amazon FiiO FA9 reviews

FiiO introduces a new flagship in-ear model called FiiO FA9. That is the flagship model of the Full Balanced Armature headset line with 6 BA drivers; the housing is 3D-DLP printed. With the ability to adjust impedance and sound quality with a switch directly on the headset.

1. Designing 6 BA Drivers

The 6 BA drivers (3 driver pairs) of the FiiO FA9 headphones are all manufactured by Knowles. Pair of SWFK-31736 for high range and soundstage; The EJ-33877 is for the midrange, and the HODVTEC-31618 woofers are for the low end.

The pair of midrange drivers EJ-33877 is Knowles’ new generation special driver designed specifically for FiiO. Knowles’ EJ line is often known for its Flagship Hi-end headphones because of the extremely high price tag for a pair of BA drivers.

The three pairs of drivers above all use a separate sound pipe. Specially designed with a length up to 80mm intended to act as a low-pass filter circuit. Help reduce resonance in the mid-range and high-range of the drivers and give a balanced and accurate bass range.

2. Tone-control and impedance switch

An extremely interesting point of the FiiO FA9 headset is the use of switches not only to adjust the tone control but also to adjust the impedance and sensitivity of the headset. You can see three different switches S1, S2, S3. Each switch will have a different effect.

S1: Impedance adjustment switch.

ON: reduce impedance, increase sensitivity so that common mobile devices can be easily used (16 Ohm/113dB)

OFF: Off increases impedance, cleaner sound, reduces noise and darker background (32 Ohm/110dB)

S2: High range tuning switch

ON: increased energy and high-band detail for those who like bright sounds or listen to rock

OFF: reduce high-band energy for a more balanced sound suitable for most genres

S3: Bass range adjustment switch

ON: reduce the bass range; the midrange is raised, suitable for those who like to listen to vocals and instruments.

OFF: Increases the depth of the bass range, the midrange is slightly back, suitable for classical and symphony genres

3. 3D printing technology

The housing part of the FiiO FA9 is completely 3D printed using the new generation DLP 3D printing technology to ensure the precision to every detail and the complex sound chamber that most previous methods can hardly do. The parts of the headset are fixed and glued with UV glue.

Housing printing material is EU-IIA Class European medical standard resin with high transparency, firmness and still ensures no irritation and comfort for users for a long time.
