Final Audio Sonorous III

$399.00

The current entry point to the Sonorous line from Final Audio, the Sonorous III features much of the same technology as it’s bigger more expensive brothers. For an entry level price, the Sonorous III packs a powerful punch.

Description

The Sonorous III is a beneficiary of the flagship model SONOROUS X employing a driver unit integrated with the front plate, which results in resonance being suppressed and clear sound quality. Here, clear, transparent sound combined with a vast sound stage is generated owing to the same titanium diaphragm employed with SONOROUS X. Final Audio has achieved sound quality that faithfully reproduces the source music and is pleasant to listen to.

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, the Sonorous III employs synthetic leather, which has an equal amount of flexibility both horizontally and vertically, and has 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.

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 III, we’ve applied even more precise tuning based on knowledge obtained through the development of SONOROUS VIII and SONOROUS X.

Final Audio has 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. They went back to the beginning and reviewed the performance of the balanced armature driver, focusing their attention on something that had been previously overlooked; airflow inside the housing. Final Audio 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, The Sonorous III achieves a BA type that at the same time made for natural listening the user doesn’t tire of.

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 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.

You can demo a selection of Final Audio headphones inside the shop if you’re in the Southern California.
