Final Audio Design Sonorous II & III
Final Audio Design introduces its most affordable over-ear headphones - the Sonorous II and Sonorous III. Both feature technologies used in the flagship Sonorous X model. It 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, new models excel in the generation of high frequency harmonic overtones, achieving high resolution sound.
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 Audio Design engineers 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 is the approach of optimizing the balance of pressure at the front and rear of the diaphragm. Sonorous II and Sonorous III have been tuned to an extremely accurate level based on new knowledge expertise gained from the development of Sonorous VIII and Sonorous X. 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.
With Sonorous X, the flagship model of the Sonorous series, Final Audio Design 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.
A metal plated monaural plug with a diameter of 3.5 mm 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 by 90 degrees.
