Dense music representation and a vast sound stage.
We think you will be surprised by the vast sound stage and the real, vivid instrumental sound. The 50mm dynamic driver unit with its aluminum-machined housing is created with never before seen precision. This precision is manifested in the sound. All sounds in the music source are expressed; you are bound to encounter sounds you were never aware of before in songs you are used to hearing.
A BAM (Balancing Air Movement) mechanism that delivers bass tones and deep, three-dimensional spatial reproduction
A BAM (Balancing Air Movement) mechanism developed for balanced armature drivers has been employed with a dynamic driver. With BAM, the idea is to optimize the pressure balance between the front and back of the diaphragm. To thoroughly follow through with this idea, SONOROUS VIII is sealed so that no air leaks from inside the housing.

* What is a BAM mechanism?
At final, we decided to focus on developing technology for the reproduction of bass tones and three-dimensional space with the full-range reproduction of a theoretically unproblematic single driver unit, rather than taking things in a multiway direction. We went back to the beginning and reviewed the performance of the balanced armature driver, focusing our attention on something we had previously overlooked ? airflow inside the housing. We developed BAM (Balancing Air Movement), a mechanism that optimizes airflow inside the housing through the creation of an aperture in the driver unit, which is usually sealed. While achieving bass tones and deep, three-dimensional spatial representation, which proved difficult with single driver full-range reproduction, we achieved a BA type that at the same time made for natural listening the user doesn't tire of.
Machined aluminum housing + titanium diaphragm driver unit
A driver unit is an object that is usually made of molded ABS. With SONOROUS VIII, we've used machined aluminum for the housing of the driver unit. We've suppressed the resonance and distortion caused by the amplitude of the driver unit and have achieved clear sound with little blur.

Having tested a variety of materials for the diaphragm, we employed titanium, which emits a well-balanced sound over a wide bandwidth. To accurately assemble the titanium diaphragm, we developed specialty jigs and assembly equipment.
Rigid ABS housing with textured finish
To achieve a high level of accuracy with the extremely hard, texture casting finished ABS housing, which is also used with high grade camera lenses, simulations were carried out until the appropriate level of fluidity with respect to the molding materials was achieved. Realizing high circularity led to the realization of a highly accurate fit with the machined stainless housing. To put the concept of reducing unnecessary vibrations through the combination of different materials with different resonance points into practice, ingenuity has also been exercised in those sections that are not readily visible.
Ear pads with a comfortable fit and optimal "suppleness"
Ear pads play a very important role in sound quality. One of these roles relates to the matter of fitting. When there is space between the ear and the ear pad, low-level acoustic pressure changes considerably and has significant influence on sound quality. Because of this, the choice of both ear pads and the sponge material inside them is important. Another aspect is that they are a component that changes greatly over time; with this aging, the sound from the headphones changes in a favorable direction as they are used, and changes in the shape of the ear pad are also a large contributing factor. The ear pad molding itself to the shape of the ear is a positive change, but any excessive change after this may mean a diversion from favorable sound.

With this, trial listening and comfortable contact with the ear in mind, and with the same amount of stretch both vertically and horizontally, synthetic leather, which changes just the right amount with time, has been employed.
Detachable cable with locking mechanism
For the connector on the headphones, a 3.5mm diameter gold-plated monaural plug has been employed.
By employing a connector with a lengthy track record, trouble with loose connections has been avoided.
The cable has a 90-degree rotary locking mechanism. 1.5m and 3m cables are included.
Machined stainless steel housing
In combination with the machined aluminum housing is the machined stainless steel housing that reduces unnecessary vibrations. To demonstrate maximum results, it is necessary that both are machined with the utmost accuracy, and as such, the stainless steel has also been machined. The surface is finished with the tool marks from the machining process left as is. They are machined domestically at a leading specialty machining factory. Taking sufficient time and using extremely finely edged tools, this careful manufacturing is teeming with the knowhow of Japanese craftspeople.
