Final Audio SONOROUS III Hard Polycarbonate Closed Back Headphone

The flagship model SONOROUS X employs 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. We've achieved sound quality that faithfully reproduces the source music and is pleasant to listen to.

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

* What is a BAM mechanism?
At final, Final Audio 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 our attention on something Final Audio had 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, Final Audio achieved a BA type that at the same time made for natural listening the user doesn't tire of.
