Final Audio B2 IEM Earphones

Final Audio B2 IEM Earphones

 

The Final Audio B2 IEM Earphones offer a compelling reason to invest in high-quality audio equipment, providing an immersive listening experience that considers the nuanced relationship between spatial impression, dynamic range, and the physical attributes of earphones and headphones. With meticulous attention to sound design, the B2 model delivers vocals with such proximity that one can feel the respiration, capturing the delicate nuances and inflections of each musical instrument with remarkable clarity.

Designed to cater to rich spatial recordings, the B2 excels in reproducing classical music and live performances, leveraging reflections and reverberations to create a sense of presence. Its sound design philosophy, grounded in the understanding of spaciousness, clarity, and dynamic range, ensures a deeply engaging musical experience that transcends conventional boundaries.

Featuring an MMCX connector for cable interchangeability and a durable Metal Injection Molding (MIM) stainless steel housing, the B2 combines robust construction with refined aesthetics. The inclusion of original earpieces with colour-coded bushes and five different sizes ensures a customised fit tailored to individual preferences.

Furthermore, the B2 incorporates innovative ear hooks designed to alleviate cable touch noise and enhance comfort without compromising on performance. The slim and ergonomic design of the ear hooks minimises interference, allowing users to enjoy uninterrupted listening sessions.

With additional features such as a silicon carry case for convenient storage and aging considerations that ensure long-term performance, the Final Audio B2 IEM Earphones offer a comprehensive solution for audiophiles seeking superior sound quality and comfort. Whether you're an enthusiast of classical orchestras or contemporary rock music, the B2 promises to elevate your listening experience to new heights, making it a worthy investment for discerning music lovers.

Long-Life, repairable construction

The front-rear two-piece separable construction makes the product easy to repair for a lifetime of use.

 

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.

MMCX Connector＆Original OFC cable

The MMCX connector was developed in-company. Taking touch noise into consideration, soft, flexible coated material has been employed. When using ear hooks also, it moves flexibly, making for a good fit.

 

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; the red bushes alternate between red and pink), it is also easy to distinguish between sizes.

 

Comes in 5 sizes – SS/S/M/L/LL

 

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.
