Excels in terms of high frequency harmonic overtone reproduction.
The flagship model SONOROUS X employs a driver unit integrated with the front plate, which results in resonance being suppressed and clear sound quality. With the same titanium diaphragm employed with SONOROUS X, this model excels in the generation of high frequency harmonic overtones, achieving high resolution sound.
Ear pads with an internal sound absorption section that contribute to clear sound quality
The ear pads play an important part in sound quality. When there is a space between the ear pad and the ear, low frequency acoustic pressure changes greatly, and this greatly influences sound quality. So as to achieve a superior fit where it is hard to create a space, Final has employed synthetic leather, which has an equal amount of flexibility both horizontally and vertically, and have chosen a sponge with just the right amount of flexibility. Establishing apertures on the inside and the outside of the ear pads makes for clear sound quality with sealed headphones.
BAM mechanism that realizes bass tones and deep three-dimensional space 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. With SONOROUS II, Final has applied even more precise tuning based on knowledge obtained through the development of SONOROUS VIII and SONOROUS X.
Rigid ABS housing with a rough coating
To achieve a high level of precision with the hard ABS housing, simulations were carried out until the appropriate level of fluidity with respect to the molding material was achieved. A textured finish that is also used with high-grade camera lenses is applied, and unnecessary vibrations are suppressed.
Titanium diaphragm driver unit is integrated into the front plate
With SONOROUS X, the flagship model of the SONOROUS series, Final has integrated the driver unit with the front plate, and this suppresses resonance as well as realizing clear sound quality. The housing employs hard resin comprised of hard polycarbonate strengthened with 30% glass added to it. Resonance is suppressed and clear sound quality is achieved. Titanium has been employed for the diaphragm. This plays a role in enhancing resolution and the generation of high frequency harmonic overtones.
Detachable cable with locking function
A metal plated monaural plug with a diameter of 3.5mm is employed for the connector on the headphones. By employing a connector with a long track record, trouble resulting from poor connection through changes over time is avoided. This is a cable with a locking mechanism that rotates 90 degrees.
