FF5 carbon-based dynamic driver in-ear earphone

The FiiO FF5 uses a specially developed 14.2 mm dynamic driver with a PU gasket and carbon-based diaphragm plus extended bass acoustic resistance pipes. It delivers a live soundstage with sufficient sub-bass, lush vocals and clear treble. The package includes a standard four-stranded 392-wire silver-plated monocrystalline copper cable to reduce skin effect and improve treble resolution.

Check your source and fit before ordering

Ensure your playback device offers a 3.5 mm or 4.4 mm headphone output to match the supplied MMCX cable terminations. Verify that an in-ear form factor suits your comfort preferences and that you can achieve a proper seal with the included tips. The detachable MMCX connectors allow cable replacement but require careful alignment when swapping.

Thermals noise and power draw in normal use

Passive in-ear monitors generate no heat and produce no audible self-noise during listening. They draw negligible power from the source device, so battery drain on portable players is minimal. The aluminium shells remain at ambient temperature even during extended sessions.

Questions about this item

What accessories are included in the box and what must be purchased separately?

How do I choose between the 3.5mm and 4.4mm plugs supplied with the cable?

The large 14.2mm driver with a PU-gasket carbon-based diaphragm and extended bass acoustic resistance pipes produces a live soundstage with sufficient sub-bass, lush vocals and clear treble for music playback.
