Final B3 Dual Drivers IEM Earphones

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.

The B3 model was designed with particular emphasis on clarity. It caters to those who wish to have the delicate sound of each musical instrument delivered gorgeously even from live recordings and enjoy tight vocals from animated soundtracks and EDM. It comes equipped with a standard silver coat cable and employs an MMCX connector that makes it possible to switch cables in the event of a severed connection.

Sound design with consideration to the relationship between the spatial impression and dynamic range of music as well as the physical characteristics of earphones and headphones

Sound design for these models has been undertaken with attention to the relationship between spatial impression and dynamic range of music, and the physical characteristics of earphones and headphones. We have categorized sound creation on music recording onto these two axes: spatial impression and dynamic range.

One way of thinking regards distance perception. Classical and jazz recordings are thought to be performed with an emphasis on aspects of spaciousness, such as a sense of distance, broadness and reverberation. On the other hand, with rock, pop and many of the recent animation soundtrack recordings, spaciousness is not as highly emphasized. There is thought to be a 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. In classical music, and that played by the 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 a 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 results in deeper enjoyment of music.

Please refer to the below graph with the 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 the aim at the very centre 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

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 to be 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 and reduces the likelihood of microphonics. In addition, the MMCX plug and the 3.5 mm mini-plug tend 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.

* Junkosha: The Japanese corporation Junkosha develops and manufactures products such as high-speed coaxial cables that boast the world’s fastest transmission speed at 95% the speed of light, as well as cables for demanding fields such as marine and aerospace, healthcare and power generation facilities. These special cables require a high level of technology and centre around fluoropolymers. Junkosha’s cables are often called by the brand name JUNFLON® and have earned the tremendous trust of engineers requiring special-purpose cables.
