Final Audio B1 IEM Earphones

Final Audio B1 IEM Earphones

 

The Final Audio B1 IEM Earphones are an exceptional choice for those seeking a premium audio experience. These earphones are meticulously designed with a focus on sound design excellence, taking into account the relationship between spatial impression, dynamic range of music, and the physical characteristics of earphones and headphones. As a result, users can expect high clarity vocals and instruments, coupled with an overwhelming sense of liveliness akin to being at a live performance.

One of the key highlights of the B1 earphones is their tailored sound experience. The sound design process considers various music genres and recording styles, ensuring that playback remains faithful to the engineer's intended balance of sound. Whether you're listening to classical orchestral pieces or modern animation soundtracks, the B1 earphones deliver an immersive and authentic soundstage that captivates the listener.

Durability and longevity are also prioritised features of the B1 earphones. With a front-rear separable construction, these earphones are designed for easy repair, ensuring a lifetime of use. This durable design not only enhances the longevity of the product but also offers peace of mind to users, knowing that their investment is built to last.

Comfort is another area where the B1 earphones excel. Designed with comfort in mind, these earphones offer a superior fit with minimal pressure on the ears. The innovative fit mechanism utilises multiple holding positions to ensure stability and comfort, even during extended listening sessions.

Crafted with Metal Injection Molding (MIM) stainless steel housing, the B1 earphones boast exceptional durability and a sleek aesthetic. The combination of balanced armature and dynamic drivers delivers a rich and detailed audio experience across the entire frequency range, making them suitable for a wide range of music genres and preferences.

The B1 earphones come equipped with high-purity OFC silver-coated cables, developed in collaboration with Junkosha, a renowned manufacturer known for its expertise in cable technology. These cables offer fast signal transmission and exceptional durability, ensuring a reliable connection even after extensive use.

Additionally, the B1 earphones come with a silicon carry case, allowing for easy and safe storage of the earphones and cables. The compact and portable design makes it convenient to carry your earphones wherever you go, ensuring that you can enjoy your favourite music anytime, anywhere.

The Feeling of a Customised Fit

Superior feeling of fit of an earphone is determined by the presence or lack of a feeling of pressure. There are products on the market with an ergonomically praised organically curved surface that should be suitable for placement somewhere in the ear, but because the holding positions for those shapes place pressure on the ear, fatigue accumulates over time.

As a result of having newly returned to the basics with regard to our thinking about fit with little sense of pressure, we have arrived at a way of thinking that involves 2 holding positions and 1 assisting position so as to not slip out.

Much the same as a tripod, a stable fit can be secured for any chassis with 3 holding positions.

In the green section of the diagram below (earpiece) is 1 position, the blue section (Tragus) is 1 position, and the pink coloured section (cavity of the concha) is 1 position for a total of 3 positions. The tragus secures an earphone with an earpiece in such a way that makes it difficult to feel stress even when force is applied, and the pink section adopts a fit method in which the earphone is supported in place by the cavity of concha in such a manner as to not slip out. By clearly identifying the points of contact, more people’s ears can conform to a fit with no sense of pressure.

If there is no sense of pressure, the fit of the earphone will be felt to be that much more comfortable, and in this way, it achieves the superior fit of a seemingly customised earphone.

Metal Injection Molding (MIM) stainless steel housing

MIM is a process by which powdered metal is mixed with a binder to form a resin in the desired shape and applying high-temperature sintering to achieve the desired form.

There is a high degree of freedom in molding the resin into the same shape as the cast, making it possible to achieve a complex internal design even with metal.

 

BA+Dynamic Driver Unit

Employs a total of 2 drivers: 1 Balanced Armature (BA) driver for high range sound and 1 Dynamic Driver for bass. There is no parsing of the frequency range by a network.

 

MMCX Connector＆Original high purity OFC silver coated cable

The MMCX connector was developed in-company. 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 MMCX plug and the 3.5 mm 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 centre 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.

 

Original earpieces with a colour difference between the left and right bushes.

Two types of silicon differing in rigidity are employed for the sound conduit and for the earbud that comes into contact with the user’s ear. The silicon used for the sound conduit is more rigid than that used for the earbud, and by having groove processing applied to it, combines both strength and flexibility. Soft silicon has been employed for the earbud, making for a comfortable fit and a high level of sound insulation.

One of the bushes is grey, while the other is red; by pulling the earpiece back slightly to check the colour of the bush, it is easy to distinguish between left and right, even in places with subdued lighting. Since the bush colours of neighbouring sizes are different (the grey bushes alternate between dark and light grey

 

Ear hooks that alleviate cable touch noise

With similar existing products, it was assumed that they would be fitted to ears of differing sizes; not only were they large in size, their appearance was rather too distinct, and it took a lot to get accustomed to fitting them. Having considered what the key to fitting the ear hooks was, we discovered a form that was smaller than existing ear hooks, that didn’t utilise metal or resin wires and fit the ears of more people. We’ve achieved something that is slim and does not have a foreign feel to it, making for the kind of comfort that has you forgetting you’re wearing them. There’s also no problem with combining it with a figure 8 cable.

Cable noise – the unpleasant noise that occurs when the cable touches the user’s body when they are walking – is dramatically reduced.

 

Silicon carry case

With this silicon carry case, the cables can be rolled up and stored easily. The earphones themselves are gently secured using thin dome-shaped silicon covers.

 

Aging

Aging is a phenomenon by which sound changes by continued use over a certain period of time. A driver unit produces sound through the vibration of an extremely thin heat-formed film. The cause is not clear, but it is thought that the film might become accustomed to the stress applied from the forming of the film or stress from the adhesive through continued use over time so that minute signals can be transmitted easily. A long period of time is required before the aging effects on this product become unnoticeable. Generally, through 150 to 200 hours of ordinary use sensitivity increases to achieve the level of sound quality for which the product had been originally designed.
