The Final Audio Design Sonorous II Headphones Excel with High Frequency Harmonic Overtone Reproduction!

The Sonorous II:
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, the Sonorous II 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 Audio Design 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 Audio Design has applied even more precise tuning based on knowledge obtained through the development of Sonorous VIII and Sonorous X.

What is a BAM mechanism?
Final Audio Design 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. Final Audio went back to the beginning and reviewed the performance of the balanced armature driver, focusing their attention on something previously overlooked, airflow inside the housing. Final Audio Design 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, they achieved a BA type that at the same time made for natural listening the user doesn't tire of.

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 Audio Design 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.

Sound quality reviews:
A model characterized by beautiful high frequency harmonic overtone reproduction. These headphones strike a good balance with their high frequencies with a sense of openness, their lively low frequencies and smooth middle frequencies. Perfectly suited to listening to female vocals and pop music. These are the entry model of Final Audio Design's headphones, but their ability is not to be taken lightly!
