FAudio / FA2507

Faudio Spring is a new generation flagship dynamic in-ear monitor that embodies the brand's philosophy and concept.

■New generation dynamic driver
The second generation driver uses a dual diaphragm structure. A titanium diaphragm is used for the mid-high range, and a composite fiber diaphragm is used for the mid-low and heavy bass ranges. Combining the best of both worlds, our unique patented technology ""Triple Built-in Acoustic Chamber (T.B.A.C)""
This reduces the effect of air flow on sound wave conduction, resulting in more efficient overall performance.
In addition, the new generation driver uses a new magnetic method to improve the driving force of the coil's magnetic force and achieve high energy efficiency. Compared to the previous generation structure, the expressive power of sound and frequency extension have been improved. Pure silver wire is used for internal wiring to ensure signal transmission quality, further increasing sound fidelity.

■Triple Built-in Acoustic Chamber
It uses a technology called T.B.A.C (Triple Built-in Acoustic Chamber). Traditional frequency instability and extraneous effects that occur when sound travels
This eliminates heavy airflow and opens up a wide range of possibilities for tuning methods.

■Specially designed cable
The genuine cable used for Spring is a 4wire cable with a mixed core of pure copper wire and pure silver wire. The outer layer of the core wire is made of ultra-soft fiber, a denser material in the same color as the IEM, with an added layer of protection to prevent oxidation of the conductors. This increases the durability of the wire while maintaining its flexibility and storage.
