned to deliver an impressive sound performance. FiiO FF3 comes as a complete package with three different types of foam covers (bass-enhancing, balanced and treble-focused) and a high-purity silver-plated monocrystalline copper cable with interchangeable termination plugs.

Powerful & Unique Cavity Design

Based on the drum musical instrument, an all-new bass cavity design was made especially for the FF3. The cavity was specially designed to full harness and utilize resonance to more effectively bring out the texture of bass notes as well as accurately reproduce the timbre of music with surprising agility.

Bass Enhancing Acoustic Flute Design

FiiO made full use of the internal space of the FF3’s housing to fit a bass-enhancing acoustic tube within. This tube extends the airflow path, increases air damping, and improves sound damping to lower the resonance point of the earphones for amazing sound performance. This allows the FF3 to reproduce frequencies as low as 90Hz under normal open wearing (without the use of sponge cover).and have an effective frequency range down to 42.5Hz for truly deep earbud bass.

Get The Best Sound With A Large Dynamic Driver

FiiO has designed a large 14.2mm dynamic driver for the FF3. This driver uses high-quality components like a Beryllium-plated dome and PU gasket structure. With professional tuning adjustments, FF3 achieves an impressive sound performance with deep hitting soulful bass response, excellent treble energy, natural timbre, and a spacious soundstage. FiiO has adjusted the tuning on the FF3 to provide exceptional clarity for vocals and instruments.

Get The Best Performance With High-Purity Cable

FiiO FF3 comes packed with a high-purity silver-plated monocrystalline copper cable that uses 152 wire cores. Silver-plating improves the treble resolution while producing a sibilance-free response. The sheath of the cable is made of German TPU – allowing the cable to be not only resistant to yellowing and hardening, but also for increased cable flexibility so that its more comfortable to wear. The cable also comes with an all-aluminium twist-lock swappable plug design, including 3.5mm and 4.4mm termination plug connectors.
