TheFiiO FA7sare the new in-ear headphones with 6 Balanced-Armature drivers and third-generation industrial design, as well as a high-purity monocrystalline cable. 

Its stainless steel construction and the option to exchange its connectors make the FA7s an ideal alternative for dedicated use. 

The FA7s is equipped with 6 BA drivers. Each set of drivers handles a specific frequency range that has its own sound chambers to greatly minimize frequency interference.

Both the low-frequency driver set and the high-frequency set are made by Knowles, resulting in very extended robust but controlled bass, as well as delicate and highly detailed highs.

The midrange driver is a custom unit made exclusively for FiiO, with lush vocals and an exceptionally pure natural sound.

The FA7S's expertly tuned three-way crossover allows each driver in a 1:1:1 averaging manner to balance the high, mid and low frequencies, and separates them using the "2 + 2 + 2" method.

Each frequency range takes two different drivers that are engineered into an electronic and structural crossover system for precise cutting, resulting in a more realistic and balanced sound, fully capable of reproducing every last detail and emotion in your music, just as the artists intended.

The FiiO FA7s is made from medical grade 316L stainless steel and is meticulously handled through a high temperature powder metallurgy process after injection molding to eventually form the entire earphone construction. 

Its front plate is processed through a five-axis CNC machine, and the rear cavity is hand-polished to a shiny, dazzling, mirror-like finish. Additionally, 316L stainless steel goes through a PVD electroplating coating process for significantly higher rigidity.

The FiiO FA7s adopt FiiO's third-generation industrial design with its distinctive elements, such as Y-shaped elements reminiscent of windmills, 120º angles, tri-circular faceplate, all working in harmony to create a balanced sound through a smart and expensive design.

Each FA7 earpiece unit is made of stretched stainless steel and bright blue steel mesh, along with its other unique visual elements, come together in an intricate design that is aggressively bold and pleasantly relaxing.

The FA7s with a high-purity silver-plated monocrystalline wire cable: 8 strands of 19 wires each for a total of 152 wires.

Each wire is individually insulated and all are Litz-style braided. The outer sheath of the cable is made of environmentally friendly TPU, and is resistant to yellowing after long-term use and hardening in low temperature environments.

Every detail of the FA7s cable has been optimized for your comfort and ease of use.

Expanded angle MMCX connectors with left "blue" and right "red" indicators make it easy to connect and disconnect the FA7, while the curve of the ear hook is based on scientific research to fit comfortably in your ears.
