DESCRIPTION
A RARE 6 KNOWLES BA DRIVER SETUP FOR A BREATHTAKING SONIC EXPERIENCE
Six Knowles BA drivers per ear, a calibrated 4-way crossover, and a low-frequency ultra-long sound tube are all incorporated in FiiO FA9's design. The FiiO FA9 takes care of the entire audible frequency range with excellence. There is a dedicated SWFK-31376 driver for high and ultra-high frequencies that unite extreme resolution and rich sound. The EJ-33877 custom driver, which FiiO and Knowles collaboratively developed, manages the mid frequencies. The HODVTEC-31618 driver and two woofers perform an excellent job of delivering dynamic and bone-shattering bass with smooth texture. With such a setup at play, you are all set to experience sound like never before.


FIRST-EVER COLLABORATION BETWEEN FIIO AND KNOWLES FOR A CUSTOM BA DRIVER
This is the first time FiiO is utilising EJ balanced armature drivers from Knowles. Both FiiO and Knowles worked collectively to come up with a custom EJ-33877 driver specifically for the FA9. This custom driver delivers mid frequencies with lifelike vocals and instruments.


MASTERFULLY TUNED ACOUSTIC FILTER FOR SMOOTH FREQUENCY RESPONSE AND TEXTURED BASS
To produce the purest sound and seamless integration of multiple drivers, FiiO employed a specially-designed, 80.6mm long sound tube in the FA9. This tube functions as a low-pass filter that keeps unnecessary extra mids and highs away from the driver resulting in a stable frequency response. Moreover, the tube enhances the mids to sound more smooth and clean while also improving the texture of the bass.



3 SOUND ADJUSTMENT SWITCHES THAT LET YOU TAILOR THE MUSIC JUST THE WAY YOU WANT IT
Explore the freedom of tuning the sound as per your preference with the FiiO FA9. The FA9 has an electronic crossover technology consisting of 3 sound adjustment switches. Adjust the impedance, sensitivity, bass, mids and treble for a personalised music listening experience. When switch S1 is turned on, it lowers the impedance and increases sensitivity making the FA9 simple to use with smartphones, tablets, and computers. When switch S1 is turned off, it increases the impedance for a more clean and natural sound, with a darker background and lower audible noise. When switch S2 is turned on, it increases the treble delivering pristine highs. When switch S2 is turned off, you will experience a balanced sound with a lower treble response. When switch S3 is turned on, it reduces the bass and increases mids which adds resolution and good timbre to vocals and instruments like guitars, to name a few. When switch S3 is turned off, it elevates bass and mids are recessed, useful when listening to classical or orchestral music.

FOUR-WAY CROSSOVER DESIGN WITH 80.6MM ULTRA-LONG SOUND TUBE DELIVERING SEAMLESS PERFORMANCE
When there are multiple drivers at work, seamless performance becomes a challenge. To address this, the FiiO FA9 has a four-way crossover design. 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 of 80.6mm in length. This 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. This design perfectly binds the drivers in perfect harmony for coherent low, middle, high, and ultra-high frequencies. The powerful bass, precise yet rich vocals, and detailed yet enjoyable treble on the FA9 will make you appreciate the details and intricacies of your music that you might've been missing all this while.


DESIGNED WITH 4TH GEN DLP 3D PRINTING & DIAMOND-CUT FACEPLATE FOR SHEER ELEGANCE
The use of DLP 3D printing technology gives the shell of the FA9 a distinct look that stands apart from other 3D printed headphones. The highly advanced 4th gen DLP 3D printing technology employed in designing the exterior shell of the FA9. A brand-new diamond-cut faceplate that perfectly complements the translucent-black resin shell is what gives the FA9 a stunning appearance. Instead of using conventional resin, the FA9 uses German, EU IIA approved, high transparency resin that is renowned for its skin-friendly texture, comfort, and stain resistance. The FA9 will astound you with its breathtaking beauty.


FOR ABSOLUTE WEARING COMFORT THAT EVERY MUSIC LISTENER DESERVES
The FiiO FA9 was designed by taking samples of human ears to get the most comfortable and secure fit. The small, comfortable design of the FA9 offers pleasant wearing and listening experience. To add to this experience the FA9 is made with optimised 3D printing technology and comes with skin-friendly resin materials while each unit weighs up to 6.2 grams for lightweight comfort.




HI-RES AUDIO-CERTIFIED IEM WITH 8-STRAND MONOCRYSTALLINE SILVER-PLATED COPPER CABLES AND A WIDE ARRAY OF ACCESSORIES
With the support of 8-strand monocrystalline silver-plated copper cables, the FA9 delivers pure audio integrity, so pure that you won't even think about upgrading it to a better audio cable. These cables come with left blue and red right markings along with MMCX connectors and a gold-plated 3.5mm plug. Listen to your music exactly the way the artist intended with the High Res Audio certified FiiO FA9. 15 sets of ear tips, including three for balanced sound, three for improved bass, and three for enhanced vocals, are included in the FA9's accessory package. There are two sets of foam eartips and Spinfits. Double-flanged tips for deep insertion fit are also included. It comes with a cleaning brush and an SK-01 magnetic cable organiser. The FA9 is packaged in a lovely HB3 leather case that shields it from dust and moisture.
