Final Audio FI-BA-SST25 Balanced Armature Driver Earphones

Final Audio


$ 1,299.95



Achieves rich, three-dimensional spatially expressed sound reproduction deemed difficult with a balanced armature driver.Employs a single driver networkless direct connection circuit.Using an extremely complex assembly process possible because it is carried out at our own factory here in Japan, this flagship model unlocks the utmost potential of the single balanced armature driver.Silver coated cables are employed, making for beautifully lingering soft high frequencies while retaining the delicacy of BA-SS. A polished sound with natural power of expression.
BAM mechanism produces bass sounds and stereo spatial interpretations
With balanced armature driver units, iron is driven to produce sound, and as such, these drivers face a number of problems, amongst which are "proving tiring to listen to", "having sound that is subtle and beautiful, but lacking in depth and being flat” and "lacking bass interval". At final, we decided to focus on developing technology for the reproduction of bass tones and three-dimensional space with the full-range reproduction of a theoretically unproblematic single driver unit, rather than taking things in a multiway direction. We went back to the beginning and reviewed the performance of the balanced armature driver, focusing our attention on something we had previously overlooked ? airflow inside the housing. We developed BAM (Balancing Air Movement), a mechanism that optimizes airflow inside the housing through the creation of an aperture in the driver unit, which is usually sealed. 

While achieving bass tones and deep, three-dimensional spatial representation, which proved difficult with single driver full-range reproduction, we achieved a BA type that at the same time made for natural listening the user doesn't tire of.
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.
