FiiO's New 6 Balanced Armature IEMs FA7S Is Officially Released! Firing on all frequencies, 6 Knowles BA drivers

Firing on all frequencies, 6 Knowles BA drivers

The FA7S is equipped with 6 balanced armature drivers, with each set of drivers handling a specific frequency range having their own sound chambers so as to greatly minimize frequency interference. Both the low frequency set and high frequency set of drivers are made by Knowles – resulting in greatly extended, robust, yet controlled bass as well as highly detailed, delicate treble. The mid-frequency driver is a custom unit exclusively made for FiiO, with lush vocals and an exceptionally pure, natural sound.

Multi-driver IEMs require a precise crossover system other than the drivers themselves applied. Therefore, we expertly designed the FA7 with a three-way crossover, which enables each driver in an average 1:1:1 way and separates them using the "2+2+2" method. Besides, each frequency range takes two different drivers which are designed in an electronic and structural crossover system for precise cutting – thus resulting in a more realistic, balanced sound fully capable of rendering every last detail.

From A to Z, we have been exploring more advanced workmanship to make for a premium using experience for our users. The FA7S is made of medical-grade 316L stainless steel meticulously handled through a powder metallurgy process- 1000 degrees Celsius of high temperature sintering after injection molding to eventually form the whole earphone construction. Its faceplate is processed through a five-axis CNC machine, and every unit is polished by hand for a shiny, dazzling, mirror-like finish. In addition, the 316L stainless steel goes through a PVD electroplating coating process for significantly increased rigidity.

There are more lovable features, such as the high quality silver-plated monocrystalline copper cable, angled MMCX connectors, twist-lock swappable audio plugs and Hi-Res Audio certification.
