SINGAPORE – Here in Singapore, we get our first look at the FA9 from FiiO Electronics Technology Co. Ltd. (FiiO), the company’s brand new in-ear monitor. The FA9’s state-of-the-art design and six Knowles BA drivers in each ear canal ensure crystal-clear sound. Its transparent, diamond-cut casing sparkles from every aspect.

Your audio fantasy 

The latest FA9 from FiiO features six Knowles BA drivers in each earcup and a carefully crafted four-way crossover that together span the whole audible frequency range. It’s worth every penny because of the dramatic bass, crystal clear, and very detailed sound quality that this carefully crafted design was meant to produce. The SWFK-31376 driver it uses for high and ultra-high frequencies combines extraordinary resolution with a full sound, while the EJ-33877 bespoke driver, co-designed by FiiO and Knowles, guarantees excellent mids that deliver lush vocals.

Knowles EJ balanced armature drivers, traditionally used solely in high-end in-ear monitors, are included in FA9 for the first time thanks to FiiO. (IEMs). Its HODVTEC – 31618 driver has 2 woofers built into it, so even at low volumes, you’ll get a powerful and dynamic bass. The carefully crafted technology available today can produce and immerse you in a world of unreal yet believable sounds, allowing you to live out your wildest sonic fantasies.

Additionally, the new FiiO FA9 features an ultra-long sound tube measuring in at 80.6mm in length, which eliminates additional mids and highs from the drivers to provide a continuous and unbroken frequency response. This sound tube ensures that the various drivers do not conflict with one another, resulting in clear, distortion-free music. It reinforces the bass’s texture while also guaranteeing a clean and even mid-bass.

Be your own DJ 

Thanks to the crossover technology in FA9, you may play DJ for yourself by selecting from one of eight distinct sonic profiles. Pick the ideal listening experience for your preferences. The first toggle changes the impedance, the second boosts the treble, and the third controls the bass. You can create your own unique listening experience by toggling the sound controls to suit your preferences, be they for a more pure, natural sound or for booming highs and lows à la rock.

A design complementary to its exquisite sound quality 

Cutting-edge, state-of-the-art, and entirely 3D printed: the FA9’s outer casing is made using DLP 4th generation 3D printing. The new earbuds have a precise and sturdy structure designed to maximize audio quality, thanks to advancements in printing accuracy, efficiency, and curing uniformity.

It has a brand-new faceplate with a diamond cut that, like the sound quality, is nothing short of spectacular. Not only does it sound great, but the iridescent look seen from every angle blends well with the translucent-black resin shell. Thanks to its ergonomic design, the FA9 IEM provides users with a pleasant, distraction-free listening experience. It makes use of a German high-transparency skin-friendly resin material that is certified by the EU IIA for medical use and is resistant to discoloration, making for a comfortable fit and user experience even after extended wear.

Other features include: 

  • Light in weight but heavy in tone – Weighing only 6.2g per ear unit, the skin-friendly resin material that is employed by FA9, promises an enjoyable and comfortable listening experience.
  • Protect its exterior, safeguard its interior – Made of faux leather, the self-closing case ensures full protection of the in-ear monitor, with a mesh storage area as well as an inner lining protection.
  • 8 strands of pure audio goodness – The 8-strand monocrystalline silver-plated copper cables included in the box supports excellent sound quality so you don’t have to worry about upgrading to a better cable.
