FiiO FX17 Flagship 13 Driver IEM are FiiO's best ever earphones. The FX17 pack an incredible amount of engineering and parts quality into 2 tiny earphones. Here are some of the major features:

Titanium Housings
5 Way Crossover Design
8 Electrostatic Drivers, 4 BA drivers for mids & highs
10 mm Lithium-Magnesium Dynamic Driver
Patented S-Turbo bass venting
Silver, copper, gold blend cable
3.5mm, 4.4mm & usb-c cable plugs

To get the best sound quality possible, the FX17 features a design of one dynamic driver, four balanced armature drivers, and eight electrostatic drivers per side. A five-way crossover has been precisely tuned to balance energy distribution among the driver and ensures each unit operates in its optimal state, resulting in a grander soundstage and more natural sound.

Ergonomic Machined Titanium Housing

FiiO FX17 features a minimalist aesthetic, with a classic and natural curved cavity. The FX17’s shell ear shell cavity is made of high-density, high-strength titanium that is precisely milled from a single block and meticulously hand-polished. It is treated with vapor deposition which hardens the surface and gives it a lustrous finish, making for a beautiful display of light and shadow intertwined.

8 Electrostatic Drivers for Incredible Clarity, Detail

Electrostatic drivers have exceptional high-frequency extension easily reaching 50kHz and sense of air that gives the listener a grander soundstage. Their downside is that their sensitivity is only 99dB/mW, which is low compared to the 110dB/mW sensitivity typically found in balanced armature and dynamic drivers - leading to the 'masking effect.'

Thus, the FX17 uses 8 electrostatic units to increase sound pressure levels in order to make the electrostatic drivers more audibly perceptible as they handle the high and ultra-high frequencies above 6kHz, rather than just be for decoration.

The FIIO FX17 uses two Knowles balanced armature driver composite units that handle the mid and high-frequency sounds. Each of the composite balanced armature driver units is divided into two parts, one part responsible for mids and the other for mid-high frequency – leading to denser mids and a more transparent sound and allows them to transition seamlessly into the electrostatic drivers.

To achieve higher flagship-level vocal performance, FIIO, in collaboration with Knowles, custom-developed a 'Midrange Enhanced Balanced Armature Unit.' Acoustic vents have been added to the rear cavity of the balanced armature, which provide more sound energy reserves for the mid-frequency balanced armature unit to further tap into the driver’s advantages. The overall result is lush, mellow vocals that make the singer’s alluring voice seem as if it's truly right next to you.

Damping Vents for Improved Audio

As shown above, the rear of the cabinet has damping vents. These vents balance the pressure on the front and rear sides of the driver, improve deep bass extension and enhances clarity and transparency.

Lithium-magnesium alloy is lightweight, rigid, and has a density of 1.6g/cm³ - making it an ideal material second only to beryllium for a dynamic driver diaphragm. When reproducing high-frequency signals with rapid vibrations, the lithium-magnesium alloy diaphragm has excellent mechanical properties thanks to its high internal damping – leading to significantly reduced intrinsic frequency resonance and distortion. It allows distortion to not exceed 0.2%, for a truly clean sound.

Flagship IEM Cable Included

The FX17’s cable utilizes three different transmission materials – gold, silver, and copper - in order to take advantage of the strengths offered by the different materials. The gold, silver and copper are forged at over 1000 degrees and undergo secondary refining to form crystalline monocrystals to remove impurities and reduce transmission loss. Each of the three elements has its own advantages, which together result in significantly improved sound quality.

Included with the FX17 are three swappable audio plugs – 3.5mm single-ended, 4.4mm balanced, and Type-C connector with built-in digital decoding and DSP, allowing you to enjoy high-quality audio no matter the device you are connected to.

The Type-C swappable plug features a built-in DSP audio decoding chip that supports up to 32Bit/384kHz high-resolution PCM, and balanced output. It also supports 8-band high-precision PEQ. Through FIIO's proprietary algorithm and the FIIO Control app or web interface, the PEQ allows one to simulate or correct the headphones’ frequency response curve. Additionally, one can also export, import, share, and save EQ curves.

Includes: 22 Pairs of ear tips, 1.2m cable with 3.5mm, 4.4mm, usb-c plugs, cable change tool, magnetic cable tie, leather case, polishing cloth, serial# plaque.
