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.
Construction and Fit
The front-rear two-piece separable construction makes the product easy to repair for a lifetime of use.
Metal injection molding 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.
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.
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.
Original earpieces with a color 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 gray, while the other is red; by pulling the earpiece back slightly to check the color of the bush, it is easy to distinguish between left and right, even in places with subdued lighting. Since the bush colors of neighboring sizes are different (the gray bushes alternate between dark and light gray; the red bushes alternate between red and pink), it is also easy to distinguish between sizes.
