FiiO FF5

The FiiO FF5 is an open-back earbud featuring a large 14.2 mm dynamic driver with a carbon-based diaphragm. The driver combines a PU seal with a lightweight, rigid carbon-based membrane for fast transients, improved high-frequency resolution and reduced non-linear distortion.

The open acoustic design is engineered to reduce unwanted internal reflections and standing waves. An extended acoustic bass resistance tube system helps control low-frequency resonance and provides a more expansive and defined bass response.

The FF5 comes with a detachable MMCX cable made from 4-strand, 392-conductor silver-plated monocrystalline copper. Interchangeable 3.5 mm and 4.4 mm plugs provide flexible connection options for different audio sources.

The CNC-machined aluminum alloy construction keeps the earbuds lightweight, with each earbud weighing only 3.4 g. Six pairs of anti-slip silicone rings and multiple types of sponge covers are included to help optimize fit, seal and sound.
