B2
Sound design taking into account the relationship between spatial impression and dynamic range of music as well as the physical properties of earphones and headphones.
High clarity across the entire frequency range and beautiful sound in the high range make it possible to hear the delicate touch of a piano and the perfect pluck of a guitar.
When designing the sound, the relationship between spatial impression and dynamic range of the music as well as the physical properties of earphones and headphones were taken into account.
By exploring the relationship between spatiality, clarity and dynamic range of music recordings and the physical properties of earphones and headphones, we have learned that deeper music enjoyment can be achieved by targeting curves and driver design that match well with the sound design of music recordings.
The B3 model was designed with clarity in mind. It is intended for those who want to enjoy the delicate sound of each musical instrument in excellent quality even during live recordings and experience the clear vocals from animated soundtracks and EDM. It is equipped with a standard silver sheath cable and has an MMCX connector that allows the cable to be replaced in case of a broken connection.

The sound design for these models took into account the relationship between the spatial impression and the dynamic range of music as well as the physical properties of earphones and headphones.
We have divided the sound generation in music recordings into these two axes: spatial impression and dynamic range.
One school of thought relates to the perception of distance. Classical and jazz recordings are considered to be performed with an emphasis on aspects of spatiality, such as the sense of distance, width and reverberation. Rock and pop music, as well as many of the newer animation soundtracks, do not place as much emphasis on spatiality. The emphasis is considered to be more on clarity, bringing the various instruments and vocals to the fore.
Another approach is dynamic range - in other words, the change in volume over time. If the dynamic range is wide, it is of course possible to use the change in volume over time to achieve a more dynamic expression of the music. However, there are some types of music where recordings with a narrower dynamic range are preferable so that each of the instruments and vocals appear normal to the listener.
The difference between these two ways of thinking is not about which is superior, but rather about how music is composed and what is required of it. In classical music, especially orchestral music, the spatial orientation of the instruments is particularly important. String instruments are positioned close to the audience, wind instruments and percussion instruments behind them.
If the balance between the spatial orientation and the volume of each group of instruments were to break down, the music would disintegrate. For this reason, this type of music does not require a uniform clarity of sound that allows each instrument to appear before the listener's eyes.
Even in classical music, such as a string quartet, the dynamic range would be narrow and the clarity of each individual instrument would be more important. In rock and pop music, on the other hand, spatiality is not as important as in classical music, and so more emphasis is placed on clarity than spatiality.
These requirements are very important, especially for headphone listening, and implementing appropriate target curves and driver designs has been shown to result in deeper music enjoyment.
Please refer to the graph below, which plots musical spaciousness and clarity on the X-axis and dynamic range on the Y-axis. While our E3000 model was designed to be right in the middle of the graph, the B-Series sits outside of this range.
In other words, compared to the E-Series, the B-Series is positioned more as a model for listening to a certain type of music, and you might be so enamored with it that you don't want to do without it. This appeal is typical of the products we make.
The B3 model was designed with clarity in mind and is intended for those who want to enjoy the delicate sound of any musical instrument in excellent quality even during live recordings and enjoy the clear vocals from animated soundtracks and EDM.
It is equipped with a standard silver jacket cable and uses an MMCX connector, which allows the cable to be replaced in case of a broken connection.
Durable, repairable construction
The two-piece, detachable front and back design makes the product easily repairable for a lifetime of use.
The feeling of an individual fit
The superior feel of a headphone's fit is determined by the presence or absence of a feeling of pressure. There are products on the market with an ergonomically lauded, organically curved surface that should be suitable for placement anywhere in the ear, but since the holding positions for these shapes put pressure on the ear, fatigue sets in over time.
Since we've gone back to basics in terms of low-pressure fit, we've come to a mindset that includes two holding positions and a supportive position to keep it from slipping out.
Similar to a tripod, three holding positions can ensure a stable fit for each chassis.
There is one position in the green section of the diagram below (earpiece), one position in the blue section (tragus), and one position in the pink section (concha cavity), for a total of three positions. The tragus secures an earphone with an earpiece in such a way that it is difficult to feel pressure even when force is applied, and the pink section uses a fitting method where the earphone is held in place by the earpiece cavity so that it does not slip out.
By clearly identifying the contact points, more people's ears can adjust to a fit without feeling pressure.
When there is no feeling of pressure, the fit of the headphone is perceived as all the more comfortable, and in this way the superior fit of a seemingly tailor-made headphone is achieved.
metal injection molding (MIM) stainless steel housing
MIM is a process in which metal powder is mixed with a binder to form a resin in the desired shape and high temperature sintering is used to achieve the desired shape.
Balanced Armature Driver x2
Uses two Balanced Armature (BA) drivers, one for the high frequency range and one for the mid and bass. The sound sent to each driver is not divided into specific frequency bands by a network.
MMCX connector and original OFC silver-plated cable with high purity
The MMCX connector was developed in-house. We used high purity OFC silver-plated cables that provide a wide sound stage. These jointly developed cables were originally designed and are currently manufactured by the renowned company Junkosha for use with the "Kei" supercomputer due to their high signal transfer speed.
The insulating film is made of PFA, also developed by Junkosha, who used their extensive know-how through the JUNFLON® brand to create the ultimate low dielectric constant material.
The outer tube is made of PVC for maximum flexibility. The user will experience surprising flexibility, making the cable both extremely user-friendly and reducing the likelihood of microphonics.
In addition, the MMCX connector and 3.5mm mini-plug are prone to loosening, so we have far exceeded the regular quality assurance criteria of 5,000 times bending test by modifying the connector design to withstand more than 50,000 bends.
* Junkosha: The Japanese company Junkosha develops and manufactures products such as high-speed coaxial cables, which offer the fastest transmission speed in the world at 95% of the speed of light, as well as cables for demanding areas such as shipping and aerospace, healthcare and power generation plants. These special cables require a high level of technology and are based on fluoropolymers. Junkosha's cables are often sold under the brand name JUNFLON® and enjoy the enormous trust of engineers who
require special cables.
Original ear tips with a color difference between the left and right socket.
Two types of silicone are used for the sound conductor and the earplug that comes into contact with the user's ear, which differ in their firmness. The silicone used for the sound conductor is stiffer than that used for the earplug, and combines both firmness and flexibility through the groove processing. Soft silicone is used for the earplug, which ensures a comfortable fit and high sound insulation.
One of the jacks is gray, the other red; if you pull the earpiece back slightly to check the jack color, you can easily distinguish between left and right, even in places with dim lighting. Since the jack colors of adjacent sizes are different (the gray jacks alternate between dark and light gray; the red jacks alternate between red and pink), it is also easy to distinguish between the sizes.
Available in 5 sizes - SS/S/M/L/LL
Ear hooks that reduce the noise of the cable
Similar products were designed to be adjustable to fit ears of different sizes; not only were they large, they were also visually too prominent and it took a lot of getting used to adjusting them.
After considering what the key to ear hook customization is, we discovered a shape that is smaller than existing ear hooks, that does not use metal or resin wires, and that fits more people's ears.
We've achieved something that's slim and doesn't feel foreign, providing a level of comfort that makes you forget you're wearing it. It's also easy to pair with a figure-of-eight cable.
Cable noise - the unpleasant sound created when the cable touches the user's body while walking - is drastically reduced.
silicone carrying case
This silicone case allows the cables to be rolled up and easily stored. The earbuds themselves are gently secured by thin, dome-shaped silicone sleeves.
aging
Aging is a phenomenon in which sound changes with continued use over a period of time. A driver unit produces sound through the vibration of an extremely thin, heat-formed film.
The cause of this is unclear, but it is thought that the film becomes accustomed to the stress from the molding of the film or the stress from the adhesive when used for a long period of time, allowing tiny signals to be easily transmitted.
A long period of time is required for the aging effects to become imperceptible on this product. In general, after 150 to 200 hours of normal use, the sensitivity will increase to reach the level of sound quality for which the product was originally designed.
