The Sonorous series headphones from Final Audio Designs were designed to reproduce the realism of vocals and instruments reverberating in a space. The award-winning, lightweight Sonorous III model offers monitor-like sound quality with vast sound stage. These headphones are extremely well-balanced, faithfully reproduce the source music and are pleasant to listen to.

Ear Pads

Great fitting ear pads is the key to superior sound quality. Final achieves snugly fit by using the right materials and tested know-how: employing synthetic leather, which has an equal amount of flexibility both horizontally and vertically, in addition to 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.

Balancing Air Movement

Listen without tiring - the Final's engineers worked hard to bring you bass tones and deep, three-dimensional space reproduction with the in-house developed BAM mechanism. Achieved through testing and fine-tuning previous models, you know that Sonorous II is the version to have.

Suppressed Vibrations

Final employs rigid ABS housing and textured finish to ensure unnecessary vibrations are suppressed. To achieve the 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. 

Titanium Diaphragm

Integrating titanium into to the diaphragm driver with the front plate enhances sound resolution, generates harmonic overtones and helps achieve clear sound quality. That is the reason why Final Audio Design makes sure this standard is used in their Sonorous II headphones.

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.
