The balanced armature flagship model that eliminates compromise in the pursuit of ideal sound.

Achieves a delicate, soft sound field that carries.

BAM (Balancing Air Movement) Mechanism
To enhance the bass performance and musicality of balance armature drivers to another level, Final has developed the Balancing Air Movement (BAM) mechanism. With the optimization of airflow with the specially designed housing, the FI-BA-SST can reproduce seductive bass tones, preventing the listener from getting tired easily or listing to a very flat sound.
Original balanced armature driver unit
Since the BAM mechanism optimizes the flow of air within the housing, according to our own unique specifications, an opening has been established on the back of the driver unit, which is usually closed.
Highly rigid machined stainless steel housing
There are five pieces per side to the housing, which has been machined from stainless steel. In the pursuit of the ideal BAM mechanism, special care has been taken even with the parts of the housing you can’t see, every part of which has been created using extremely complex manufacturing processes. Usually the cable is connected within the housing to secure it. With this FI-BA-SS, however, we’ve employed a collet chuck to secure the cable, so that the air flow through the inside of the housing is not compromised. The high-precision processes used even in such hidden aspects of the product support FI-BA-SS’s outstanding sound quality.
Original high purity OFC silver coated cable
We’ve used high-purity OFC silver coated cables that provide a wide sound stage. These jointly-developed cables were originally designed by and are currently manufactured by the well-renowned Junkosha corporation for the purpose of being used with the supercomputer “Kei” due to their fast signal transmission speed. The insulator film is made from PFA which was also developed by Junkosha who used their extensive know-how through the JUNFLON® brand to create the ultimate in low-permittivity material. The outer tube is made from PVC for maximum flexibility. The user will experience surprising flexibility that both makes the cable extremely easy to use as well as reducing the likelihood of microphonics. In addition, the mini-plug have a tendency to disconnect so we’ve far exceeded the regular QA pass criteria of a 5,000-time bend test by changing the connection design to one that can withstand more than 50,000 bends.
