Final Audio - B Series B1 Earphone (BA and Dynamic Driver)

Sound design with consideration to the relationship
between spatial impression and dynamic range of music,
and physical characteristics of earphones and headphones.
Clarity of vocals and each musical instrument is extremely high,
overwhelming presence and feeling of
liveliness as if standing in the center of a live stage.

Sound design has been undertaken with consideration to the relationship between the spatial impression and dynamic range of music, and the physical characteristics of earphones and headphones. Through research into the relationship between spaciousness, clarity and dynamic range of musical recordings, and the physical characteristics of earphones and headphones, we have learned that deeper enjoyment of music can be achieved through the target curves and driver design well suited to the sound design of music recordings. B1 is a model designed with particular emphasis on proximity of sound and sense of reality. In music represented by animation soundtracks, recordings make the proximity of sound more conspicuous. For this type of music recording, the B1 has been designed to achieve playback more consistent with the balance of
sound as created by the engineer.

One way of thinking regards the distance perception. Classical and jazz recordings are thought to be performed with emphasis on aspects of spaciousness, such as sense of distance, broadness and reverberation. On the other hand, rock, pops and many of the recent animation soundtrack recordings, spaciousness is not as highly emphasized. There is thought to be greater emphasis on clarity, which brings the various instruments and vocals to the front.

Another approach is dynamic range - in other words, changes in loudness over time. If the dynamic range is wide, naturally it is possible to use the change in loudness over time to achieve a more dynamic expression of music. But, there are some types of music for which narrower dynamic range recordings are preferable to allow each of the instruments and vocals to ordinarily appear before the listener’s eyes.

The difference between these two ways of thinking pertains not to which is superior but rather differences in how music is composed and what is demanded of it. With regard to classical music, and that played by orchestra in particular, the spatial orientation of instruments is particularly important. Stringed instruments are positioned nearest to the audience with wind and percussion placed behind them. Should the balance between the spatial orientation and volume of each group of instruments collapse, the music would disintegrate. For that reason, uniform clarity of sound that allows each instrument to appear before the eyes of the listener is not demanded of this type of music. Even for classical music, a string quartet, for example, would have a narrow dynamic range and the clarity of each instrument would be more prominent. For rock and pops on the other hand, spaciousness is not as necessary as for classical music, and so there is greater emphasis on clarity than spaciousness.
These preconditions are very important, particularly for earphone and headphone listening, and it has become apparent that the implementation of appropriate target curves and driver design result in deeper enjoyment
of music.

Please refer to the below graph with spaciousness and clarity of music set on the X axis and dynamic range set on the Y axis. Whereas our E3000 model was designed with aim at the very center of the graph, the B series is positioned outside that area.
In other words, in comparison to the E series, the B series is positioned more as a model to listen to a specific type of music, and you might become so enthralled with it that you can’t do without it. This attraction is typical of the products we produce.

The Feeling of a Customized 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 colored 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 customized 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.

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.

Sound quality: Clarity of vocals and each musical instrument is extremely high, overwhelming presence and feeling of liveliness as if standing in the center of a live stage.
