FiiO FF3

Overview

The FiiO FF3 is an audiophile flathead earbud engineered with a 14.2 mm beryllium-plated dome dynamic driver, dual acoustic bass tubes, and twist-lock swappable audio plugs.

Taking inspiration from traditional Chinese double-drum musical instruments, the FF3 utilizes a 316L stainless steel shell with a unique acoustic bass cavity that funnels air smoothly to achieve deep 90 Hz bass resonance. With a lightweight Japanese Daikoku copper-clad aluminum voice coil and swappable 3.5 mm single-ended and 4.4 mm balanced plugs, it elevates earbud playback to audiophile standards.
