  • 6 Knowles BA | DLP 3D printing |
  • 80.6mm ultra-long sound tube
  • 4-way electronic crossover
  • 3 sound adjustment switches
  • 8-strand monocrystalline silver-plated copper cable


A whole new level of sound - 6 Knowles BA driver custom setup
The 6 Knowles BA drivers per ear, together with the carefully-designed 4-way crossover and low-frequency ultra-long sound tube, completely covers the entire audible frequency range with a sound that will take your breath away.

  • Higher/ultra-high frequencies:
    handled by the SWFK-31736 driver that blends extreme resolution with rich sound
  • Mid-frequencies:
    EJ-33877 custom driver collaboratively created by FiiO and Knowles, with powerful mids that give lush vocals
  • Lower frequencies:
    HODVTEC-31618 driver, with 2 woofers that produce dynamic and authoritative bass


More lifelike sound than ever - Custom Knowles EJ BA driver
The FA9 marks the first time FiiO has employed Knowles EJ balanced armature drivers, commonly used among high-end IEMs. FiiO and Knowles collaborated to come up with the custom EJ-33877 driver for use in the FA9 for excellent mid-frequency performance with hauntingly realistic vocals.

80.6mm ultra-long sound tube - Specially-designed acoustic filter
In order to achieve the purest sound performance and to ensure the multiple drivers do not interfere with each other, the FA9 employs a specially-designed, ultra-long sound tube 80.6mm in length. The sound tube acts as a low-pass filter that effectively filters out unneeded extra mids and highs from the drivers to ensure a seamless frequency response. The sound tube also ensures the mid-bass is smooth and clean while enhances bass texture in general.

Make it truly yours - 3 sound adjustment switches / 8 possible sounds
The FA9's use of electronic crossover technology allows you to tune the sound to exactly the way you want with 3 sound adjustment switches. The impedance, bass, mids and treble adjustment depends on what music you are listening or what your preferences are!

S1 switch on: lower impedance and higher sensitivity, making the FA9 easier to drive
S1 switch off: higher impedance for a more clean and natural sound, with a darker background and lower audible noise from the source
S2 switch on: treble boost, perfect for those seeking more highs and for rock music
S2 switch off: treble normal for more balanced tuning, suitable for most types of music
S3 switch on: reduced bass and increased mids, useful when listening to human voices and musical instruments
S3 switch off: increased bass and reduced mids, good when listening to classical and orchestral music

Four-way crossover - Igniting a fire within your heart
The four-way crossover design has been applied so that each driver works perfectly in harmony with each other for seamlessly coherent low, middle, high, and ultra-high frequencies. With dynamic bass, crystal clear yet lush vocals, and extremely detailed yet pleasant treble, the FA9 will get you excited about your music again.

The beauty of unprecedented precision - 4th generation DLP 3D printing
Unlike most other 3D printed headphones, the FA9's entire shell is created through DLP 3D printing technology. Now in its 4th generation, the printing accuracy, efficiency, and curing uniformity have been significantly improved from the past iterations of DLP 3D printing. This allows the FA9 to have an extremely precise and robust structure that is fully optimized for audio that is difficult to achieve with traditional manufacturing methods.

Beautiful at any angle - Diamond-cut faceplate / Seamless translucent shell
An all-new diamond-cut faceplate is integrated perfectly with the seamless translucent-black resin shell for a gorgeous look. And when you look at the FA9 from different angles, you can see a dazzling effect like those of numerous stars in the night sky.

EU IIA Medically Certified - High-transparency skin-friendly resin material
The material of resin is especially important when designing a 3D printed earphone. Thus, we chose to use EU IIA certified, German high-transparency resin for its fine texture, skin-friendliness and comfort, as well as its resistance to discoloration.

Pleasing your eyes and ears - Scientifically-designed ergonomics
Thousands of individuals' ear model data were used in designing the FA9, allowing us to create a smaller design that is comfortable for the vast majority of listeners.

Born light and comfortable
Thanks to the optimized 3D printing manufacturing and skin-friendly resin materials, the FA9 is lightweight at 6.2g per each ear unit and fits closely and comfortably to your ear, further allowing you to enjoy your music.

8 strands of pure audio goodness
The included 8-strand monocrystalline silver-plated copper cable gives you excellent sound quality out of the box, so you don’t have to worry about upgrading to a better cable.
