Electrostatic IEMs are no longer a novelty in the high-end IEM landscape, but the FX15 is FiO’s first foray into producing such a product. When developing the FX15, the FiOR&D team researched how best to utilize electrostatic drivers. Due to the low sensitivity of such drivers, special care must be taken to ensure they are not overpowered by the other dynamic and BA drivers in use. Otherwise, listeners will not be fully able to experience the unique sound that electrostatic drivers bring to the table. “Dare to be at the top” is an important part of FiO’s corporate culture.
Fio does not merely use new techniques or materials simply to attract attention with new gimmicks but rather chooses to fully research new methods to come up with products that fully utilize the potential of such new approaches. In a sense, “being slow makes you end up being faster.” The development of the FX15 embraces this ethos as the FiO R&D team carefully made sure that dynamic, balanced armatures, and electrostatic drivers worked together in harmony to fully bring out the best of the latter before choosing to release this new IEM.
Electrostatic drivers are known for their high-frequency
detail reproduction, but such drivers are usually used in
extremely expensive IEMs out of reach of most
audiophiles. The FiO FX15 employs 4 electrostatic
drivers per channel that not only provide exceptionally
ultra-high frequency extension[1], but are exceptionally
quick and able to reproduce every last detail in your
music, giving the listener a taste of true high-end audio.
We have added a switch that specifically turns on and off the
electrostatic drivers, allowing the listener to instantly AB between
having and not having the drivers. Easily and instantly experience
the impact of electrostatic drivers on your music.
The FX15 tribrid IEM features the patent S. Turbo acoustic design[2] designed to
maximize bass performance. At the heart of the S. Turbo design is a lengthened
low-frequency sound tube that effectively filters high-frequencies produced by the
dynamic driver, so that the sound of the bass dynamic driver and mid-to-treble
balanced armature drivers are smoothly connected and do not interfere with each
other for optimal sound quality.
The FX15 comes with a high-purity silver cable of 224 total
wires separated into 8 strands of 28 wires each. Each wire is
independently insulated and the cable features Litz braiding.
The outer sheath is made of environmentally friendly TPU,
not only allowing the cable to look more vivid and
transparent, but also better protecting the cable against
yellowing and hardening.
FiO not only considers the shape and materials used for its IEMs, but
also whether they are user-friendly. Through repeated
measurements and wearing tests, Fio engineers optimized the
the shape of the FX15, which is a triangle not only feels comfortable
to wear but also securely stay in the listener’s ear – for an ideal
balance of comfort and stability.
The FX15 is a highly resolving IM that is more than capable of
reproducing sound frequencies above 15kHz. To visually represent its
capabilities, the FX15 features a design that embodies the ethos of
“sound and form” working together in harmony. The golden ginkgo
leaves imposed on the FX15 shell cover serve as a visual reminder of
its brilliant and vivid sound that fully allows the listener to discover the
stories embedded within the music.
FiO cooperated with HeyGears to create a shell that features both
excellent comfort and durability, to let the listener fully enjoy the
highly resolving electrostatic IM without worry. The FX15’s shell is
made using the advanced DLP-3D printing method with printing
accuracy down to 0.0375mm, ensuring that each FX15 shell is
accurately moulded to ensure highly consistent sound between every
unit made. In addition, the FX15’s shell is made of photosensitive
resin, which features high impact resistance, providing robust
protection for the electrostatic and balanced armature drivers.
The FX15 adopts the proven Knowles ED-29689 balanced armature driver to handle the mids and lower treble frequency ranges, due to the driver’s smooth, lush, yet detailed sound. In addition, the R&D team reduced the sensitivity of this BA driver through the shell design and other methods. This ensures that the BA and electrostatic drivers output their respective frequency ranges without interference from each other – resulting in the two drivers working together in harmony with a smooth overall frequency response curve.
