FIIO FX17

FIIO FX17

For exceptional sound quality, the FX17 features a hybrid driver design: one dynamic driver, four balanced armature drivers, and eight electrostatic drivers per side. A precisely tuned five-way crossover optimally distributes energy, creating a grander soundstage with natural tonality.

Electrostatic drivers offer outstanding high-frequency extension up to 50kHz and an airy soundstage but suffer from low sensitivity (99dB/mW vs. 110dB/mW for other drivers). To counteract this, the FX17 employs eight electrostatic units to enhance audibility in frequencies above 6kHz.

The FIIO FX17 integrates two Knowles balanced armature composite units for mids and highs. Each unit is split—one part for mids, the other for mid-highs—ensuring seamless transitions into the electrostatic drivers. A custom-developed ‘Midrange Enhanced Balanced Armature Unit,’ designed with Knowles, includes acoustic vents for richer vocals, making voices feel vividly present.

The dynamic driver features a lithium-magnesium alloy diaphragm, prized for its rigidity, low density (1.6g/cm³), and high internal damping. This minimizes resonance and distortion, keeping it under 0.2% for an exceptionally clean sound.

With a minimalist, curved design, the FX17’s high-density titanium shell is precision-milled and hand-polished. A vapor deposition process enhances durability and gives it a striking, lustrous finish.

The FX17’s cable blends gold, silver, and copper—each forged at over 1000°C and refined into monocrystals to reduce transmission loss and improve sound quality.

Included are three swappable audio plugs: 3.5mm single-ended, 4.4mm balanced, and a Type-C connector with built-in DSP decoding. The Type-C plug supports 32Bit/384kHz PCM, balanced output, and 8-band PEQ tuning via the FIIO Control app or web interface, allowing precise EQ customization.

Each FX17 comes with a serialized commemorative nameplate, celebrating FIIO’s 18 years of acoustic excellence.
