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.
Voices are so close that you can feel their breathing, giving the nuances and tone of the delicate sound of each musical instrument.
The sound design took into account the relationship between the spatial impression and dynamic range of music and the physical characteristics of earphones and headphones. By exploring the relationship between the spatiality, clarity and dynamic range of music recordings and the physical characteristics of earphones and headphones, we learned that deeper music enjoyment can be achieved through target curves and driver design suitable for the sound design of music recordings.
The B2 is a model that is particularly well suited to room-filling recordings. It is well suited to classical music recordings that make appropriate use of the reflections and reverberation of a concert hall, as well as live recordings to convey the feeling of "being there". In addition, the B2 has an MMCX connector that allows the cable to be changed in the event of a lost connection.

Characteristics
Sound design taking into account the relationship between the spatial impression and the dynamic range of music as well as the physical properties of earphones and headphones.
The sound design for these models took into account the relationship between the spatial impression and dynamic range of music as well as the physical properties of earphones and headphones.
We have categorized the sound generation in music recordings on these two axes: spatial impression and dynamic range.
One way of thinking about this is the perception of distance. In classical and jazz recordings, it is assumed that aspects of spatiality such as sense of distance, width and reverberation are the most important. In rock, pop and many recent animation soundtrack recordings, on the other hand, spatiality is not emphasized as much. It is assumed that there is more emphasis on clarity, which brings the various instruments and vocals to the fore.
Another approach is dynamic range, that is, the change in volume over time. If the dynamic range is large, 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 the individual instruments and voices can appear quite normal before the listener's eye.
The difference between these two ways of thinking is not about which is better, 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 closest to the audience, wind instruments and percussionists 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 eyes of the listener.
Even with classical music, for example,For example, a string quartet would have a narrow dynamic range and the clarity of the individual instruments would be more prominent. In rock and pop music, on the other hand, spatiality is not as important as in classical music and more emphasis is placed on clarity than spatiality.
These requirements are very important, especially for listening with headphones and earphones, and implementing appropriate target curves and driver designs has been shown to result in deeper music enjoyment.
In the graph below, musical spaciousness and clarity are shown on the X-axis and dynamic range on the Y-axis. While our E3000 model targets the middle of the graph, the B-Series is 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 specific type of music that might captivate you so much that you won't want to be without it. This attraction is typical of the products we make.
The B2 is a model that is particularly well suited to room-filling recordings. It is ideal for classical music recordings, where the reflections and reverberation of a concert hall are properly used, as well as for live recordings to give the feeling of being "there". In addition, the B2 has an MMCX connector, which makes it possible to change the cable in the event of a lost connection.
Durable, repairable construction
The two-part design, which can be separated at the front and back, makes the product easy to repair and use for a lifetime.
The feeling of a tailor-made fit
The excellent fit of a headphone 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 because the holding positions for these shapes put pressure on the ear, fatigue sets in over time.
As a result of our renewed return to the basics of our thinking about low-pressure fit, we have arrived at a mindset that includes 2 holding positions and 1 assist position to avoid slipping out.
Similar to a tripod, a stable seat can be secured for each chassis with 3 holding positions.
In the green area of the diagram below (auricle) there is 1 position, in the blue area (tragus) there is 1 position and in the pink area (cavity of the auricle) there is 1 position, for a total of 3 positions.
The tragus secures an earbud to an earpiece in 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 earbud is supported in place by the cavity of the auricle in a way so as not to slip out.
By clearly identifying the contact points, more people's ears can adjust to a fit that does not create a feeling of pressure.
When there is no feeling of pressure, the fit of the headphone is perceived as much more comfortable, and in this way the excellent fit of a seemingly tailor-made headphone is achieved.
Stainless steel housing using the Metal Injection Molding (MIM) process
MIM is a process in which powdered metal is mixed with a binder to form a resin in the desired shape and then subjected to high temperature sintering to achieve the desired shape.
There is a high degree of freedom in molding the resin into the same shape as the casting, making it possible to achieve complex internal design even with metal.

MMCX connector & original OFC cable
The MMCX connector was developed in-house. A soft, flexible, coated material was used, taking into account the contact noise. Even when using ear hooks, it moves flexibly and ensures a good fit.
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.
