Audio46's Opinion
The Sonorous III stole our hearts with its punchy bass and warm retro-ish feel. The mid-frequencies continue the low-end warmth, making vocals smooth and enjoyable without being overpowering. The high-frequencies also offer a fluid, analog-like sound, well-extended but never fatiguing . The soundstage also benefits from the slightly bigger driver housing, providing an open-back quality in a closed-back headphone, allowing the music to breathe with a generous amount of space. For sure, Final Audio has done a commendable job in mastering the refined and enjoyable sound signature of the Sonorous III.

Final Audio Sonorous III Closed-Back Over-Ear Headphones
In the Final Audio Sonorous III Closed-Back Over-Ear Headphones, 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, we’ve 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 III has 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, we 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 3.5mm 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°.
