Enjoy this in-depth interview with the Nittoku's two titans of the earphone/headphone industry, Chairman Komoda and Technical Manager Takashima, who brought the newspring NSE1000 series into creation!
We've known each other for about 47 years now. Throughout this time, we’ve been working together on OEM business for major audio manufacturers for many years.
Of course, we’ve always been researching sound that is
faithful to the source. Still, in developing Nittoku's proprietary inner ear headphones for the first time, rather than aiming to be the number one, we wanted to create a unique pair of inner ear headphones full of originality.
Also, since we are of the vinyl generation, vinyl records were the warm sound that got us interested in acoustics. In this day and age, digital technology has its own merits. However, there are still fans of the sound of vinyl records all over the world, and we wanted to create a product that could convey the warmth of that unique analogue sound.
Even in today's digital age, earphones, headphones and speakers are still very much analogue. And that especially applies to the internal parts of in-ear headphones, such as the diaphragm and voice coil. These have remained basically unchanged over the decades. However, in-depth development is required as we begin to pursue good sound.
In specific times, rigidity and lightness are required for high frequencies. At the same time, suppleness and weight are necessary for lower frequencies. In other words, we need to achieve a balance between these two opposing elements.
I think this is what the engineers at each company have been struggling with for many years.
The newspring NSE1000 uses a new material that has rarely been adopted until now.
One of these is a rigid material for the diaphragm called super engineering plastic, which was recently developed.
The second is a material that combines suppleness and rigidity by applying carbon coating to a polymer film that has been conventionally used.
For the voice coil, three special types of wire are used, for which the ratio of aluminum wire to the copper that covers it was finely tuned after repeated prototyping.
In the prototyping phase, we had several of these candidate materials for each part. There are also several different materials for the housing of the inner ear headphones, plus several types of cables. Combining each of these would result in dozens of different combinations. After carefully comparing each of these combinations one by one, the NSE1000 A, B, and G were selected.
We would like you to compare the three models if possible, although we appreciate it may be difficult for you to buy all three. At any rate, we hope you will choose the sound that you like best.
