Final Audio Fi-BA-SST35 Balanced Earphones (3.5mm Plug)
The balanced armature flagship model that eliminates compromise in the pursuit of ideal sound.
Achieves a delicate, soft sound field that carries.
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. Two models have been prepared, Fi-BA-SST35 Balanced Earphones (3.5mm Plug) and Final Audio Fi-BA-SST25 Balanced Earphones (2.5mm Plug).
As noted below, with the balanced armature driver unit, iron fragments are activated for sound emission, a configuration with a variety of problems; at final, we solved these problems using the methods below.
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.
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.
The new style E type CLEAR earpieces employ two types of silicon differing in rigidity for the sound conduit and for the section that comes into contact with the user’s ear. For the sound conduit, a more rigid silicon has been used compared to that used with the section coming into contact with the user’s ear with a view to achieving both strength and flexibility. The earpiece is fitted into the ear while maintaining its round shape. Soft silicon has been employed for the section that comes into contact with the user’s ear, making for a comfortable fit and a high level of sound insulation. Compared to the black, the surface smoothness and solidity differ slightly; with slight changes to the airtight nature of the product, bass tones are slightly softer, while high-pitched tones can be heard clearly, making for a tendency to clear sound. The product comes in a set of five sizes, SS/S/M/L/LL. C type BLACK (S/M/L) with its differing airtight nature and bass tone reproduction is included along with the E type clear. Please choose the type that you prefer.
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.
?Junkosha: The Japanese corporation Junkosha develops and manufactures products such as high speed coaxial cables that boast the world’s fastest transmission speed at 95% the speed of light, as well as cables for demanding fields such as marine and aerospace, healthcare and power generation facilities. These special cables require a high level of technology and center around fluoropolymers. Junkosha’s cables are often called by the brand name JUNFLON® and have earned the tremendous trust of engineers requiring special-purpose cables.
?A total length of 1,200 km is now being used in supercomputers, and it takes longer for the electrons to flow through the cables than it does through the semiconductor.
As the cable transmission speed is the limiting factor of the supercomputer speed, a substantial amount of development costs are spent in the pursuit of transmission speed.
A BAM vent has been established on the back of the housing to allow for both the control of airflow and to prevent sound leakage.
