The prestige model of the SONOROUS series, SONOROUS X
eliminates compromise.
We think you will be surprised not only by the clarity and vividness, but also by the sense of realism imbued in the sound produced by these headphones, something that hasn't been experienced in headphones until now. The 50 mm diameter driver unit with titanium diaphragm is integrated with the front plate and has been machined from pure aluminum. The principal parts are composed of machined aluminum and stainless steel. It was necessary to create the housing from a rigid metal so as to achieve the sense of realism.
This is a resolute prestige model, the zenith of the SONOROUS series.

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 X 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.
Integrated machined aluminum front plate and housing + titanium diaphragm driver unit
Usually, the driver unit housing is made of ABS. The driver unit is produced independently, and is attached to the front plate, which is made of the same ABS. The section where the two are attached along with the ABS resin flex and resonate with the amplitude of the driver unit. With SONOROUS X, machining the driver unit and the front plate as an integrated unit from the same piece of aluminum magnesium alloy made it possible to reduce the instabilities that adversely affected sound quality such as resonance and deflection, as well as those arising due to the fit of the adhesive. Doing so resulted in the actualization of crystal clear sound. 

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.
