Top-quality earphones.

Inside each FA7, there are 4 Knowles BA drivers. Bass is handled by the CI-22955, which provides robust, low-distortion bass due a much bigger diaphragm than a typical BA driver. Mids are provided by the classic and proven ED-29689, with its full, sweet sound. Treble is produced by the dual-BA SWFK-31736 driver, specifically customized for the FA7 to bring extremely extended and detailed highs, for a natural and clear sound.

Unlike traditional manufacturing processes with its inherent constraints, 3D printing allows Fiio to fully realize the goal of creating an IEM that is both pleasant to wear and maximizes sound quality through an acoustic-optimized shell design.

The FA7 is the first mass-produced, 3D printed quad balanced armature in-ear monitor. This is made possible through a collaboration between FiiO and 3D printing specialists HeyGears, using advanced industrial-grade 3D printers using DLP printing technology with printing resolution up to 25um. Each pair of FA7 shells are precisely crafted through 60 minutes of printing, with thousands of DLP projections and careful movements. The result is remarkably consistent sound between pairs of FA7’s, as well as reduced sonic resonances that allow the music to flow through unimpeded.

A skin-friendly shell with remarkable resilience
The shell of the FA7 is made with German high-transparency resin, specifically medically designed for ears and with EU IIA medical certification. The skin-friendly resin is both comfortable and antimicrobial while also being extremely durable and resistant to discoloration, ensuring the FA7 continues to exhibit its striking transparent appearance for

BA driver IEMs vs hybrid IEMs
BA driver IEMs like the FA7 and hybrid IEMs like the FH5 offer different types of sound, not that one type is better than the other. The FH5 is the warm, inviting gentleman that moves about with grace, while the FA7 is the wilder younger brother. With its highly resolving nature and excellent transient response unique to BA drivers, the FA7 provides an alternative exciting experience that complements the one found in the FH5.

Hi-Res Audio certified
The standard FA7 cable is made of high-purity monocrystalline copper-plated silver wire, ensuring that your music is transferred with minimal distortion and without loss for the most transparent sound possible. The cable is also detachable and replaceable with an MMCX design, so that the FA7 is not merely just a paperweight if its cable goes bad.

Providing you with a tailored, customized experience
With the FA series of in-ear monitors, you will be provided with a variety of shell designs to choose from, to get a unit custom-made for you.

Beautiful and elegant style

The best designs are the results of constant experimentation. After having gone through countless ideas and revision, the FiiO design team came up with the final 3 complex, yet visually-arresting designs. Each design is wonderfully stimulating with its layers upon layers, and is largely possible due to the precision of 3D printers. Included with the FA7 are 13 different pairs of ear tips: 3 different sets of small, medium, and large pairs of ear tips, designed for either a balanced, bass-emphasized or vocal-emphasized sound signature. Also included are 3 pairs of foam ear tips all in medium and 1 pair of bi-flange ear tips. With the FA7, get the sound signature you want by simply switching to the ear tips right for you.
