Delivers a vast sound stage never before experienced until now.
With the synergistic effect of a hybrid design that merges balanced armature with a 50mm diameter dynamic driver unit coupled with BAM mechanism, Final has achieved an extraordinarily vast sound stage. The music fixed inside our heads with headphones up until now vibrates in a vast space from side to side and with depth.
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 has applied even more precise tuning based on knowledge obtained through the development of SONOROUS VIII and SONOROUS X.
Balanced armature driver developed in-house
Balanced armature driver unit developed by Final for optimal use as a tweeter. Final has paid special attention to our choice of materials used in our pursuit of sound quality, utilizing a permalloy with a high level of magnetic permeability in the magnetic circuit.
Newly developed 50 mm φ dynamic driver
A driver unit with a diameter of 50mm, newly designed for SONOROUS. By increasing the precision of the parts, it has become possible to make the gap between the magnetic circuit, the pole piece and the yoke narrower than with common products. A powerful neodymium magnet is coupled with this, making for a high magnetic flux density. The result is clear sound quality.
Final has re-examined the shape of the tangential edge and have employed a lightweight diaphragm with a heightened responsiveness to micro-signals.
The voice coil is copper-clad aluminum wire CCAW. Clear, crisp bass tones are achieved with the combination of a magnetic circuit with a high driving force and a light vibration system.
So as not to inhibit the sound emanating from the driver unit, and so that there is no unnecessary added reverberation, a form that is as slim yet as strong as possible has been pursued. This contributes to clear sound quality.
Machined stainless steel housing
In combination with the ABS housing is the machined stainless steel housing that reduces unnecessary vibrations. To demonstrate maximum results, it is necessary that both are machined with the utmost accuracy, and as such, the stainless steel has also been machined.
The surface is finished with the tool marks from the machining process left as is. They are machined domestically at a leading specialty machining factory. Taking sufficient time and using extremely finely edged tools, this careful manufacturing is teeming with the know-how of Japanese craftspeople.
Ear pads with the optimum resilience for a comfortable fit
What plays an important part in sound quality is the fit between the user's ear and the ear pad. If there is space between the two, then bass tones are lost; if the ear pad presses against the user's ear with too much pressure, then apart from it being uncomfortable, the acoustic pressure of the bass tones rise too high, resulting in negative influences on sound quality. In spite of this, there was no evolution seen in the ear pads on the market, and they continued to be made using the same structure for many years.
Final's engineers who had been involved in the development of corsets to participate in developing our ear pads, re-examined the fit between the user's ear and the ear pad. By employing the appropriate technology – pursuing synthetic leather with the best elasticity and the best sponge cutting and adopting ultrasound fusion for the adhesion of the synthetic leather to the inner frame – they constructed an unwrinkled, three-dimensional form with just the right amount of tension to it.
Aluminum back plate
A 1.5mm thick aluminum back plate at the back of the driver unit for achieving air pressure balance. Not only air pressure balance but also great results in the suppression of unnecessary vibrations are manifested.
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.
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.
