The FiiO FF1 sits at the entry point of FiiO's FF-series flat-type earbud range, positioned below the FF3 and FF5, offering the brand's open-back earbud experience at a highly accessible price. Despite its modest cost, the FF1 incorporates the same beryllium-plated diaphragm driver technology found in more expensive earphones, making it an attractive proposition for those new to audiophile earbuds.
Beryllium-plated Driver
At the heart of the FF1 is a 14.2mm second-generation dynamic driver featuring a polyurethane diaphragm with a beryllium plating. Beryllium's exceptionally high stiffness-to-mass ratio allows the diaphragm to move quickly and accurately with minimal unwanted resonance, contributing to a clear and detailed sound across the frequency range. The driver operates across a 20Hz to 20kHz frequency response with an impedance of 45 ohms and sensitivity of 106 dB/mW.
Detachable Cable with 0.78mm 2-Pin Connector
The FF1 uses a detachable oxygen-free copper cable terminating in a 3.5mm jack, connecting to each earbud via a 0.78mm 2-pin connector. This allows the cable to be replaced or upgraded should it become damaged or if the listener wishes to experiment with alternative cables. The included cable incorporates an inline microphone and volume control remote, making the FF1 practical for use with smartphones and portable devices.
Flat-type Open Design
The FF1 uses the classic flat-type (MX500-style) earbud form factor rather than an in-ear design, sitting in the outer ear without creating a seal. This open acoustic design delivers a natural, spacious soundstage and avoids the pressure associated with in-ear monitors. At just 3.2g per earbud, the FF1 is lightweight for extended wear, and FiiO supplies a selection of foam and bass sponge covers to allow the listener to fine-tune both fit comfort and sound character.
